Anyone any idea why there isn't the attribute "rendered" any more? It existed in the old a4j:support in Richfaces 3.
In Richfaces 4 it disappeared, probably because the underlying f:ajax doesn't have the attribute either...
The thing is that I can't wrap a a4j:ajax in a ui:fragment (Faces exception thrown..)
So how do I add ajax behavior conditionally at runtime??
Ok,
I found out this one by myself:
I can use the "disabled" attribute to switch off the ajax call.
