[T5] Re-inject or inherit services in children ?
Hello ! My project is a little more advanced, so I spent some time refactoring the code. Along this refactoring, I saw that I have a lot if component and class that inherit a base page (yes, that's why I have a base page ;). I inject on this page some quite common services (for example, an authorization service). So, what is the best pattern, in regard of Tapestry 5, for a page or component that extends my page base : inject (again) the services, or get it from the parent (what suppose that these services have matching getter in the base page). I believe injection is cheap, but a base page is here to provide common services, so I'm prone to choose the inherit pattern.

Can't get component inside a component
Hi, I'm a newbie in tapestry
I have a component Drapeau that embed 3 others components of type Couleur
all the Couleur components in any phase of the Drapeau render process
appear to be null in my debugger.
Drapeau.html
==
span xmlns:t=http://tapestry.apache.org/schema/tapestry_5_0_0.xsd;
This is a flag
t:Couleur id=couleur1 Couleur 1 /t:Couleur
t:Couleur id=couleur2 Couleur 2 /t:Couleur
t:Couleur id=couleur3 Couleur 3 /t:Couleur
t:body/
/span
Drapeau.java
==
public class Drapeau {
@Component(id=couleur1)
Couleur couleur1;
@Component(id=couleur2)
Couleur couleur2;
@Component(id=couleur3)
Couleur couleur3;
@BeforeRender
public boolean beforeRender(MarkupWriter writer){
return true;
}
... other phases ...
}
And in my page Root.html
t:Drapeau bla /t:Drapeau
The Drapeau is rendered fine (I mean with the three Couleurs) in the
browser but I really don't see how the Drapeau Component can collaborate
with the Couleur components.
Thanks.

Re: Can't get component inside a component
Hi Michael, Thiago is right, first make the fields private... you should have some warnings in your console tough. then you have to decide how you want to add components: you can add components to a page by declaring them in the template like you did (then you dont need to declare them in your page/component class): t:pagelink/t:pagelink or by using invisible instrumentation by adding an t:id attribute to one of your HTML elements that matches a field in the page class/componen class with a @Component annotation with the same name of with a id parameter: a t:id=page.../a // id matches field name @Component private PageLink page // id in template does not match field name @Component(id=page) private PageLink pageToEdit g, kris Thiago HP [EMAIL PROTECTED] 06.12.2007 12:31 Bitte antworten an Tapestry users users@tapestry.apache.org An Tapestry users users@tapestry.apache.org Kopie Thema Re: Can't get component inside a component Try replacing @Component(id=couleur1) Couleur couleur1; by @Component(id=couleur1) private Couleur couleur1; AFAIK, @Component and @Inject only works in private fields.

Re: [T5] Re-inject or inherit services in children ?
I've found that, quite often, there's a little bit of processing
around the injected service method invocation, so that's where the
base page can really add some value: collect and pre-processing the
values before invoking the method.
For example, I was just working on PageLink and ActionLink and
refactoring out an AbstractLink:
public abstract class AbstractLink
{
@Inject
private ComponentInvocationMap _componentInvocationMap;
/**
* An anchor value to append to the generated URL (the hash
separator will be added automatically).
*/
@Parameter(defaultPrefix = LITERAL_BINDING_PREFIX)
private String _anchor;
@Inject
private ComponentResources _resources;
private final String buildHref(Link link)
{
String href = link.toURI();
if (_anchor == null) return href;
return href + # + _anchor;
}
/**
* Writes an lt;agt; element with the provided link as the href
attribute. A call to
* [EMAIL PROTECTED] org.apache.tapestry.MarkupWriter#end()} is emnot/em
provided.Automatically appends
* an anchor if the component's anchor parameter is non-null.
Informal parameters are rendered as well.
*
* @param writer to write markup to
* @param clientId value written as the id attribute
* @param link the link that will form the href
* @param namesAndValues additional attributes to write
*/
protected void writeLink(MarkupWriter writer, String clientId,
Link link, Object... namesAndValues)
{
Element e = writer.element(a, href, buildHref(link), id,
clientId);
writer.attributes(namesAndValues);
_resources.renderInformalParameters(writer);
_componentInvocationMap.store(e, link);
}
/**
* Used for testing.
*/
void inject(String anchor, ComponentInvocationMap map,
ComponentResources resources)
{
_anchor = anchor;
_componentInvocationMap = map;
_resources = resources;
}
}
This approach simplified PageLink andActionLink and totally hid the
ugly ComponentInvocationMap (that is, we didn't have to re-inject it
into subclasses, or provide a protected getter method).
I kind of think that if you can't find a true purpose for the base
class beyond a convienient place for the common injections, then
perhaps you are on the wrong track. I kind of like the list of
injections in my components ... it's kind of like a cast of characters
in a play.
Another option is to create a facade service that wraps around the
many services your application needs, so that just a single facade,
rather than many individual services, can be injected. Again, this is
an alternative to a base class.

