T5: native component needs asset: effects.js but I want to combine/minify js-files
I've decorated ClientInfrastructure to supply my own set of required js-files. this is only 1 file containing complete prototype and a modified version of scriptaculous (stripped what I dont need, and some overridden controls) This all works well, but there is still a native component that injects effects.js. Is there a way to override which file this component needs to look at? At the moment I haven't got an idea which component is triggering the inclusion of effects.js. I don't recall having any component in use (direct or subclassed) that uses it. of course i could always rename my javascript file to effects.js but this would be a matintenace nightmare: new version of scriptaculous -- overwrite effects.js.. any help appreciated... thanks Geert-Jan -- View this message in context: http://n2.nabble.com/T5-native-component-needs-asset-effects-js-but-I-want-to-combine-minify-js-files-tp4759964p4759964.html Sent from the Tapestry Users mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
T5: logging statements logged twice using Log4j
Hi, I'm having the problem (always had as far as I remember, but it starts to bug me now) that when using Log4j with Tapestry every log-statement is logged twice to the console. For example, the last few lines before the tapestry is initialized look like this: INFO - ApplicationContext.log(646) | org.tuckey.web.filters.urlrewrite.utils.Log ERROR: logLevelConf: null org.tuckey.web.filters.urlrewrite.utils.Log ERROR: logLevelConf: null INFO - ApplicationContext.log(646) | org.tuckey.web.filters.urlrewrite.UrlRewriteFilter INFO: loaded (conf ok) org.tuckey.web.filters.urlrewrite.UrlRewriteFilter INFO: loaded (conf ok) INFO - Http11BaseProtocol.init(144) | Initializing Coyote HTTP/1.1 on http-8080 Initializing Coyote HTTP/1.1 on http-8080 INFO - Http11BaseProtocol.start(156) | Starting Coyote HTTP/1.1 on http-8080 Starting Coyote HTTP/1.1 on http-8080 Since the formatting of the 'duplicates' is different I figure there must somehow be a different logger at work. I already tried pluggin in the vanilla logging.properties from the tapestry 5 archetype but nothing changes. Anyone got any clue where to look? p.s: I'm running in Tomcat 5.5 does this have anything to do with it? -- View this message in context: http://n2.nabble.com/T5-logging-statements-logged-twice-using-Log4j-tp4597599p4597599.html Sent from the Tapestry Users mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Re: T5: some automagical way to export versioned assets to CDN?
Just to get this straight: That code takes care of rewiring the templates to use the correct asset-path right? But it doesn't take care of actually getting the updated assets to CDN in the first place? Thanks, Geert-Jan 2010/1/22 Jun Tsai [via Tapestry Users] ml-node+4438110-1664249...@n2.nabble.comml-node%2b4438110-1664249...@n2.nabble.com You can override AssetPathConverter service. example: http://code.google.com/p/corner/source/browse/corner3/trunk/src/main/java/corner/asset/services/impl/CDNAssetPathConverterImpl.java 2010/1/22 britske [hidden email]http://n2.nabble.com/user/SendEmail.jtp?type=nodenode=4438110i=0 Versioning in Tapestry is really easy. Just increment the version-nr in appModule and you're set. However, I'd like my assets to live on a CDN. (Amazon S3 + cloudfront) . For this to work (along with versioning) I would have to do 2 conceptual things: 1. export assets to a specific s3 bucket linked to cloudfront. 2. point html-code to correct path. To do this manually I'd have to: - up the version in appmodule by hand. - create a new s3 bucket by hand (with the version-nr encoded in it) - ? copy/ move the versioned assets-directory created by Tapestry to the newly created S3- bucket ( I assume it is created on-the-fly on run-time and are saved to disk? - point html-code to the new correct path. I assume I can code this once, bc. I must be able to access the versionnr, and along with the static s3-path be able to create the path to the newly created s3-bucket. All this is possible, but I would like it to be automated. Is this already possible (with some minor tweaking) If not, where would I start looking to automate this? any pointers highly appreciated.

T5: how to eval 'canned' expansions (stored in db)?
I have a page showing different blocks (ala myYahoo , netvibes, etc) .
Each block is a different component.
One of these components gets it's content from a database and writes it in
the BeginRender() - phase. The content to store in the database is some
html possibly with tapestry expansions. E.g: today is: #foo
${dateAsString} or something. (The database route is the way to go for me
in this scenario, as content is not known at design-time)
Is there a way to evaluate the expansions in the the html in the
component.beginRender phase and render the result?
This would be pretty powerful stuff.
Thanks,
Geert-Jan

You can inject the PropertyConduitSource service (it is public). You
can obtain PropertyConduits, which are the compiled versions of
property expressions (as used by parameter bindings).
The PCS caches the result, so it's reasonable to pass an a class and
an expression, get back a PC, and discard it.

t5: when updating zone, non persistent fields outside of zone are null, is this expected?
Perhaps a pretty ignorant question, but: I have a searchresults-page with a zone-component which is updated through an ajax call. Another component lives within the zone-component and it's setuprender-method is called. In this method I need to access the 'searchresults-object' which is stored as a Map in the surrounding page. this map is NOT annotated with @Persist or anything Somehow I figured that since the page itself isn't updated, the 'searchresults-object' would still be available in the page, but instead the value is null. Did I completely misunderstood this, or might something else be the problem? If I misunderstood, what would be the best way to have a zone that has access to a results-set such as my 'searchresults-object' for which calculating the results again is out of the question (from a performance standpoint) I guess making it @Persist(flash) would help, but how does the impact performance, it destroys the option of tapestry reusing the page right?

T5: HibernateEntityValueEncoder nullpointerException after Tapestry update
I'm in the process of updating from 5.0.17 to 5.1.0.5 and breaking my head on
this one:
Getting a NullPointerException in HibernateEntityValueEncoder when trying to
loop a hibernate Entity where the entity has a multi-column id.
I actually have this with every entity with a multi-column id so please
consider the below as an example of the generalized case. See relevant
snippets as well as trace below.
After some investigation it SEEMS that:
- looping of entities (for which HibernateEntityValueEncoder is called)
WORKS for entities with standard IDs
- looping FAILS for entities with an @IdClass specified (i.e: multi-column
id)\
- querying of all entities works (so it isn't a hibernate issue as far as I
can tell)
I double checked this by transforming the mapped class to contain a single
id instead of the multi-column id
(I simply concatenated the columns that made up the id in sql and updated
this value to a new column. Afterwards I assigned this new column to be the
id of the table, and updated the hibernate entity accordingly. )
Afterwards the code just works.
Is there a reason why multi-column entities don't seem to be working in my
case? All dependencies are correct as far as I can tell. Anyone experienced
this?
relevant code:
.tml
t:loop source=CityTemperaturesOrEmptyIfNonFound value=CurCityTemp !--
LINE GIVING ERROR --
${CurCityTemp.temp}
/t:loop
Please note that simply calling CityTemperaturesOrEmptyIfNonFound from a
different method just works and returned results. It's just that the
looping-code raises the error because the entity can't be encoded.

