Method binding calls not being made
I am trying to create an admin section for an online database, right
now I'm simply trying to create basic add/edit/remove functionality.
Almost everything seems to work, except that my bound methods only
call sometimes. There is not logical reason I am seeing for this,
there is nothing in my logs about it. When I have my SelectOneListBox
bound to a property it pretty much ignores it, once in a while it
will try to call the getter, but it has never called the setter.
I have tried every combination of things to try and get it working
but most seem to have no effect. Does anyone else know if maybe it's
the Apple JDK or the Spring Framework's DelegatingVariableResolver,
the Tomahawk extensions, maybe even the fact that I have multiple
commandXX's in the form?

Re: Method binding calls not being made
Posted by Mike Kienenberger <mk...@gmail.com>.
Possibly validation is failing and the lifecycle never reaches the
point where it would execute your action.
You might try sticking in
<h:messages globalOnly="true"/>
<h:messages globalOnly="false"/>
and see if anything shows up.
Otherwise set a breakpoint in LifecycleImpl.execute() and see what
phases are being executed.
