Anybody had issues with a:support being flaky, specifically not calling the action/actionListener method when it should? I have the code below and session.hey is never called. FWIW I tried with and w/o the ajaxSingle attribute. Everything is rendered as expected w/proper values in the pull-down list, etc., and the "value" (workerName) is correctly set. I've also tried onblur as the event. Weird thing is I have another screen with virtually identical code except on a <h:inputText> field--and the action method is called. Hmm... Thanks, Greg | <h:selectOneMenu id="worker" | value="#{timecardHome.instance.workerName}"> | <f:selectItems value="#{app.activeWorkers}" /> | <a4j:support event="onchange" | action="#{session.hey}" | reRender="rate" | ajaxSingle="true"/> | </h:selectOneMenu> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4034765#...