Re: T5: HibernateEntityValueEncoder nullpointerException after Tapestry update
I'm not sure if HibernateEntityValueEncoder called
PersistentClass.getIdentifierProperty() before (in 5.0.x) when my code
worked...
getIdentifierProperty() returns an instance of hibernate.mapping.Property
which may be a Composite ID (which seems to be the official name for
multi-column ids). In other words this method should return the id-property
of my class even though this 'property' isn't defined by a single field in
my case.
So I think it should return a property, although a multi-valued one.
All this indeed strongly suggests that it is a hibernate issue..
I will investigate further.
Thanks.
Ulrich Stärk wrote:
This /seems/ to be a Hibernate issue.
PersistentClass.getIdentifierProperty() is apparently
returning null.
On second thought this seems just natural since there is no property
representing your Id.

Re: t5: strategy for caching html output of component
ok, tried a couple of things, but none of them work: 1. in the container component keep track of the element that is created by the container component. in the afterRender fetch the html as element.toString() and put to cache. in the beginrender method check the cache and if found -- write to markupWriter using markwriter.addRaw(htmlFromCache); This gives an OOM-error since apparently Markupwriter doens't like having to construct so many dom elements all at once, 2. Better solution would be to use TextStreamResponse. However, I would like to return the html in this streamresponse in the same render methods of the component. However, I only seem to be able to return a streamresponse from an event method (such as onActivate, which seems the recommended way to render using StreamResponse) . Since a Component doesn't have a onActivate I'm out of luck. Ther is some metnion in earlier posts of using a page's onActivate to return a TextStreamResponse but I don't see how this could help me... any help is highly appreciated.

T5: how to add tuckey url rewrite filter to Tapestry Context
I saw a recent post about setting up Tuckey url-rewrite filter to set up some url rewriting in conjuction with Tapestry so decided to try it out. All works fine when using 'redirects': rule from/test/from to type=redirect/zoeken/to /rule However the real power (in my opinion) comes with forwarding url's so that the url's in the browser window do not change, like so: rule from/test/from to/zoeken/to /rule localhost:8080/zoeken maps to a page 'zoeken' in Tapestry. When setting a rewrite rule from redirect to forward (which is the default) the filter can't find the resource to rewrite to anymore. According to the rewrite manual at: http://tuckey.org/urlrewrite/manual/2.6/ this happens when: the to URL is not in the same context as UrlRewriteFilter. So I'm guessing that's what causing the problems here. The problem is that I don't have a clue where to put the UrlRewriteFilter so it is included in the same context as my tapestry app. Currently, UrlRewriteFilter is supplied as a .jar in a /lib folder within the WEB-INF folder (which is the correct place according to the rewrite manual) Web.xml correctly locates and initalizes the filter so that part works fine. SO I'm left with the question: were do I put this .jar file so it will be included in the 'Tapestry' web context? I'm using Tomcat 5.5 btw since this might be related to that as well. I'm just not sure. Probably usless info: the context of this tapestry app is ROOT (which maps to the default in Tomcat) Anyone?

T5: how to update zone on dom load
Hi,
I've created a zone which get's a couple of updates from various external
websites. The zone initally (on page load) contains some local info, but
needs to be dynamically extends with the sources extracted from these
websites. I want to call a server-side method (onActionFromRefreshZone)
which updates this zone (and starts fetching the info from the external
websites) on the dom-loaded event.
The zone is in place and I checked that it works with an actionlink:
# update
However as said I want to call the method onActionFromRefreshZone on
dom-loaded.
I already have the javascript method in place which is called on this
event.However I have no clue how to call the method in a Asynchrnous way. I
tried including the url of the above actionlink as such:
function functionWhichIsCalledOnDomLoaded(){
new Ajax.Request('/thepage.refreshzone?t:zone=zone1;t:ac=/id-1-66590/',
{
method:'get' });
}
but this doens't work.
Somehow I'm thinking this isn't the correct way anyhow and that there should
be a more elegant way / more T5-way to call a server-side method
asynchronously.
Thanks,
Geert-Jan

T5: actionlink calls onActivate twice: detecting first time
as part of onActivate I do some processing: - user validation - parsing of params - DAO / repository calls etc. I want to avoid as much of this work as possible obviously. When this counts a lot is when actions are used. In that case the flow is like: click -- onActivate -- onAction -- onActivate. (please comment if this is not as it should be) ultimately leading to calling the above code twice, while the first-time (the activate before the onAction) this particular code doesn't need to be executed (except the validation). This caused me to think that perhaps using the onActivate method isn't the best place to load entities which are used for rendering (and not for page navigation). However, methods like beginRender and setupRender are called twice as well. Isn't this strange?? I thought setupRender, beginRender as well as any method called through the page-template would be called in the Render-action only. (So in this case only after the second onActivate occurs) correct? So basically what I'm asking is: - is the observerd behavior correct? or does this sound strange? - where would be the best plave of isolating information neded to run in the render-action only? And how would I make sure that indeed it is only run in the Render-action?

Re: T5: what part of tapestry adds Jsessionid
Yep I tried that, but when I converted a working stripping servletfilter to a
requestfiler, I have to deal with tapestry's request and response in
addition to sevlet.HttpServletRequest and servlet.httpServletRepsonse.
Although I override both (Response and HttpServletResponse, since I guess
some code uses Response while some use HttpServletResponse) still no luck.
My code (almost an exact copy of the servlet filter I had ealier, but with
overwriting the Tapestry-reponse as well) is:
public boolean service(Request request, Response response, RequestHandler
handler)
throws IOException {
if (request.isRequestedSessionIdValid()
_globals.getHTTPServletRequest().getCookies()==null)
{
Session session = request.getSession(false);
if (session != null) session.invalidate();
// wrap response to remove URL encoding
HttpServletResponse httpResponse =
_globals.getHTTPServletResponse();
HttpServletResponseWrapper wrappedResponse = new
HttpServletResponseWrapper(httpResponse)
{
@Override
public String encodeRedirectUrl(String url) {
return url; }
@Override
public String encodeRedirectURL(String url) {
return url; }
@Override
public String encodeUrl(String url) { return
url; }
@Override
public String encodeURL(String url) { return
url; }
};
response = new ResponseImpl(wrappedResponse);
_globals.storeServletRequestResponse(_globals.getHTTPServletRequest(),
wrappedResponse);
_globals.storeRequestResponse(request, response);
}
return handler.service(request, response);
}
But still JSessionId in the results. (although actionlinks take a cycle more
to pick up the JSessionID than without the filter)
Anyone?