Re: T5: Anyone using PageTester?
Howard, I'm using PageTester as well so be warned and don't break things. I think this habit of yours of breaking things you think should be done differently is bad indeed. It is this habit that had endured sufferings and almost an impossible task for anyone trying to migrate from any pre T5 to T5. I heard there is a secret work on T6 that would be almost incompatible with all previous versions. Why do you always have to re-invent the wheel? I hope you would one day learn from the decent open source projects out there like Spring and Hibernate. These guys are geniuses! They take on the challenging task of remaining backward compatible while providing great new features instead of always choosing the easier and trivial path of starting afresh, like you've demonstrated so far with any major release of Tapestry.

Well, now that you explain me that, I think it's my problem. I almost only use the base page/component as a container for common services/logic. But as you said, it should be better suited to create new services than a base page for that, and only use them where they are needed. I kind of like the list of injections in my components ... it's kind of like a cast of characters in a play. And I completely agree with that. In each component, I use a really visible comment to hilight the injected services : just with that, I can (almost) know what the component is going to do, or at least what may be its side effects. So, it's a really good reason to inject services every time they are really need. Ok, so I should build more unit services, make some facade for logically linked services... Well, just really use the power of Tapestry services ;) Thank you really much for the advices, and I believe I'm going to remove this needless base page :) -- Francois Armand Etudes Développements J2EE Groupe Linagora - http://www.linagora.com Tél.: +33 (0)1 58 18 68 28 --- InterLDAP - http://interldap.org FederID - http://www.federid.org/ Open Source identities management and federation - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Tapestry EventListener doesn't seem to submit form
Hi,
I'm using Tapestry 4.1.3 (integrated in Appfuse 2.0.1) and the
@EventListener functionality. The eventlistener method is called correctly,
but I can't get any user-entered values from the form. As I understood from
the documentation, the form should submit itself by default and send the
values to the server, but it doesn't work for me. I tried to use @Persist
annotation for the getter of the requested value, but it didn't help.
input jwcid=@TextField value=ognl:recName id=recName
class=text large type=text /
@Persist
public abstract String getRecName();
@EventListener(events=onchange, elements=recName)
public void onRefresh(IRequestCycle cycle) {
log.debug(getRecName()); // this returns null (or initial value)
}
I presume that the getRecName() function in the EventListener is supposed to
return the value entered by user - is it right? Am I doing something wrong?
Thanks

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?

Re: Tapestry EventListener doesn't seem to submit form
Using elements=elementId only targets and listens to dom nodes.
You only get the majority of automated functionality (like submitting
forms) when you target a component via
targets = componentId
Change your example to be:
input jwcid=[EMAIL PROTECTED] value=ognl:recName id=recName
class=text large type=text /
@EventListener(events=onchange, targets = recordName)
public void onRefresh(IRequestCycle cycle) {
log.debug(getRecName()); // this returns null (or initial value)
}
and it should work..
p.s. Internet explorer doesn't do a very good job of reporting changes
to textfields via the onchange event, please see the related
quircksmode links and warnings on the bottom of the documentation page
for @EventListener for more on this..

T3: PropertySelection
Hello,
I'm having issue with PropertySelection in a Form.
I'm using one page to add and update. Data entry fields of the form gets
changed according to the property selection during add. For example if
infType=DOG selected then the form displays only dog specific fields and if
infType=PAK then the form displays only parking specific fields. All these
works fine.
The problem is when I try to update the record. The form fields are not
displayed accordingly to the infType. If I reselect the item from the
PropertySelection then it shows the fields properly.
I couldn't figure out how to execute the submitOnChange automatically in
pageBeginRender.
If any one help me on this would be very helpful.
public void pageBeginRender(PageEvent event) {
this.userLoggedIn =
AuthorisationUtil.getNormalisedRemoteUserName(event);
if (!getNewInfringement() !event.getRequestCycle().isRewinding()) {
//execute the submitOnChange automatically
}

