Re: T5: FileUpload and time out
Hi,
probably I did not make my original question clear, the UploadExample works,
however, there are situations that we got a time out exception, how to track
this exception in the following example? thanks for the help,

Hi, I'm working with Tapestry 4.1.1 and I'm using client side validation. Is it possible to specify the background color of the dialogUnderlay div somewhere? Kind regards, Nils
Re: AW: AW: AW: AW: Strange behavior of special characters
Thank you i will have a look at this. At the moment we don't have the time to deal with this problem, but since yesterday we have a clue what is the problem and probably will be able to resolve this next few days. I will inform you when i can say exactly what went wrong. Andreas Andreou wrote: Try searching the bug tracker... I found http://issues.apache.org/jira/browse/TAPESTRY-607 'Output encoding problem with some versions of Tomcat 5' (btw, what's your servlet container?) and some others that may help...

I think it used the ending of the file name of the property to determine the indended encoding allowing you to use UTF-8 and be done with it...

To this problem you mentioned concerning Java Properties Files and UTF-8 encoding i just can guess, that it seems that this problem doesn't inflict the usage of properties inside tapestry.

Re: [T5] Rendering a block a component received as parameter
Hi Josh,
thanks, this works great!
I think I understand the rendering process now a little bit better, so a
Delegate would have been fine too - thank you, Howard. I just didn't
understand how to render that Delegate before, since it is a component
too. (I hope I now understand it correctly that I just would've put it
in the Template and set the Block which should be rendered in
beforeRenderTemplate.)

Josh Canfield schrieb:
I don't recall if you can use MarkupWriter to write blocks yet, but one
method I've used is to return the block from the beginRender method, it's
rendered after whatever you write within the method. I believe for both
blocks you would have to use both beginRender and beforeRenderTemplate, or I
suppose you could loop from the beginRender method.
If you want to wrap your blocks in an element you would start it in
beginRender and finish it in afterRender...
In the case you've laid out though, it might be easier to just create a
template.

[T5] Read informal parameters
Hi everyone, is there any way to read the informal parameters a component received? componentResources.getBlockParameter makes it easy for blocks - but how can I do it with strings, for example? Furthermore, is there maybe any way to get a list of the informal parameters? I looked in the source code and and InternalComponentResourcesImpl implements all what I need -readParameter, getBinding, getInformalParameterBindings- but they are not being published in the Interface ComponentResources. Am I looking in the wrong place or is there simply no other way than to use InternalComponentResourcesImpl - which, of course, I would rather like not to? - Tobias - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Routing and REST
Greetings, I am new to tapestry and I have a few questions about what is and is not possible within the Tapestry framework. Im helping to spearhead a new project for my company to determine the feasability and cost of a new platform for our product. Tapestry seems like a perfect fit for the UI level but a couple of things are holding me back from serving up the Kool-Aid :). I'm not looking for technical handouts, just an assurance that tapestry will not bind me and maybe a point in the right direction. Our product runs as a SAAS but maintains the ability to feel different for different clients and so serves as a portal. We also need to keep costs down on things like SSL certs domain names. You can think of each client as being in a Silo. So the URL standard embeds the silo name as the first directory in the path: http://www.SaaS.com/ClientsName/TapestryStartsHere.html It's not apparent to me that tapestry will allow me to do this within it. I might be able to do it with a Apache mod but I would rather not do that. THe ClientName would need to exist for every request and would tie into just about everything. The other piece I need that's somewhat related is that I want to be able to expose RESTful web services as part of the same system. So while right now I can go to: http://www.SaaS.com/ClientsName/CreateUser/ to get a user form I also want http://www.SaaS.com/ClientsName/CreateUser/JSON/ to access the same service as a REST web service using JSON or XML or just GET and POST params. Would this just require some custom components? and can I access and manipulate HTTP state and return codes from within Tapestry? Thats it!

[T5] Semi static content
Hello all again!
I'm trying to do a simple content management system.
The point is, the system I'm working on has many semi-static pages.
The designers do the contents, and a little bit is dynamic, something like:
h1Sample Page/h1
Blablabla blabla ${currentTime} blablabla
And there are many of this pages.
As dynamic content is minimum, I don't think it's necessary to make all
of this .tml pages with their own classes. So I'm trying to do
only one .tml page (Dynamic.tml with Dynamic.java).
This class will receive a parameter, so on onActivate method he will know
wich page to render.
void onActivate(String page) {}
The problems start here.
How can I mix the Dynamic.tml with another .html contents page?
AND in way that ${tags} in .html files are properly rendered (it will look
for
getTags(), not print ${tags} as it is).
Any ideas?