Since search-engines don't login these 2 groups are nice mutually

and so it's a clean cut when to strip the JSessionid and when not.
Except that I'm still not sure how to do it.
Wrapping the request and response in a handler (before Tapestry

exactly the

That's why I think it has to do with some internal tapestry

T5: possible to get the 'real' object instead of a proxy?
When injecting a (hibernate) Session a proxy to the actual session is returned. However, when using the session in a lot of my dao-services I need to have access to the 'real' underlying session instead of just the proxy. Is there a way to do this? Some background: after revisioning my dao/repository layer a bit I want to rely on hibernate's DetachedCriteria for a lot of queries. THis basically enables you to build hibernate criteria's without having a session handy. (very useful in the light of MVC, etc. ) However, when actually executing these detachedcriteria through detachedcrit.getExecutableCriteria(Session session) a 'real' session has to be supplied since the method makes uses the underlying implementation instead of just the session-interface.

Re: T5: possible to get the 'real' object instead of a proxy?
I meant that the hibernate-implementation is bad design here. Having a method: getExecutableCriteria(Session session) to me would mean that any object adhering to the interface Session could be passed as a parameter. However getExecutableCriteria really needs a SessionImpl to be passed so that should have been the type of the param. Filip S.

T5: what part of tapestry adds Jsessionid
partially related to a post I send a couple of days ago, but perhaps this
explains better what I'm trying to do.
I'm trying to strip the jSessionId from displaying in the url if:
1. user doesn't have cookies (otherwise it won't display anyway)
2. user is not logged in.
I wanted to implement this as a filter, but I have to go with a dispather
since to see if a user is logged in I need to have access to the ASM, which
I can't get to in a filter.
Now somewhere in between all the HttpSevletRequest to tapestry.request
comversion, etc. tapestry decides to take over the JSessionId provided by
the HttpServletRequest. I want to intercept this call somehow and strip the
JSessionId from the request.
I implemented a Dispatcher (the last in the line before onActivate is
called) and basically wrapped (subclassed) HttpServletRequest and
HttpServletResponse to return null for the sessionid and have redirecturl
return url. My own HttpServlet get's called in the app (and returns null for
getrequestedSessionId()) This request is added as a constructor param to a
newly created tapestry.requestImpl which are both saved to RequestGlobals. I
though that should do the trick
not...
Apperantly somehow the jsessionid is picked up anyway although (when
expecting requestglobals.getHttpServletRequest.getRequstedSessionId() in
page.onactivate() this correctly returns null).
Anyone?
Thanks.

Re: T5: what part of tapestry adds Jsessionid
yeah I realize that JSessionId is there for the session, but I want to build
functionality into a dispatcher that strips this jsessionid from the request
if a user is not logged in (logged in in my app means that a User-instance
exists in the ASM) and if the user has cookies disabled.
The rationale is
that I don't want search-engines to see the JSessionid, but I want to enable
users without cookies to login and track their settings using JSessionID in
the url.
Since search-engines don't login these 2 groups are nice mutually exclusive
and so it's a clean cut when to strip the JSessionid and when not.
Except that I'm still not sure how to do it.
Wrapping the request and response in a handler (before Tapestry comes in
action) and stripping it like that works, but doing it almost exactly the
same in a dispather doesn't .
That's why I think it has to do with some internal tapestry processing.
Do you have an idea where to look?

I had to override the tapestry Form component so it only stored the

T5: getting current hibernate session (per-thread) from singleton-service
I found some partial references on the list, but nothing that really answered
the question, so:
How can I get the current (per-thread) hibernate-session (as configured
through tapestry-hibernate) from a singleton custom tapestry service?
For reference:
I have a MySingleton-class build as a tapestry service.
MySingleton.getSingleton().getCurrentSession() should give me the current
session (thread-bound) as managed by tapestry-hibernate.
This would enable me to access the current session from any class (not just
components or tapestry services)
I tried 3 methods, 2 of which don't work, and 1 I'm not certain
Method 1:
build the MySingleton-class and inject Session at constructortime.
Problem: the hibernate session that is created on constructor-time stays
assoaciated with MySingleton (correct?). So this doesn't give a
session-per-thread.
Method 2:
build the MySingleton-class and inject HibernateSessionSource
getCurrentSession(){
return hibernateSessionSource.getSessionFactory().getCurrentSession();
}
Problem:
but this gives error:
org.hibernate.HibernateException: No CurrentSessionContext configured!
I think this happens because the way the session is accessed bypasses the
tapestry-hibernate session-in-view filter (HibernateSessionManager) which
takes care of providing the context.
Is there any way to make getSessionFactory() aware of the
HibernateSessionManager? So the above works?
Method 3:
build the MySingleton-class and inject ProperyShadowBuilder and
HibernateSessionManager
I figured this calling hibernateSessionManager.getSession() would give me
the needed context (which lacked from method 2) . The problem is that
HibernateSessionManager is not a singleton either.
I thought this could be bypassed by doing :
getCurrentSession(){
return shadowBuilder.build(hibernateSessionManager, session,
Session.class);
}
However this still doens't ensure (I think) that hibernateSessionManager
belongs to the current thread.
Can anyone shed some light on this? I would highly appreciate it!
Cheers,

Re: T5: getting current hibernate session (per-thread) from singleton-service
Wow I love that. Somehow I mistakenly thought it didn't work that way,
thanks.
As a related question :
is there a way to get the 'real' session instead of the proxy on a call to
getSession()
The reason I'm asking is that in a lot of cases I want to use (Hibernate's)
DetachedCriteria's, so I can make a criteria, pass that as a parameter to a
repository and let the repository get the current session and create a real
criteria. (For reasons of seperation)
This is done through detachedCriteria.getExecutableCriteria(getSession());
However this always gives a classCastException, like:
java.lang.ClassCastException: $Session_11b08fbaf1e cannot be cast to
org.hibernate.engine.SessionImplementor.
for a related post (similar problem) see:
http://www.nabble.com/Hivemind-creates-proxy-Hibernate-Session-td9845916.html
Therefore I need the 'real' object.
diong getSession().getSessionFactory().getCurrentSession() would solve my
problem, since that would be both the session of the current thread and the
real object, but (as described in method 2 of my post) the context assigned
to be tapestry-hibernate isn't there when accessing the session in this way.
Any suggestions on how to solve this as well? Much apreciated!

