I am afraid you hit a problem of JSF 2.0. It's currently not possible
to retarget a special method expression (like valueChangeListener)
from one composite component to another (and, of course, also not to
its children).
See JSF spec issue:
http://java.net/jira/browse/JAVASERVERFACES_SPEC_PUBLIC-755

Hi,
the standard component is a UINamingContainer. Could you please send
me the whole markup of the composite component?

Jakob

Thanks for the code. But I still don't get it working.
I didn't specify a componentType for my implementation, so it should be a
standard implementation which does inherit the right finComponent() api.
Also my nested composition is a standard implementation. But I do know now
that the problem is with my nested compositions, that the
ValueChangeListener is not passed to this nested composition. How do I do
that?

Betreff: Re: ValueChangeListener + composite components
Here is the code from
FaceletViewDeclarationLanguage.retargetMethodExpressions:
UIComponent innerComponent = topLevelComponent.findComponent(target);
if (innerComponent == null)
{
if (log.isLoggable(Level.SEVERE))
log.severe(Inner component + target + not found when
retargetMethodExpressions);
continue;
}
...with topLevelComponent beeing the composite component. Thus, in
your example, your composite component needs to be able to find the
target component via findComponent().
Please refer to the javadoc of findComponent() and check if it is
implement correctly on all the components inside your composite
component. My guess is that the parent component of the f:facet does
not check his facets in findComponent().

Jakob

Hi Matthias,
Try using the relative clientid
ValueChangeListener + composite components
Hello guys, I have a problem with the valueChangeListener on my composite component. I = have following structure: composite:interface name=3Dcheckbox ... composite:attribute name=3DvalueChangeListener targets=3DinputComponent= / ... /composite:interface composite:implementation template:c1 ... f:facet name=3DinputFacet h:inputText id=3DinputComponent / /f:facet ... /template:c1 My error message is: FaceletViewDe E Inner component valueChangeListener not found when retarge= tMethodExpressions When I tried to give the composite:attribute name=3DvalueChangeListener targets=3DinputComponent= / on my c1-Interface the Error-Message didn't appear, but the ValueChang= eListener still wasn't called. Second thing I tried was to give the h:inputText id=3DinputComponent / not in the facet-Definition, but only= in my implementation and then the ValueChangeListener worked. What is my mistake, or does composition not work properly with facets? LG
