What about creating a method:
public void doThisAndThat()
And invoke just doThisAndThat with one a4j:support
So you don't have to touch the doThis, and the AndDoThat methods, so they can be used by other events.
yes thats clear:-)
It seems, it is not possible to do it with a4j-tags alone, providing a list of method which should be invoked or nested a4j:supports..
its possible to use nested f:selectActionListener tags. It could be more than one tag inside support defined.