Re: stripping jsessionid in custom dispatcher depending on ASM.
perhaps I should have mentioned that the code for checking if the
user-instance exists or not isn't here yet, but it isn't really relevant for
the problem. Thanks.
Britske wrote:
I want to strip JsessionId from the url (for browsers who dont support
cookies) for SEO purposes.
btw: perhaps a bit long-winded as to the why's, but it may help others.
At first I implemented a servletfilter (from
http://randomcoder.com/articles/jsessionid-considered-harmful)
which basically consists of passing a subclassed httpServletResponse where
i've overwritten the encodeUrl() method to not to include the jsessionid.
This works well.
However I do not want to strip the jsesisonid when the user has logged in.
The rationale here is that I really do need a session when a user is
logged in, and since a searchengine doesn't login (at least I don't
program for it) It can't harm to make this exception.
The application recognizes that a user is logged in if a User-instance is
present in the ASM (ApplicationStateManager).
This means I have to let the notion of a requesthandler go, and go instead
with a tapestry dispatcher, since a servlet requesthandler has no way f
getting the ASM of the current user. (Is this correct?)
Not much changed to the dispather (in relationship to the code in the
requestfilter before). The Dispatcher is also correctly registered in
AppModule etc.
The problem is that although I see that jsessionid is stripped in the
custom encodeUrl-method, if appears afterwards in request (as noticed in
the address-bar). So my question is: What code inserts the
jsessionid-again, after the Response.encodeUrl()-method, and how can I
change it's behavior?
the relevant code:
//Appmodule
public static void bind(ServiceBinder binder)
{
binder.bind(AccessController.class).withId(AccessController);
binder.bind(AutoLoginController.class).withId(AutoLoginController);
binder.bind(SessionStripController.class).withId(SessionStripController);
}
public void contributeMasterDispatcher(OrderedConfigurationDispatcher
configuration,
@InjectService(AccessController) Dispatcher
accessController,
@InjectService(AutoLoginController) Dispatcher
autoLoginController,
@InjectService(SessionStripController) Dispatcher
sessionStripController) {
configuration.add(AccessController, accessController,
before:PageRender);
configuration.add(AutoLoginController, autoLoginController,
before:AccessController);
configuration.add(SessionStripController,
sessionStripController,before:AutoLoginController);
}
//sessionstripcontroller
public final class SessionStripController implements Dispatcher {
private ApplicationStateManager asm;
private RequestGlobals globals;
public SessionStripController(ApplicationStateManager asm,RequestGlobals
globals){
this.asm = asm;
this.globals = globals;
}
public boolean dispatch(Request req, Response response) throws
IOException {
// clear session if session id in URL
if (req.isRequestedSessionIdValid()
globals.getHTTPServletRequest().getCookies()==null)
{
Session session = req.getSession(false);
if (session != null) session.invalidate();
ServletResponseWrapper wrapResp = new
ServletResponseWrapper(globals.getHTTPServletResponse());
globals.storeRequestResponse(req, wrapResp);
}
return false;
}
}
//ServletResponseWrapper
public class ServletResponseWrapper extends ResponseImpl{
public ServletResponseWrapper(HttpServletResponse response) {
super(response);
// TODO Auto-generated constructor stub
}
@Override
public String encodeRedirectURL(String url) {
url = super.encodeRedirectURL(url);
return url;
}
@Override
public String encodeURL(String url) {
url = super.encodeURL(url);
url = url.substring(0,url.indexOf(;));
return url;
}
}
btw: encodeRedirectURL and encodeURL can just return url straightaway,
but the above code enabled me to see that indeed this code stripped the
added jsessionid that super.encode*Url() added. So where is the other
method that's adding jsessionid?

hi, I was quickly testing creating and updating userprofiles using beaneditform. To me, the most logical thing to do was combine Create and Update in one page: if a User-instance exists in the applicationstate -- user is displayed using beaneditform and fields can be edited, if no user-instance exists in the applicaitonstate or no applicaiton state exists -- create new user-instance all works fine, except that I want a cancel button to exist, which rollbacks all actions performed on the bound user-instance. So, if the user instance already existed before, it should rollback to the field-values before opening the edit screen. Since editing the beaneditform directly sets the fields of the user-instance, all old values are overwritten. The question: of course I can get the persisted user from db when the 'cancel'-button is pressed and overwrite the user in applicationstate with this fetched used from db, but this requires a db-call which I want to avoid. Best would be to create a clone of the user-instance in onActivate which I can use instead of the fetched instance from db. However, the fields of the user-profiel are likely to change, so I want to clone 'dynamically'. Any bean*-functionality that I can leverage for this? Moreover, about that cancel-button, does beaneditform has an option to display a cancel-button or something alike, with events I can bind to? Thanks in advance, Geert-Jan -- View this message in context: http://www.nabble.com/t5%3A-rollback-when-profile-update-is-cancelled-with-beaneditform-tp18320046p18320046.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
T5: beaneditform: properties don't get populated although model is bound
I've got a beaneditform which displays a userprofile, with among other things
2 passwordsfields.
When displaying an existing userprofile all fields except the password
fields are rendered, (the password fields remain empty), although values for
the password-fields exists in the bound userprofile.
These password fields as exactly the fields that I overwrite using the
parameter-construction.
Anyone knows why this happens?
relevant snippets:
private User user;
@Persist(flash) private User userOld;
public void onActivate(Object[] list){
if(isUserExists()){
user = getSessionModel().getUser();
userOld = user.clone();
}
}
//template
t:beaneditform t:id=beanEditForm object=user
submitlabel=prop:LabelForSuccess
t:parameter name=password
t:label for=password/
t:passwordfield t:id=password value=user.password/
/t:parameter
t:parameter name=passwordagain
t:label for=passwordagain/
t:passwordfield t:id=passwordagain
value=user.passwordagain/
/t:parameter
/t:beaneditform
Thanks a lot.

Re: T5: beaneditform: properties don't get populated although model is bound
partially answering my own question: it doens't happen when both
passwordfields are changed from type: passwordField to type: textField.
Perhaps this is a bug in passwordField?
Kind regards,

Re: T5: beaneditform: properties don't get populated although model is bound
yeah that makes sense.
However, when a user wants to edit his userprofile, I want the password
fields to be filled in. How would I do this using the beaneditform? Is this
at all possible?

how to get the nice ajax form-validations when using beaneditform.recordError()
I get nice ajax validations on fields when using the @Validate-annotation
etc.
I want that as well for cross-field validation, but instead I get the
'general' validation box in red above my form.
I used the following validation-code to check if the two passwords supplied
are the same, and if not record an error to the password field:
Object onValidateForm(){
if(!user.getPassword().equals(user.getPasswordAgain())){
beanEditForm.recordError(password, the two passwords
supplied were not
the same));
}
Does this have to do with the 'ajax-validations' being bounded to a
particular field and the 'general validation' being bound to the form in
general (this is how it seems to me).
Does anyone know how to get the nice ajax-validations on the above
validation as well?
Thanks.

T5: how to add a LinkFactoryListener to the existing linkFactory-service
I'm trying to add a custom made LinkFactoryListener to the existing
LinkFactory-service, but with now success. I must admit I'm really not
fluent with Tapestr-ioc so I think it might me something obvious.
I tried several things, for instance trying to contribute a listener to the
LinkFactory (if it can be contributed to, how do you know for sure? ), but
that doens't work.
building a LinkFactory as a service and adding the built
LinkFactoryListener (see below) doesn't work either error -- Service id
'LinkFactory' has already been defined.
Any suggestions?
Thanks,

Re: getting ClassFactory is matched by 2 services After upgrade from 5.06 - 5.0.11

RE: T5: nested loops don't work (can't figure this one out)
Arghh. Thanks a lot! I missed that. I figured it couldn't be a Tapestry
thing.
I traced back why I thought that the resulting sublist had an element (while
in fact it didn't): apparently a sublist is nothing but a wrapper around the
source-list (which I didn't know_, which is why burried in the debug
parameters the sublist still shows to have an element. Anyhow,
Thanks again.

