[jira] Commented: (TAPESTRY-1556) EventConnectionVisitor is
sometimes not wired properly
[ https://issues.apache.org/jira/browse/TAPESTRY-1556?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12572554#action_12572554 ]
Daniel Kleine-Albers commented on TAPESTRY-1556:
------------------------------------------------
I had a similar problem some months ago. Here's the scenario I was having trouble with and posted to the ML (http://mail-archives.apache.org/mod_mbox/tapestry-users/200708.mbox/%3cA7244006-EA35-4AED-9147-AA4A6A0BA239@dka-edv.net%3e):
Component C has a form in it that contains a Suggest component. An EventListener is attached to that suggest field (on the onblur event). I found out that I needed to specify the submitForm parameter for this event listener to actually get the form data submitted.
C is embedded in pages A and B. As long as I turn off caching everything works fine. As soon as I turn on caching and access only page A everything's fine as well, but as soon as I access page B after page A has been accessed (also if not triggering the event) I get the following Exception (also happens if accessing A after B so I exclude a problem with this particular page):
No component found in tree for EventListener binding with a matching component id of A/$component...C.
The whole stacktrace follows below. I've searched the archives and found some references that this behavior might be solved if I use an explicit component specification (instead of using annotations) - so I tried that but it didn't make a difference.
What I think is strange is that it searches a component on Page B which has actually its component id prefixed by the name of Page A - this sounds a bit like some variables not getting recalculated correctly when borrowing the component from the pool.
Here's the complete error and stack trace:
No component found in tree for EventListener binding with a matching component id of ValidateEmail/$CPublicBorder.$CRegistration.registrationForm.

> Key: TAPESTRY-1556
> URL: https://issues.apache.org/jira/browse/TAPESTRY-1556
> Project: Tapestry
> Issue Type: Bug
> Affects Versions: 4.1.1
> Reporter: Lionel Touati
> Assignee: Jesse Kuhnert
> Fix For: 4.1.6
>
>
> The method wireElementFormEvents is sometimes broken. When comparing listener.getFormId() to f.getId(), get different results. Sometimes the ids for the same page, same component the id match, but after a tomcat restart, the ids won't match as getFormId returns the form extended id rather than the local one.
> I've changed the method to :
> void wireElementFormEvents(EventBoundListener listener, IComponent component, IComponentSpecification spec)
> {
> if (listener.getFormId() == null)
> return;
> if (_forms.size() < 1)
> discoverPageForms(component.getPage());
> IForm form = null;
> for (int i=0; i < _forms.size(); i++) {
> IForm f = (IForm) _forms.get(i);
> if (listener.getFormId().equals(f.getExtendedId()) || listener.getFormId().equals(f.getId())) {
> form = f;
> break;
> }
> }
> // couldn't find the form they specified
> if (form == null)
> throw new ApplicationRuntimeException(PageloadMessages.componentNotFound(listener.getFormId()), component, component.getLocation(), null);
> String idPath = form.getExtendedId();
>
> listener.setFormId(idPath);
> _invoker.addFormEventListener(idPath, spec);
> }
