I have a loop in my JSF page generated with ui:repeat. Inside that loop I have a h:selectOneMenu with a a4j:support side it. I also have a a4j:outputPanel inside the loop. My question is how I can make my selectOneMenu trigger a reRender of the correct a4j:outputPanel. I tried setting the id and reRender attributes of the a4j:outputPanel and a4j:support to the id of the entities I iterate over, but that doesn't work. The code looks something like this: <ui:repeat var="dayTime" value="#{planWorkBean.dayTimes}"> | <h:selectOneMenu value="#{dayTime.workShift}"> | <s:selectItems value="#{workShifts}" var="workShift" label="#{workShift.name}" noSelectionLabel="-" /> | <s:convertEntity /> | <a4j:support action="#{dayTime.setWorkShift(workShift)}" event="onchange" reRender="#{dayTime.id}" /> | <h:selectOneMenu> | | <a4j:outputPanel id="#{dayTime.id}"> | <h:outputText value="#{dayTime.workShift.totalTime}" converter="HourMinuteConverter" /> | </a4j:outputPanel> | </ui:repeat> Everything but the reRendering works great. The entity is updated at the onchange event, but the a4j:outputPanel is not updated. I guess I can't use EL-expressions for the id-attribute in JSF-tags, but how else am I supposed to refer to the correct a4j:outputPanel?