I have 2 nested loops where the value of the outer loop is used as the

T5: template parser XHTML-well formed -- javascript goes wrong
Hi ,
I have a template which includes a javascript-function:
function asyncCall (){
if(($('quickTextField').value.length 2))
{
new Ajax.Request ('${quickSearchBoxLink}',
{asynchronous:true,onSuccess:handleResponse});
}
}
However, this gets converted to (note the gt; instead of '' (greater than)
:
function asyncCall (){
alert($('quickTextField').value);
if(document.getElementById(quickTextField).value.length gt; 3)
{
new Ajax.Request
('/aanbiedingen.quicknavigation:quickSearchBoxAction',
{asynchronous:true,onSuccess:handleResponse});
}
}
Obviously this is because the template outputs well-formed XHTML.
Still I need to include the function in the template since I need '
${quickSearchBoxLink}' to be translated by Tapestry. How to proceed?
Thanks,
Geert-Jan

Re: T5: Linkage error .... violates loader constraints
As an addition:
also pointing out what type of errors are likely to cause these errors would
help.
I know that mixing injection with components can give loader constraints,
which is why i created an interface for SuperPage. Moreover, I can mimagine
that cyclic references would cause errors as well. Are there any others that
I should track in my code?
Thanks again,

that's because everything worked fine, and after some slight modifications

the setup is not that simple, but here it goes anyway:
- baselayout is a basic layout that wraps all pages as implemented in an
abstract class called superPage.
- all pages extend SuperPage.
- SuperPage implements ISuperPage (for mixing services with components)
- all pages have a quicknavigation component , although their
implementation can be different.
- each quickNavigation-component inherits from AbstractNavigationContainer
(which is where the loader constraint happens)
the relevant parts:

SuperPage (implements ISuperPage)

}
I'm really out of options, as I can't seem to comment enough lines to make
it work: when i comment quicknavigation in baselayout.tml the error
simply shifts to another component that implements
AbstractNavigationContainer
Thanks a lot for any help!

T5: Linkage error .... violates loader constraints
I'm going slightly insane on this one..
that's because everything worked fine, and after some slight modifications

The error I'm getting is this:

- all pages have a quicknavigation component , although their implementation

Re: T5: Linkage error .... violates loader constraints
what do you mean exactly by trying to define a class in classloader ?
I didn't do anything special in creating these instances and just follow the
normal route.
The one thing that may have some, I dont'know : dependency cycle thing
going on is:
SuperPage referencing component quickNavigation
and quickNavigation referencing Superpage by using componentResources to
travere the component-tree upwards.
No sign of double recreating a base-class twice (in one pass)
please keep the options coming,
I will investigate further,

That error can be caused by trying to define a class in classloader which
already contains a class with the same name. I believe that Tapestry does
some magic with the component base classes when it is extending them...
maybe there is something causing Tapestry to try and recreate the base
class
twice?

I know that mixing injection with components can give loader constraints,

that cyclic references would cause errors as well. Are there any others
that
I should track in my code?

t5: violates loader constraints-error when loading pages into ioc-injected class-instance
I created a class PageRegistry and defined it in Spring. I use @Inject to inject the singleton-instance of this class. (This worked before with other classes). in the constructor of PageRegistry I fill a map with page-instances. (So that i can access some methods of a page when I dont have access to a specific instance, ad having static-methods doesn't cut it. ) At that point I get a violates loader constraints-error on component QuickFormAllResults. (A component which is contained by a couple of those pages). What's happing here? Is instantiating page-instances in a ioc-injected class-instance impossible or something?

T5: conditional parameter binding or something
I need a bit of introduction to lay down the problem, so please bare with me:
I have a component which renders lists of items. A parameter (childcounter)
keeps track of the number of rendered items in the current List.
I have the requirement. to be able to define on a per-page basis how many
items are rendered at max. I implemented this by simply binding childcounter
param and checking it against a field (say: maxitems) on the page. Depending
on that I can decide on a per-page basis what to do with items that exceed
the maxitems-threshold. (render different blocks, etc) So far so good.
Currenly Im using this component to render facets
(http://en.wikipedia.org/wiki/Faceted_classification) as part of a
navigation menu. The requirement is to (for each list) render all SELECTED
facets first and then render x (say 5) UNSELECTED facets per list, where x
is defined by maxitems.
The problem:
the component doesn't know (and shouldnt know) that it is rendering facets.
So it doens't know if a facet is selected or unselected. Based on that the
childcounter is incremented each time a selected or unselected facet is
rendered, and the maxitem-treshold is reached when 5 facets per group are
rendered (independent whether they are selected or unselected). Obviously
thats not what I want.
The solution (so I thought)
1. The component doens't know that it's rendering facets, but the page
knows. Moreover, the component outputs the item that it is currently
rendering. (the facet in this case).
2. the param childcounter of the component is bound to the page field
'facetCounter'
since as I understand it a param-binding is bi-directional I did the
following:
Page:
--
@Component(parameters = {result=facetdsText,
row=gGroup,childrow=facet,ulClass=literal:facets,
childcounter=facetcounter})
private CompositeFlexLi facetBlock;
public void setFacetCounter(int facetCounter)
{
if(facet==null || !facet.getFacet().isSelected())
{
this.facetCounter = facetCounter;
}
}
What it does is obvious:
1. the component renders and updates childcounter, which in effect calls
setFacetCounter(int facetCounter), since its bound to facetCounter.
2. facetCounter is only updated when the current item is a UNSELECTED facet
(which it knows in contrast to the component)
The actual problem now is that facetCounter indeed is only updated when a
facet is unselected, but the parameter 'childcounter' is still updated,
although it is bound to the field facetCounter which is not updated (they
aren't in sync).
The behavior now is the following: (say i have 2 selected facets)
childcounter: 1,2,3,4,5
facetfield: 0,0,3,4,5
while i figured it would be:
childcounter: 0,0,1,2,3,4,5
facetfield: 0,0,1,2,3,4,5
Was I expecting to much 'binding-magic' to happen here, or am I missing
something?
If not, what would be your suggestion to tackle this issue? (making the
component aware that its rendering facets is as I explained no option)
Thanks in advance,
Geert-Jan

Re: T5: conditional parameter binding or something
I quickly solved it with some kind of hack for those interested, but I'm
still curious if the kind of binding I described is possible at all.
Cheers,
Geert-Jan
A hack that's working:
introduced 2 extra fields: facetmaxInc and FacetOld;
public void setFacetCounter(int facetCounter)
{
this.facetCounter = facetCounter;
if(facet!=null facet.equals(facetold))
{
facetMaxInc = facetMax;
facetold = facet;
}
if(facet!=null facet.getFacet().isSelected())
{
facetMaxInc++;
}
}
and check on facetMaxInc.

