rendered Attribute breaks a4j support?

[gressho]

Hello,

I've tried some time to get an <a4j:support> element to work and
found some strange behaviour:
When I use a4j elements in an element with a rendered attribute it won't work
anymore! In the code below, the a4j:support doesn't do anything, even the
<h:commandLink> doesn't do anything!
When I remove the rendered attribute from the surrounding <rich:panel> everything
works well...
I'm not using RichFaces for long, so I might have made some errors and would be
grateful to anybody showing me a way through this.

I forgot to mention: I'm using JBoss 4.2.2, JBoss Portal 2.6.4, JBoss Portlet Bridge 1.0.B1 and RichFaces 3.1.4.

Don't know about the render tag, but I think you have few mistakes in your page.
1. Why do you use a4j:form? a4j:form is for special cases and doesn't work as you expect with h:commandButton.

2. You declare your a4j support as immediate="true", in this case the model is not updated so you will so no change in #{mandatorManagement.mandator.description}" value, use immediate when you need to validate or do some action, but not if you want updateModel phase to be activated