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.
my code:
//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
{
if (req.isRequestedSessionIdValid()
globals.getHTTPServletRequest().getCookies()==null)
{
Session session = req.getSession(false);
if (session != null) session.invalidate();
HttpServletRequestWrapper wrappednRequest = new
HttpServletRequestWrapperOwn(globals.getHTTPServletRequest());
HttpServletResponseWrapper wrappedResponse = new
HttpServletResponseWrapper(globals.getHTTPServletResponse())
{
public String encodeRedirectUrl(String url) {
return url; }
public String encodeRedirectURL(String url) {

Re: Routing and REST
Currently the logic necessary to do what you want is part of Tapestry internals (non public, subject to change). I would approach this problem using an override of the LinkFactory service (internal) combined with an in-Tapestry filter to extract the client name from the URL and perhaps a little extra work to replace the default component action and page render dispatchers. I would call that journeyman to master level work, not something a total beginner should try to attempt. There are other options, such as bringing in a Tapestry expert to help out on this aspect.

Re: Routing and REST
This request sounds a little open ended, and I think you can do everything you need with Webapp Filters and Tapestry Filters/Services, you just have to spend the time to learn them and think outside the box a little bit. Our project is using T5 for Facebook and OpenSocial applications so there are lots of weird customizations we have to do, and we serve up a semi-unique application per sports team ( all from the single webapp ). So in one way or another, I bet we employ the techniques you would want to employ. - not sure what you mean by multiple clients but: 1) We map the webapp to the root (/) context. 2) We use a normal Webapp Filter to pull out the first directory path from the url and make that the new context (request.getContextPath().. etc etc ), and capture that to determine which sports team we're going to be serving up. - as for the JSON casting, you're saying that any url would have a normal html representation and a json representation, but how different are they? 1) You can easily create a Tapestry Dispatcher that matches and handles any url ending with /JSON/. You can implement all json as unique services that the primary dispatcher would call depending on the incoming url ( you could configure it using some sort of map).. Or you can even copy what the PageDispatcher does and render another unique page (maybe /json/PAGENAME), if you want to use tapestry pages to generate the json. This page could then return a JSON object back to the dispatcher somehow ( maybe setting a request attribute ), which the dispatcher can pickup and spit out to the client...

Im helping to spearhead a new project for my company to determine the feasability and cost of a new platform for our product. Tapestry seems like a perfect fit for the UI level but a couple of things are holding me back from serving up the Kool-Aid :). I'm not looking for technical handouts, just an assurance that tapestry will not bind me and maybe a point in the right direction. Our product runs as a SAAS but maintains the ability to feel different for different clients and so serves as a portal. We also need to keep costs down on things like SSL certs domain names. You can think of each client as being in a Silo. So the URL standard embeds the silo name as the first directory in the path: http://www.SaaS.com/ClientsName/TapestryStartsHere.html It's not apparent to me that tapestry will allow me to do this within it. I might be able to do it with a Apache mod but I would rather not do that. THe ClientName would need to exist for every request and would tie into just about everything. The other piece I need that's somewhat related is that I want to be able to expose RESTful web services as part of the same system. So while right now I can go to: http://www.SaaS.com/ClientsName/CreateUser/ to get a user form I also want http://www.SaaS.com/ClientsName/CreateUser/JSON/ to access the same service as a REST web service using JSON or XML or just GET and POST params. Would this just require some custom components? and can I access and manipulate HTTP state and return codes from within Tapestry? Thats it! Thank you all so much for your time I really like tapestry so far and would love to put my mind at ease and get to coding.

All the jsessionid functionality is provided by the servlet container,

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

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?

is there any way to call from actionlink to call submit from the FORM?
thank you.
You can either submit the form, or follow the actionlink. If you want the
action to be performed when the form is submitted then add the
functionality/method call to one of the form event handlers.
Then you can use prototype's Event to watch for a click on the link and
submit the form.
a href=# id=toolbarSave img src=images/saveRecord16.png //a
t:form t:id=YOUR_FORM_ID t:zone=zoneFormView
...
input type=submit t:type=submit value=submit
/t:form
script
Event.observe('toolbarSave', 'click', function()
{$('YOUR_FORM_ID').submit(); return false;});
/script
I didn't run this, so you might need to play with it to make it work.

Re: T5: what part of tapestry adds Jsessionid
What most people do is to use a normal Webapp Filter to strip jsessionid
from ever being added to the urls..
If you override the HttpServletResponse.encode*Url methods to simply
return the url and not let the container add the jsession id to it.
This means that sessions will only work for users with cookies, but then
again who has cookies turned off these days?

Re: T5: what part of tapestry adds Jsessionid
I had a similar issue with my site and instead took the route of not
creating the session for users that don't need it.
I had to override the tapestry Form component so it only stored the
validation tracker when there were errors and implement a session
persistence that didn't create a session if the value stored was null. I
believe the last part has been fixed in the standard session
persistence. I'm in 5.0.11.
here's my extended Form if you're interested.
public class Form extends org.apache.tapestry.corelib.components.Form {
@Persist
private ValidationTracker _tracker;
private ValidationTracker _nonPersistedTracker;
public ValidationTracker getDefaultTracker() {
if (_nonPersistedTracker == null) {
if (_tracker != null) {
// _tracker is loaded via injection magic when it's in the
session
_nonPersistedTracker = _tracker;
} else {
_nonPersistedTracker = new ValidationTrackerImpl();
}
}
return _nonPersistedTracker;
}
public void setDefaultTracker(ValidationTracker defaultTracker) {
_nonPersistedTracker = defaultTracker;
}
protected void onAction() {
if (_nonPersistedTracker.getHasErrors()) {
_tracker = _nonPersistedTracker;
} else {
_tracker = null;
}

