Do you mean an implementation of ComponentClassTransformWorker2?

Re: child component lookup
Well, this is actually quite straightforward approach. However I have
encountered a problem that looks weird. This is my mixin code:
*public* *class* ModalIntegration {
@InjectContainer
*private* Form form;
*void* afterRender ( MarkupWriter markupWriter ) {
markupWriter.attributes ( "data-submission-failed", form.getHasErrors
() );
}
}
It's supposed to render an additional form attribute which modal JS later
can use to determine if it should dismiss or not.
Somehow this attribute is being rendered not on the form itself, as I
naturally expected, but on the form's parent element (containing zone).
Is there any explanation for that? I'm using 5.4-beta6.

Re: child component lookup
Pavel, thanks! My point is to handle this on modal level: this should be completely transparent for the form itself.

Re: child component lookup
Ilya, greetings. As for submit button i search inside modal body for form component or specify form name in modal component. So, after clicking button form submits. Onsuccess i invoke hideModal function(via hidemodal event). OnFailure i do nothing except updating formzone to show messages/errors e.t.c. If you want i can send you some examples.

Re: child component lookup
I'm not exactly sure I understand the requirements but I think you could do this with a mixin on the form. At the very least this would allow communication with the form mixin and the modal via the Environment service. The modal could put something in the environment and the mixin could add some status. No status means no form. The mixin could be applied to all forms via a worker.

child component lookup
Is there any way to search for specific component down the component hierarchy? Consider the following use case: - I have a component responsible for rendering Bootstrap modal - this modal may (or may not) contain a form - if modal contains a form and submission is successful, the modal should be automatically dismissed - it modal contains a form and submission is unsuccessful, the modal should not close (regardless of client validation being on/off) I've been looking around ComponentSource/ComponentResources classes, but couldn't find anything relevant yet. Environment service can't help either, because modal is a form's parent and at the time of modal rendering FormSupport is not yet available. -- Ilya Obshadko
(solved ?) tapestry 4.1.6 and pergmen question
I write this so it goes on web archives and maybe (even though is not probabile) one day someone will find it useful. The solution is to avoid this https://wiki.apache.org/tapestry/EasyBrowserRedirection never raise that exception. Instead use PageRedirectException in case you want to pass parameters to the page put them in the session and remove them in rendering phase of the page you are redirecting to finally be sure PageRedirectException also in the the page you are redirecting to because it will not be trapped an Tapestry Exception page will be showed. --- It seems I have found the glitch. Following this suggestion https://wiki.apache.org/tapestry/EasyBrowserRedirection I had implented redirection in a pageBeginRender method (I'm talking about T 4.1.6, sorry about that) Now it seems that when the excpetion is raised PermGen occupation is increased. It seems there is a difference with this regard raising the exception in a listener instead that in pageBeginrender. Anyone feels its memory activated on this?
