Hi!
your PageLifeCycle listner is registered twice,
so he is executed twice :)
My guess is that your custom faces-config.xml is parsed twice.
Do you refer to "faces-config.xml" in your web.xml file ?
If so it is parsed twice.

You're right.... I am getting six listeners...
"listeners"= PhaseListener[6] (id=89)
[0]= ExtensionsPhaseListener (id=2387)
[1]= AutoScrollPhaseListener (id=2384)
[2]= PageLifeCycle (id=2385)
[3]= ExtensionsPhaseListener (id=2386)
[4]= AutoScrollPhaseListener (id=2388)
[5]= PageLifeCycle (id=88)
PageLifeCycle is my custom listener.
I did what you suggested and found that Myfaces and JSF is starting the
listeners..
here is my log:

I think my problem my be that I have jsf and myfaces jars in my lib.
I have both because we have a custom component for a datatable and they need
both jars.
I may need to rewrite custom component to use only MyFaces.
This will be hard since there are objects in JSF and not in MyFaces.
I need to find code in MyFaces for the datatable. Is there any where I can
look to see how to create a custom component thats renders a table in
MyFaces?
Thanks for all your help.
