<h:selectOneMenu display prevoius value, how to reinit it again?
When click on <a4j:commandLink>, it will call resetCurrentValue method and doing reinit the field values. Once completed, a popup will be shown. However the drop-down list in that popup panel still display previous value.
If I include render=":popupPanel:form2:firstList" in <a4j:commandLink>, drop-down list is reinit however, it will trigger event change listener when click the drop-down value second time....