This is what tapestry does:
script type=text/javascript
!--
Event.observe(window, load, function() {
Tapestry.registerForm('form');
Calendar.setup({inputField:a,ifFormat:%d-%m-%y,button:a:trigger,onUpdate:callOnUpdate});
});
// --
/script
what i need:
script type=text/javascript
!--
function callOnUpdate(cal)
{
alert('do something here');
}
Event.observe(window, load, function() {
Tapestry.registerForm('form');
Calendar.setup({inputField:a,ifFormat:%d-%m-%y,button:a:trigger,onUpdate:callOnUpdate});
});
// --

T5: why is a coorcion needed from subclass to abstract superclass?
just curious: why is it needed to make a cooercion from a page subclass to an abstract superclass? Isn't the cast already implictly defined by the 'super-sub relation'?

T5: how to let subclass decide which component to render
I've got a page-class hierachy which all use component BaseLayout as their
layout. This BaseLayout-component contains a component called QuickForm.
Each page-class must render a QuickForm-component but the implementation may
differ (so there is more than 1 actual QuickForm-component.
I started experimenting with the following:
BaseLayout
-
@Component
@Parameter(required=true)
private QuickForm quickForm;
SuperPage
---
@Component(parameters = {page=this,quickform=quickform})
private BaseLayout bl;
@Component
private QuickForm quickForm;
So that he actual quickform can be passed as a parameter from (int this
case) SuperPage to baselayout.
However, then component quickForm in class SuperPage must exist in the
template, which can be done by putting it in a block, (But SuperPage is
just what its called, an abstract base-class ,which doens't have a
termplate, so I must put the block in the templates of all actual
implementations of SuperPage, etc. ,etc. ) Excuse the ranting, but I think
you get the point.
All in all, I don't like this approach at all. Am I missing something here?
Thanks in advance,
Geert-Jan

T5: datefield with custom configure howTO
I subclassed the DateField-component to MyDateField with the purpose to
overwrite the configure-method, since I need a custom method to go off when
I select a date in the calendar.
I did the following in MyDateField: (where onSelect1 is a function defined
in my page).
protected void configure(JSONObject setup)
{
setup.put(onSelect, onSelect1);
super.configure(setup);
}
The problem is that the onSelect1-function is never called, although
according to
http://www.dynarch.com/demos/jscalendar/doc/html/reference.html#node_sec_2.3
this is the correct way of defining a callback function for the
onChange-event of the calendar.
Also, Tapestry seems to generate the client-side code correctly to setup the
calendar:
script type=text/javascript
!--
Event.observe(window, load, function() {
Tapestry.registerForm('form');
Calendar.setup({inputField:mydatefield,onSelect:onSelect1,ifFormat:%d-%m-%y,button:mydatefield:trigger});
Calendar.setup({inputField:mydatefield_0,onSelect:onSelect1,ifFormat:%d-%m-%y,button:mydatefield_0:trigger});
});
// --
/script
Anyone knows whats wrong with this?
Thanks in advance

Re: T5: A component returning StreamResponse?
Not sure if you solved this already, but anyway:
Regarding the exception you got:
Borut Bolčina-2 wrote:
then I get Exception:
Component ui/dialog/JQModalAjax does not contain an embedded component
with
id 'wizardStep1'.
which is true, as I don't have WizardStep1 in my ui/dialog/JQModalAjax.tml
As a workaround it's possible to define Wizarstep1 in a block in
JQModalAjax.tml, like so:
t:block
t:WizardStep1 id=wizardstep1/
/t:block
Since the wizardstep component is included in the block it isn't rendered in
JQModalAjax.tml unless explicitly asked to do so. Now you should be able to
do what you wanted without exceptions.

T5: how to pass a component as a parameter? -- getting unbound errors
a quick background first: I'm creating a component which can display a 'list
of lists'. For flexibility I want to implement this as a composite-pattern
in which a CompositeFlexList-component can render one or more
FlexList-components as it's childs. (CompositeFlexList extends FlexList).
This works well when I define the list-component as @Component in the
CompositeFlexList-component.
However for flexibility I need to extract the FlexList-component-definition
from the CompositeFlexList-component and define it in an enclosing page.
So want i want is this:
page
|[EMAIL PROTECTED](..some config here.,childlist=childlist)
CompositeFlexList
list;
|[EMAIL PROTECTED](some config here) FlexList childlist;
Now CompositeFlexList has the following definition:
@Parameter
private FlexList childlist;
public FlexList getChildlist() {return childlist;}
My problem/question:
although component childlist is entirely defined in the enclosing page, and
this component is bound (???) to field childlist in the CompositeFlexList I
keep getting an unbound error, see below.
Am I missing something, or is it impossible to pass a defined
component-instance as a parameter to another component?
Thanks in advance,
Geert-Jan

[T5]: how to prevent onActivate() from firing with activationcontext
for a page, I have two activation-methods: onActivate() onActivate(Object[] list); when i provide an activation context to the page both methods are called -onactivate() first-. This seems correct behavior according to some forum-posts i've read. However, both methods call a method syncLists() which does a pretty expensive operation (get search results based on the activation context or default if no activation context exists). The problem is that now syncLists() is called twice when the page has an activation-context (based on calling both of the onActivate()-methods). Obviously this is unwanted. However, I can't remove syncLists() from onActivate() (without params), because a page-access without activation-context should call syncLists() as well. so what i need to do is a. have onActivate() not called when an activatecontext exists b. detect in onActivate() that an activationcontext exists and based on that not call syncLists(). c. don't have syncLists() updated on onActivate() but on a change of the page (so before the redirect-after-post) I can't find a way to do A. or B. while C. doesn't seem the best option, because a lot of fields (on the page and in components) would need to be tagged with @Persist to survive setting them on post and then redirecting.

