Lukáš Fryč commented on RF-10951:
---------------------------------
Hi Richard, I have debugged your sample and got final conclusion, there are
actually two things wrong.
You are generating panels for "viewing" mode and they got j_id23 and j_id25 ids
implicitly. But when you are switching to "editation" mode, you are creating
new tab which will got j_id54. The current tab is described by tab name, which
defaults to tab id. So when tabPanel tries to discover second tab with
name=j_id25 it doesn't find and fails with NPE on check item.isDisabled().
You should rather:
1. reuse the second tab and populate it with new components
2. use explicit names which will not dependent on ids
But it changes nothing on fact that I will rewrite the condition on disabled
more defensively.

> Hi guys,
> First, thanks for a great release in RichFaces 4!
> I have come across (what I think is) a bug and have put together a small test
> app that reproduces it. RichFaces components that are creating dynamically
> (programmatically) using...
> application.createComponent( context, componentType, rendererType )
> ...do not automatically re-inject their CSS/JavaScript resources into
> <h:head/> following a POSTback. For example, if an incorrect value is entered
> into a field and a validation error occurs, no programmatically created
> RichFaces components work when redisplayed. In fact, they may not redisplay
> at all (having lost their CSS).
