take a look at rendered="#{categoryAdmin.updateMode}" which must be true
to process the actionlistener when the request is decoded. Save the
state of categoryAdmin with t:savestate or make the bean session scope.
Hope that helps.

FYI - the missing # from the actionListener in
<x:commandButton id="updateButton"
actionListener="{categoryAdmin.update}" value="Update"
rendered="#{categoryAdmin.updateMode}"/>
was corrected as I was typing in a hurry. The problem still persists.
Thanks for any help. And I am using MyFaces 1.0.9. Using the latest
nightly snapshot did not resolve this issue either.

I'm not sure if this is an issue with MyFaces or with how I am doing
what I am doing or what. I have a very simple page with a a
dataTable. I am wanting to edit the data in the dataTable inline.
That is to say, not navigating to a seperate page. I have it setup
with an edit button for each item and when that button is pressed I
render inputText components and an update button for the associated
row. This works.
The problem is that the update button's actionListener method binding
isn't working. When I press the update button, nothing happens. The
update(ActionEvent event) method is never called. It doesn't matter
if the bean is in the session or request. It just doesn't call the
method. I have stripped the code down to the simplest working example
that demonstrates this problem which I will post below. As it is
right now, I am merely showing and hiding the update/edit buttons.
When I press Edit the edit method is being called and the update
button is rendered where the edit button is now not rendered. If I
hit update button, the update method is never called and the edit
button is displayed again, hiding the update button. I realize that
with each button press a new request is being sent to the server.
However, it JSF is supposed to save the state of the bean for
actionListeners since it does not navigate from the page. However, I
don't believe this is working correctly. Any ideas? Thanks.