Re: [T5]: how to prevent onActivate() from firing with activationcontext
Thanks, removed the onActivate() without params.
Moreover, i didn't test fully and discovered that on a post onActivate is
called once with the context of the old page and once with the context of
the new page, so it's not always empty the first time. Probably saying the
obvious but anyway.. Only in the latter case should the onActivate result
in update of my lists.
for that i have the following to track the current activation-context
@Persist Object[] params;
now i do:
onActivate(Object[] list)
{
if(params!=list) //actually a method doing a compare on the elements of
the list
{
//handle context
params = list;
}
}
thanks for helping me in the right direction,
Geert-Jan

T5: how to let pojo (no component) have reference to PropertyAccess
I have a helperclass SelectModelRepository which centralizes logic concerning selectmodels which different pages/ components can access. This class needs a reference to PropertyAccess to do some of its work, which normally is available as: @Inject PropertyAccess _access. However, this only works on components and not ordinary pojo's like the one described above (i know... components are pojo's too ;-) I tried passing the PropertyAccess-instance from a component to the SelectModelRepository, but that didn't work because the PropertyAccess-instance is only seen as a proxy since the JustInTimeCreator proxies the class until it is needed. This all results in NullPointer-exceptions when referencing the PropertyAccess-instance form the SelectModelRepository. Is there any way to get a valid reference to the PropertyAccess-instance from my SelectModelRepository-instance? The SelectModelRepository-instance is a singleton, so of course it could be injected through Tapestry-ioc, although i havn't tried tapestry-ioc yet at all though. The trouble is that now it is configured as a Spring-IOC instance with a whole chain of spring-ioc-references to build it. So transferring it to Tapestry-ioc gets a bit messy i guess. If no other solution exists, could you show a simple example of where (what file) and how to configure the SelectModelRepository-instance as Tapestry-ioc service, thanks, Geert-Jan -- View this message in context: http://www.nabble.com/T5%3A-how-to-let-pojo-%28no-component%29-have-reference-to-PropertyAccess-tf4676141.html#a13360247 Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: T5: how to let pojo (no component) have reference to PropertyAccess
Never mind. I thought it would be difficult to define SelectModelRepository in Tapestry-IOC given the existing spring-ioc chain it needs for construction.

Re: how to have persistent data in querystring?
Well i guess the onPassivate-method isn't entirely out of the question since it gives a central place to handle this on the page-level as well. The tagging-variant seems nicer though. I thought i read somewhere in the documentation that a 'client-side persistence strategy' was on the horizon, which would include 'automagically' inserting persistent fields into the url. I can't find anymore where i've read it though. Since we're talking about updating / changing the url, in a somehwat related post i asked about possibilities for rewriting the url. (I havn't found time to try to resolve this) http://www.nabble.com/url-rewriting-in-Tapestry-5-tf4496726.html#a12823397 from that post: For example I want a Venue bean with name venueX and id=123 to show up as: http://test.com/venue/countryname/cityname/venux/123 Notice the countryname and cityname, which aren't fields of the Venue-page but are derived from the association venue-page-- venue-- city -- country. I think adapting the onPassivate-method for inserting these values into the url and onActivate() for only parsing the necessary fields from this url is all that is needed to get this to work, is this correct? btw: a Url-rwrite filtr for this won't work because i also want to have the translation the other way around.: not only from nice -- tapestry internal but also from tapestry internal -- nice. Url-rewrite only gives me the former. Later on i would like to strip the first /venue/ -- http://test.com/venue/countryname/cityname/venux/123 would become http://test.com/countryname/cityname/venux/123. This becomes harder, because tapestry now doesn't know anymore to which page to redirect. out-of-the-box it starts searching for a page with countryname. I guess for this I have to dig a little deeper. Hmm, in hindsight i believe this isn't at all a coherent post, with almost no question or conclusion to be found... consider this a kind of braindump ;-) cheers, Geert-Jan Josh Canfield-2 wrote: Ok, and you want to do this without implementing a passivate method on page B...

You only see the getTheLink method executed once because that

correct link that is returned from your method. This is done once
when the page renders. If you look at the rendered page source
you won't see ${theLink}
there, instead you will the the generated link to your listener.
Anyway, does it really matter how many times the getTheLink
method is invoked ? I think not. What really matters is that the
listener
method to which your getTheLink method should be returning the
URL to is
called whenever you call the sendRequest function.

2. the first time i send a onchange.
However after the first onchange all other onchange-event don't
get
getTheLink() executed, although sendRequest() is called on the
client-side
each time.
This is my relevant code:
in html: script
function sendRequest() {
alert(sendRequest reached);
new Ajax.Request('${theLink}',
{asynchronous:true,onSuccess:handleResponse});
} /script
...
select t:type=select t:model=themaList t:value=thema

System.out.println(catched!!);
return catched!;
}
Do you 've got any idea what causes this behavior?

Re: t5 form submit not fired
thanks for mentioning the difference. In my case a dropdown-change causes a
result-set to reload based on a new query which is shown as the main result
on the page. Since this almost means rendering the entire page again, there
isn't much difference between streaming the diference as Json or whatever or
doing a complete reload. However ,i'm the first to admit that to do things
as populating dropdown boxes (autocomplete or whatever) or changing a
fraction of the page, AJAX is the way to go.
Thanks again,

The whole point of AJAX is not having to return the whole page. You just
want to return the part of the page that needs updating. If selecting a
field in a drop down is supposed to add a dependant drop down (choose a
country changes possible address fields for instance), then you only
return
enough information for that field to be updated and use Javascript to
populate the field.
Your stream response can be XML, JSON, or HTML depending on what your
needs
are...

If you look at the rendered page source you won't see ${theLink}

The nightly builds implementation is adding the client persisted fields into the url as a query parameter using a Base 64 encoded object stream...

I thought i read somewhere in the documentation that a 'client-side persistence strategy' was on the horizon, which would include 'automagically' inserting persistent fields into the url. I can't find anymore where i've read it though. Since we're talking about updating / changing the url, in a somehwat related post i asked about possibilities for rewriting the url. (I havn't found time to try to resolve this) http://www.nabble.com/url-rewriting-in-Tapestry-5-tf4496726.html#a12823397 from that post: For example I want a Venue bean with name venueX and id=123 to show up as: http://test.com/venue/countryname/cityname/venux/123 Notice the countryname and cityname, which aren't fields of the Venue-page but are derived from the association venue-page-- venue-- city -- country. I think adapting the onPassivate-method for inserting these values into the url and onActivate() for only parsing the necessary fields from this url is all that is needed to get this to work, is this correct? btw: a Url-rwrite filtr for this won't work because i also want to have the translation the other way around.: not only from nice -- tapestry internal but also from tapestry internal -- nice. Url-rewrite only gives me the former. Later on i would like to strip the first /venue/ -- http://test.com/venue/countryname/cityname/venux/123 would become http://test.com/countryname/cityname/venux/123. This becomes harder, because tapestry now doesn't know anymore to which page to redirect. out-of-the-box it starts searching for a page with countryname.

