Hi, perhaps a cap in my mind. I try to call an action, but the method is never called here the jsf code fragement <div class="entry"> | <a4j:log hotkey="M" /> | <a4j:commandButton value="Reload" action="#{measureEdit.onListLoad}" reRender="Sensor"/> | <div class="label">Sensor:</div> | <div class="input"> | <a4j:region renderRegionOnly="false"> | <h:selectOneMenu id="Sensor" value="#{messkette.sensor}" | converter="#{selectItemHelfer}" required="true" disabled="#{gesperrt}"> | <f:selectItems value="#{measureEdit.alleSensorenMitBlank}" /> | <a4j:support event="onchange" reRender="Funktion, Sensormessbereich, Einheit, Sensorwarnung" /> | </h:selectOneMenu> | </a4j:region> | <h:message for="Sensor" styleClass="message" /> | <div><h:outputText id="Sensorwarnung" value="#{measureEdit.sensorWarnung}" styleClass="kursiv" /></div> | </div> | </div> When I press the button the onListLoad() method from class MeasureEdit should be called, but nothing is done. <a4j:commandButton value="Reload" action="#{measureEdit.onListLoad}" reRender="Sensor"/> The pojos MeasureEditBean.java @Stateful | @Scope(ScopeType.CONVERSATION) | @Name("measureEdit") | public class MeasureEditBean extends AbstractUnderEditorBean< MeasuringChain, Testbed> implements MeasureEdit{ | .... | public String onListLoad() { | // TODO Auto-generated method stub | System.out.println("invoked"); | selectItemHelfer.onListLoad(); | return null; | } | } MeasureEdit.java @Local | public interface MeasureEdit extends AbstractEditor<MeasuringChain> { | | ... | | public String onListLoad(); | } What's wrong in my mind?
