togglePanel and problems during Ajax ReRender

[speleomaniac]

Hi everybody,

I am having problems with togglePanel but may be I am also pushing borders of what is possible..

I have a togglepanel in a datatable, which is working in Ajax mode.

Togglepanel has two states, closed, open and it is intially closed...

In the datatable, only the selected row renders the toogle control.

The problem is, when I click the togglecontrol and change the state of the togglepanel (to open state), it opens and everything is fine, but when the GUI gets an event (we have a4j:push control in the page and datatable is in the reRender defined), toggle control returns to initial state (to closed)...

While I am using the tooglepanel in Ajax mode, I was expecting this not going to happen. I think while the tooglepanel is inside of the datatable that complicates everything and may be what I want is impossible.

Does anybody experienced anything similar and has solution for it...

which version you using?

https://jira.jboss.org/jira/browse/RF-4370

[speleomaniac]

3.3.0.GA

[ilya_shaikovsky]

https://jira.jboss.org/jira/browse/RF-3552

use 3.3.1.

Beta1 is already available

Thx for the tip but 3.3.1-BETA1 didn't solved my problem....

https://jira.jboss.org/jira/browse/RF-3552 is interesting problem but it is not exactly defining the problem I have...

My problem is, if the datatable is once rendered with a togglePanel that is initially closed but switched to open state but user click, when we are getting an event from the a4j:push to rerender the datatable, toggle panel switches to the closed state.

We don't have effect like a chained reaction of several togglepanels...

ok.. lets check your code.

That is the next Problem, my code is extreme complex and lies in several different .xhtml files (included with ui:include)....

I would try to create a test project and send it here...

I was further debuging the problem and I have a question that might have something to do with the problem....

In a4j:push reRender attribute I defined a component that lies in the datatable. The problem I see now in UIComponentBase class, findComponent method there is an if statement defining the following...

if (!(kid instanceof NamingContainer)) {
if (checkId && id.equals(kid.getId())) {
result = kid;
break;
}
result = findComponent(kid, id, true);
if (result != null) {
break;
}
} else if (id.equals(kid.getId())) {
result = kid;
break;
}

The following 'if (!(kid instanceof NamingContainer)) ' prevents that findComponent would go deeper in the component that had implemented the NamingContainer interface....

Is this means that we are not allowed define components in rerender attributes that lies inside of datatable?

[speleomaniac]

Also another interesting piece of code, there is an option to write the reRender attributes in the following form (mainly in NamingContainer.SEPARATOR_CHAR) ':table1:panelToRerender1' so the UIComponentBase can search with findComponent fitting component...

But in AjaxContextImpl class following piece of code exists...

private String convertId(UIComponent component, String id) {
if (id.charAt(0) == NamingContainer.SEPARATOR_CHAR) {
return id;
}
which means UIComponentBase findComponents gets no chance to search the component tree to findout the compoent....

How this sort of reRender attributes are processed?

Ok,

finally I had created the test project, you would initially see that I had problem to use togglePanel in the a4j:repeat. When I click toggle control to expand the element nothing changes in the GUI....

I had created a maven project that you can duplicate the problem, while there is no possiblity to attach this project in to the forums, I will create a JIRA issue so you get the project....

If you can tell me what I am doing wrong I would be gratefull..

There is 2 test pages one containing simple togglePanel to show actually, toggle panel works (http://localhost:8080/toggletest/faces/pages/toggleTest.xhtml)...

Second one same togglepanel is embeded inside of a a4j:repeat control to demonstrate the problem(http://localhost:8080/toggletest/faces/pages/toggleRepeaterTest.xhtml)
