--------------------------------------
Lukáš,
I've been experimenting some more and am thrilled to report MyFaces 2.0.5 (released a
couple weeks ago, sorry I hadn't noticed) appears to fix this issue! So I guess it is
a bug in MyFaces 2.0.4 (and possibly before). Maybe you could note that somewhere in the
documentation?
However this had led to a related issue: dynamically created TabPanels can fail on
POSTback. I attach a small sample app that demonstrates the problem. Deploy the app into
Tomcat 6, then:
1. Go to http://localhost:8080/addressbook-myfaces2-richfaces/index.jsf
2. Click 'Mr Charles Montgomery Burns'
3. Click the 'Other' tab
4. Click 'Edit'
You will get:
Caused by: java.lang.NullPointerException
at org.richfaces.component.AbstractTabPanel.getActiveItem(AbstractTabPanel.java:64)
at org.richfaces.component.AbstractTogglePanel.encodeBegin(AbstractTogglePanel.java:168)
at org.metawidget.faces.FacesUtils.render(FacesUtils.java:94)
at
org.metawidget.faces.renderkit.html.HtmlLayoutRenderer.layoutChild(HtmlLayoutRenderer.java:161)
I believe this is because the 'Other' tab is created (and recreated) dynamically
in code, and so is not available to AbstractTabPanel.getActiveItem. I would be happy if
AbstractTabPanel.getActiveItem just reverted back to the first tab in this case (which is
what RichFaces 3.x did)
Regards,
Richard.

Key: RF-10951
URL: https://issues.jboss.org/browse/RF-10951
Project: RichFaces
Issue Type: Bug
Security Level: Public(Everyone can see)
Affects Versions: 4.0.0.Final
Reporter: Richard Kennard
Assignee: Lukáš Fryč
Fix For: 4.1.0.Milestone1
Attachments: RichFacesDynamicComponentTest.zip
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).
