Re: Why afterPhase(PhaseEvent event) gets called twice
Hi,
I am having the same problem. My phaselistener is being called twice, I
do not have configs entry in my web.xml, so it's not that.
Just wondering.... Did you ever find out why yours was being called twice.
thanks.

Hi,
is the "com.sun.faces.util.Util" part of their -impl JAR file?
If so it is general bad to code against impl stuff.
Since the RI is open source, just go ahead and *copy* the code over to
your custom java code. Not a big deal. You can code against that *new*
util clazz
(not sure how many dependencies that guy has to other sun ri internal clazzes)

Re: Why afterPhase(PhaseEvent event) gets called twice

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.

Re: Why afterPhase(PhaseEvent event) gets called twice
Posted by "A.McCall" <am...@rosettatg.com>.
Simon,
Can you point me to where I can find source code for MyFaces?
I am really having a hard time trying to re-create my custom component in
MyFaces.
My first problem is that I can't find the compatible library for
com.sun.faces.util.Util in MyFaces.
Thanks.

Re: Why afterPhase(PhaseEvent event) gets called twice
Posted by Simon Kitching <si...@rhe.co.nz>.
Yep, having both the Sun and Myfaces implementations in the classpath is
likely to cause all sorts of problems. The Sun "ConfigureListener" is
there in the stack trace; I would guess that it is searching for all
META-INF/faces-config.xml files and processing them, and so is MyFaces,
thus adding every phase listener twice.
There are no objects "in JSF" that are not in MyFaces; the MyFaces
"core" library is a 100% feature-complete implementation of the JSF 1.1
specification.
If you want to see how to write a custom table implementation, you could
look at the source for the MyFaces Tomahawk library; it includes a
custom table. Before doing this, though, are you quite sure you do need
to write a custom table? The tomahawk table is pretty flexible...

Re: Why afterPhase(PhaseEvent event) gets called twice
Posted by "A.McCall" <am...@rosettatg.com>.
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..

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.

What I was expecting is that you would see two copies of *your* phase
listener in that list. At the very least, you should see *one*,
otherwise you wouldn't be getting any callbacks at all!
The phase listeners you list below are normal, and won't be making
callbacks to your code.
Just FYI, JSF implementations are required to look for all occurrences
of META-INF/faces-config.xml in the classpath and process them all on
startup. A faces-config file can provide a list of phase-listeners to be
regisered on startup; if you look inside the tomahawk jarfile you will
find a faces-config.xml file that defines these two listeners. To
repeat, though, these are nothing to do with your problem.

Simon

Simon,
I did what you said. You are absolutely right...I do have 2
listeners...
1. org.apache.myfaces.renderkit.html.util.ExtensionsPhaseListener
2. org.apache.myfaces.renderkit.html.util.AutoScrollPhaseListener
I do not see where these listeners are configured.
Do you know how I set it up so I just have one listener?
Thanks.

Phase listeners work fine for me. I'd be willing to bet that you do have
the phase listener registered twice.
I suggest that in your phase listener you get the list of registered
listeners then iterate through this and check that there is only one
object whose class is your custom listener class.
LifecycleFactory factory = (LifecycleFactory)
FactoryFinder.getFactory(FactoryFinder.LIFECYCLE_FACTORY);
Lifecycle lc = factory.getLifecycle(LifecycleFactory.DEFAULT_LIFECYCLE);
PhaseListener[] listeners = lc.getPhaseListeners();
If it is registered twice, then you could put a logging statement in
your phase-listener's constructor that prints out the current stack
trace; that will show you where the instances are being created.
Regards,
Simon