I'm still not sure if it's a hibernate or a tapestry thing.
FYI; the error is happening in:

I was on a roll until i wanted to include the name of a City-instance

However, city is of type City and not op type java.lang.Boolean!
The traversal goes through a POI and a City-class which are both mapped as
hibernate-entities.
the traversal poi.getCity() is a lazy association.
(for you hibernate gurus:
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name=cityid, nullable=false)
@Cache(usage =

t:parameter name=groupheader
div style=padding:5px

${firstresult.poi.city.name}
/strong
/div
/t:parameter
/t:compositeBlockList
What is causing this error? Could the hibernate-entity City look like a
boolean (when reflection is used) before it is lazily fetched?? I can't
really imagine that but who knows? anyone?

how to have persistent data in querystring?
okay, I like peristent data very much. On the other hand I want to have pages in which several persistent properties are encoded into the querystring (for better bookmarking and other requirements from a user-perspective). so my question is: is there a way to encode / decode certain persistent properties into the querystring? The best would be a way without having to change the onActivate and onPassivate-methods of course...

template-expansion sees hibernate-entity as java.lang.Boolean?
first of all, excuse me for the post-flood, but I had some standing issues.
Perhaps some of these questions can help others as well so here this one
goes:
I was on a roll until i wanted to include the name of a City-instance
through a template expansion, which gave the error:
Could not convert 'firstresult.poi.city.name' into a component parameter
binding: Class java.lang.Boolean does not contain a property named 'name'
(within property expression 'firstresult.poi.city.name').
However, city is of type City and not op type java.lang.Boolean!
The traversal goes through a POI and a City-class which are both mapped as
hibernate-entities.
the traversal poi.getCity() is a lazy association.
(for you hibernate gurus:
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name=cityid, nullable=false)
@Cache(usage =
org.hibernate.annotations.CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
private City city;
my expansion looks like::
t:compositeBlockList t:id=comp1
t:parameter name=groupheader
div style=padding:5px
strong
${firstresult.poi.city.name}
/strong
/div
/t:parameter
/t:compositeBlockList
What is causing this error? Could the hibernate-entity City look like a
boolean (when reflection is used) before it is lazily fetched?? I can't
really imagine that but who knows? anyone?
thanks,
Geert-Jan

Re: t5 form submit not fired
Yeah i see/know, but for the discussion say that I want AJAX to change a
portion of the page every time a onChange-event fires (the server-side
method CallWhenOnChangeIsFired() should be called through AJAX whenever this
happens ans this method changes sets the necessary fields / performs a
search, etc. )
The example you provided in the example only fires once but I need it to
fire every time a onChange happens. How to do this?
Thanks in advance,

If you look at the rendered page source you won't see ${theLink} there,

Anyway, does it really matter how many times the getTheLink method is

Re: how to have persistent data in querystring?
that would require a lot of manual labor for each and every link. btw: my question relates to T5. Say i had page B injected into page A. I could then initialize page B and return page B from some eventhandler on page A. What I would want to accomplish is that this automatically results in redirecting to page B (as normal) with the difference that the url of page B shows my predefined fields of page B in the url (I know I mentioned querystring in the subjectheader, i mean the path-part of the url) The mechanism could know this because at designtime I could have tagged the fields of page B that I wanted to include in the url. This would enable me to once define these fields at design-time and not having to worry about it later on. is anything like this out there, or planned at all?

t5: mock-up templates with sample-content then replace in t5
Hi,
in T4 it is possible to mock-up pages in your favorite html-editor (say
dreamweaver) including sample-content (for tables for example).
How can I achieve the same in T5.
I mean, I can add a table (see below) with dynamic content, but is it
possible to add sample content (which is replaced by the actual dynamic
content on launch) to this same table definition so that the design aspect
is integrated as well?
Thanks in advance,

[T5]: binding issue: supplying parameter to component -- always null
Hi all,
I guess I'm missing something here, maybe a trival thing so bear with me
please.;-)
I'm trying to extend the T5 grid / griddatasource for my requirements. For
some event-handling in GridColumn I need to reference the field _model of
type BeanModel which exists in the Grid-class from GridColumn. So I both
extended Grid -- LazyConfigurableGrid and GridColumns -- LazyGridColumns.
next,I supplied field _model as a parameter from the gridclass to the
gridcolum-class.
My problem:
_model==null in GridColumn all the time. I guess this is some binding-thing
that I can't quite get my head around. (_model == null on initialization of
the component, but i thought it would be updated later on)
The general question: how to pass objects by reference as parameters, since
they always seem to be null.
the relevant bits:
LazyConfigurableGrid:
@Parameter
private BeanModel _model;
@SuppressWarnings(unused)
@Component(parameters =
{ sortColumnId=sortColumnId, sortAscending=sortAscending,
source=_source, _model=_model })
private LazyGridColumns _columns;
LazyGridColumns:
@Parameter
private BeanModel _model;
Thanks in advance,
Geert-Jan

how to reference public field of included component in template (T5)
Some context first:
I'm using the T5 grid with the row-parameter to bind the current-row to a
property 'cityresult' so that I can edit the contents of all cells of the
name-column (works splendid by the way)
table t:type=Grid row=cityresult source=allCityResults
t:parameter name=namecell
${cityresult.city.name}
/t:parameter
/table
However, I forsee that some pages will contain multiple grids, which would
mean I need multiple binding-properties analogously as 'cityresult' in my
page-class, which clutters my page-class a bit.
At the same time the Grid-component internally has a private field _row of
type Object and a getter (getRow()). Instead of the above I want to be able
to access this field (through the getter or whatever) directly in my
page-template.
So for instance I would end up with:
table t:type=Grid id=allcities source=allCityResults
t:parameter name=namecell
${cityresult.city.name}
/t:parameter
/table
Is something like this at all possible? What needs to be done to make it
possible, or would you discourage it for a particular reason?
Thanks,
Geert-Jan

url-rewriting in Tapestry 5
Hi all, I'm looking for a way to have flexible / nice urls when using tapestry5. I know that with tapestry 5, supplied parameters are appended to the path instead of to the querystring, but i'm looking for a bit more control. For example I want a Venue bean with name venueX and id=123 to show up as: http://test.com/venue/countryname/cityname/venux/123 Notice the countryname and cityname. Anybody knows if this is possible with Tapestry 5 out of the box (Can't get my head aroundthis) or with a urlrewriting filter or something? Thanks in advance for any help, yours sincerely, Geert-Jan -- View this message in context: http://www.nabble.com/url-rewriting-in-Tapestry-5-tf4496726.html#a12823397 Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: url-rewriting in Tapestry 5
Thanks these all seem valid approaches. What i'm looking for is a stretching the possibilities i guess but here it goes anyway: I want a way in which I can plug a 'rewrite strategy'. This means that not only I have to translate urls from 'nice' to 'tapestry5' -internal but also the other way around, so that tapestry-pages reference other pages automatically by their 'nice' -url. I would like to keep the code in 1 place for making this bidirectional-translation. Doing this with mode_rewrite does't give me control in code I think. I wonder if this is possible using some form of rewrite-filter, that is able to translate both ways. any ideas on this? regards, Geert-Jan Robin Helgelin wrote: On 9/21/07, Daniel Leffel [EMAIL PROTECTED] wrote: I went down this path and decided that mod_rewrite is a much cleaner way to achieve something like this. Or maybe an urlfilter bundled with your war, there are a few usable ones. -- regards, Robin - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- View this message in context: http://www.nabble.com/url-rewriting-in-Tapestry-5-tf4496726.html#a12825612 Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