Re: Displaying image on T5 page
Hi Yeeswar, I recently had exactly the same requirement, and solved it in the same way referenced in the wiki page. So then I rewrote my solution as a DisplayChart component, which takes a chart as a parameter and handles the rest of the work for you. A few notes/comments, though: 1) In my case, the chart wasn't generated from parameters in the url, per se. So I initially had problems with the browser caching the chart image because even though the chart had changed, the url was the same. I solved that issue by generating an identifier key for the chart that ensures that different charts get different urls. 2) I create the byte array outside of the StreamResponse. That way I can set the content length (and any other properties I want) in prepareResponse 3) The Wiki article uses jpeg compression. PNG is better for charts, and just as easy to do with the JFreeChart API. If you're interested in my DisplayChart code, write me off list and I'll send it along.

Re: T5: what part of tapestry adds Jsessionid
Just turn your ServletFilter into a RequestFilter.
You can use ApplicationStateManager in RequestFilters now.
(See, for example:

That's why I think it has to do with some internal tapestry
processing.
Do you have an idea where to look?

I'm trying to strip the jSessionId from displaying in the url if:

I implemented a Dispatcher (the last in the line before onActivate

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

Apperantly somehow the jsessionid is picked up anyway although (when

T5: RequestDispatcher to include Tapestry5 Pages
Trying to include Tap5 pages from another J2EE War Servlet/JSP. Using RequestDispatcher to include the tapestry5 page. It keeps complaining that the tap5 page does not exist. If I try the same URL in browser, it works fine. There were some threads in the forum about this. But nothing worked. (tried dispatcherINCLUDE/dispatcherdispatcherFORWARD/dispatcher in the t5 filter mappings in web.xml) Any solutions would be greatly helpful in moving to Tapestry 5. -- View this message in context: http://n2.nabble.com/T5%3A-RequestDispatcher-to-include-Tapestry5-Pages-tp472602p472602.html Sent from the Tapestry Users mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: T5: what part of tapestry adds Jsessionid
Tha's an interesting route, ill have a look at it, Thanks.

I had a similar issue with my site and instead took the route of not
creating the session for users that don't need it.
I had to override the tapestry Form component so it only stored the
validation tracker when there were errors and implement a session
persistence that didn't create a session if the value stored was null. I
believe the last part has been fixed in the standard session
persistence. I'm in 5.0.11.
here's my extended Form if you're interested.
public class Form extends org.apache.tapestry.corelib.components.Form {
@Persist
private ValidationTracker _tracker;
private ValidationTracker _nonPersistedTracker;
public ValidationTracker getDefaultTracker() {
if (_nonPersistedTracker == null) {
if (_tracker != null) {
// _tracker is loaded via injection magic when it's in the
session
_nonPersistedTracker = _tracker;
} else {
_nonPersistedTracker = new ValidationTrackerImpl();
}
}
return _nonPersistedTracker;
}
public void setDefaultTracker(ValidationTracker defaultTracker) {
_nonPersistedTracker = defaultTracker;
}
protected void onAction() {
if (_nonPersistedTracker.getHasErrors()) {
_tracker = _nonPersistedTracker;
} else {
_tracker = null;
}
}

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.

Re: [T5] is there any way to use actionlink to call submit from outside of FORM?
thanks for your reply. I will try it out :)

thank you.
You can either submit the form, or follow the actionlink. If you want the
action to be performed when the form is submitted then add the
functionality/method call to one of the form event handlers.
Then you can use prototype's Event to watch for a click on the link and
submit the form.
a href=# id=toolbarSave img src=images/saveRecord16.png //a
t:form t:id=YOUR_FORM_ID t:zone=zoneFormView
...
input type=submit t:type=submit value=submit
/t:form
script
Event.observe('toolbarSave', 'click', function()
{$('YOUR_FORM_ID').submit(); return false;});
/script
I didn't run this, so you might need to play with it to make it work.

T5 - Javascript libraries on ajax requests
Hello,
I have a zone that is updated with an ajax request. Inside this zone, I use
an InPlaceEditor components (from t5components) many times (one for each row
in a table). The InplaceEditor component include a javascript library,
controls.js, with the IncludeJavascruptLibrary annotation.
On the first request, this works ok, because even when the InPlaceEditor is
used many times, control.js is included just once. But when I update this
zone element and many other InPlaceEditor's arrived, this request comes with
many requests for including control.js. The JSON response when I update the
zone is something like this:
{scripts:[/assets/scriptaculous/5.0.14-SNAPSHOT/controls.js,/assets/scriptaculous/5.0.14-SNAPSHOT/controls.js,/assets/scriptaculous/5.0.14-SNAPSHOT/controls.js,/assets/scriptaculous/5.0.14-SNAPSHOT/controls.js],
I'm doing something wrong? Or T5 doesn't check that a library is included
more than once in ajax requests??
Regards.
