Ok, here is a reply to all:
What happens if you use an h:commandButton instead? - Doesn't matter
What happens if you dump the render statement? - Then the update
method is called just fine
Is "#{not categoryAdmin.updateMode}" legal? I've always used ! to
this point - yes, this is legal.
is your method signature correct? - Yes, I am importing the correct class
try to use an action instead of an action listener - is
this called? - I get the same results with this. The update method is
not called.
Thanks for all the suggestions guys.
