This one is really confusing me or maybe I am missing something. However, the a4j support tag does not allow the value evaluation on any input field (inputText, inputCalender etc) unless the field is disabled. Here's what I mean:
<s:decorate template="layout/edit.xhtml"> <ui:define name="label">Timeline</ui:define> <h:selectOneMenu id="timeline" value="#{selectedTimeline}" required="false" immediate="true" valueChangeListener="#{task.timelineSelected}"> <s:selectItems id="timelinelst" value="#{timelineList}" var="timeline" label="#{timeline.description}" noSelectionLabel="Select..." hideNoSelectionLabel="false" /> <s:convertEntity /> <a:support event="onchange" reRender="timelinedates" ajaxSingle="true"/> </h:selectOneMenu> </s:decorate> <a:outputPanel id="timelinedates"> <s:decorate template="layout/edit.xhtml"> <ui:define name="label">Start Timeline</ui:define> <t:inputCalendar id="startdatecal" renderAsPopup="true" renderPopupButtonAsImage="true" popupDateFormat="MM.dd.yyyy" value="#{selectedTimeline.startDate}" required="true"> <f:convertDateTime pattern="MM/dd/yyyy" /> </t:inputCalendar> </s:decorate> </s:decorate> </a:outputPanel>