[T5] Message Page Redirect
Hi All, I'd like to build a component/page that handles a page redirection. An example situation is when a user may try and access page X but due to permissions levels may not be allowed access (or some other reason) so they are presented an intermediate page with some message like You do not have permission to access this page and then are redirected to another page (i.e. the previous page). In my current implementation I pass on a simple string for the logical name of the page to be redirected to but this doesn't work too well when I have pages that require context elements and I don't know all the information to pass on as a string. So what kind of object should I be working with instead? and does it have a toString() method in order to convert it to a logical name that can be embedded into the html meta tag (i.e. meta http-equiv=refresh content=3;/MyApp/Page1/context). Thanks for any help! Jean-Philippe
T4.1.3 fails with javassist errors after running awhile
After running fine for a while (I can access it for a hour), my application
stops functioning and starts failing with the exception below.
It appears that javaassist is not able to find my abstract page classes that it
has compiled.
My versions:
ognl-2.7.1.jar
javassist-3.4.ga.jar
tapestry-annotations-4.1.3.jar
tapestry-contrib-4.1.3.jar
tapestry-framework-4.1.3.jar
I read all the posts related to this topic, but I thought it was a 4.1.2
problem, but I am running the 4.1.3 version. I am using the same
ognl/javassist versions as the tapestry 4.1.3 pom.
Thank you for any pointers.

Re: t5: violates loader constraints-error when loading pages into ioc-injected class-instance
If you need a page instance, you need to go through the appropriate Tapestry services ... unfortunately, some of them are internal. Nonetheless, Tapestry enforces a specific lifecycle on Tapestry pages and components and if you attempt to instantiate them directly you will fail. If you have common logic, put it in services, not on pages if at all possible. That's what the IoC container if for. Pages should be thin layers between the world of HTML and HTTP and the world of services (whether T5 IoC, Spring or other).

Re: T4: replacing script asset in AbstractSubmit
Hi, so, SubmitBindings.script actually calls tapestry.form.submit and/or tapestry.form.refresh, tapestry.form.cancel so, why not just connect around those and do whetever you want? You can completely bypass them, or just have your code run before or after those... BTW, I remember someone doing something similar some time ago using http://tapestry.apache.org/tapestry4.1/tapestry-contrib/componentreference/ajaxstatus.html and overlaying on top of everything... i would be interested in finding out more about your implementation, esp. some code :) On Dec 3, 2007 11:30 PM, Steve Shucker [EMAIL PROTECTED] wrote: Is it possible to globally replace the SubmitBindings.script file used by all the AbstractSubmit subclasses to wire up ajax events with my own version? I've got a script that imposes an overlay on top of the components being updated and prevents double-clicks. Right now, I can wire it up to each individual button with a @Script, but it would be cleaner if I could just replace the asset where the submit script is wired. That way it would be automatically applied to all ajax submits. I'd like to do this without hacking up my tapestry jar. It might be nice to disable or unwire non-ajax submit buttons when they're clicked as well, but I haven't tried implementing that yet. -Steve - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- Andreas Andreou - [EMAIL PROTECTED] - http://blog.andyhot.gr Tapestry / Tacos developer Open Source / JEE Consulting - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: [T4] Help converting InjectComponent annotation to page specification
Hi,
i'm not exactly sure how you're going to use that client id,
but if you really want to get rid of annotations, why not just try:
public String getRowClientId() {
return getComponent(customersLoop).getClientId();
}
On Dec 4, 2007 2:20 AM, cpnguyen [EMAIL PROTECTED] wrote:
Hi all,
I'm a newbie at Tapestry and I'm reading Kent's book trying to get Tapestry
to work with AJAX.
In one of his examples, he has a customerCRUD.java class with the following
annotation:
@InjectComponent(customersLoop)
public abstract ForBean getRow();
public String getRowClientId() {
return getRow().getClientId();
}
This method will return the HTML id for the current tr element generated
from a For loop component.
I am having issues getting this to work with my current project and I want
to move annotation specification to page file specification. What is the
equivalent page specification syntax for the above?
From Tapestry's annotation reference:
The InjectComponent annotation allows nested components to be injected as
read-only properties. It is attached to an accessor method:
@InjectComponent(inputUserName)
public abstract TextField getUserInput();
This is functionally the same as providing the property attribute of the
component element.
So I tried the following:
component id=customersLoop type=For property=row
binding name=source value=customerEntries/
binding name=value value=customerEntry/
binding name=index value=idx/
/component
property name=rowClientId initial-value=row.clientId/
THEN
bean name=rowClientId class=java.util.String property=row.clientId/
and other variations without any luck.
What am I doing wrong? TIA!
