seems that the binding of myListener (myListener="#{fravaersoplysningerController.testListener() ) is resolved to null. If i try to remove the " method-signature="void listener()" " i dont get the exception anymore, but ofcourse i lose the desired functionality. </p> <p>If i try to bind the #{fravaersoplysningerController.testListener() method to lets say a button on my xhtml site the method gets called with no problems.</p> <p>Any ideas whats wrong?</p> <p>I am running on : JSF 2.1.26, JBOSS 5.1, Primefaces 4.0.4, EL 2.0.2</p>
