Yeah, usually something like this would not be a seam-related problem, but we
hacked in some functionality to make JSF method bindings more flexible (and I
screwed up doing it).

BINGO! Built from CVS. I never would have guessed that this was a bug in
Seam. Seems to me that it has more to do with JSF event handling. Anyway,
it's in the rear-view mirror. Thanks for the help Gavin.

Can you try this with a CVS or nightly build of Seam, it looks like a bug that
was already fixed.

I changed the method signature of updateStateRadioChange to no-arg, and it
called it properly. It's looking like I'm completely misunderstanding the way
in which a ValueChangeListener method is invoked.
It's my understanding that when the valueChangeListener attribute is specified
for a comp
Here is the runtime memory (up to the call to
org.apache.myfaces.el.MethodBindingImpl.getMethod()). _argClasses is null,
which tells me that it might be expecting to call a no-arg method, when the
actual method takes a ValueChangeEvent.

Put a breakpoint in the MyFaces code and find out what values it is passing to
getMethod().

NOTE: I abandoned implementation of a ValueChangeListener (earlier posts in
this thread), in favor of invoking the value change listener method on the Seam
component instance itself.

It would help if you showed us the stack trace.

no, that's the first thing I tried, because it's a boolean component. I saw
the same result. When that didn't work, it occurred to me that the type of
component might not even matter, so long as the ValueChangeEvent was created.

Can you make it work for a h:inputText?

Sorry to be so noisy on an ignored topic. I have degraded to a much simpler
question. Has anyone gotten the valueChangeListener attribute to work with
? I have seen a handful of threads around and no one has
ultimately said that they got it to work. The result in my case is a very

I've implemented a ValueChangeListener, to handle the change of the radio
button, but I'm not sure how to change the value in my Seam component, to
reflect the value change. I'm sure I am supposed to be looking up the Seam
component a different way, since it fails with a ClassCastException when
Sorry, hosed the action method (needs to return String), but the main problem
is still the same. Can't force the radio button's value into the Seam
component.
