> When the ExtendedDataTable contains dynamic columns (i.e. using for:each), "java.lang.IllegalStateException: component with duplicate id" will occur after the second submit from a commandButton.
> The problem does not appear in 4.2.3 Final but found in 4.3 CR1
> Sample source code:
> {code}
> <h:form id="frmMarkUpdate">	
> 	<a4j:outputPanel  id="resultPanel">
> 		<rich:extendedDataTable id="studentVoMarkInputTab"
> 			value="#{updateMarkBean.studentVoMarkAmends}" 
> 			var="studVo"
> 			selectionMode="none"
> 			height="100%">
> 				
> 			<rich:column width="200px" >
> 				<f:facet name="header">
> 					Status
> 				</f:facet>
> 				<h:outputText value="#{studVo.student.markAmendStatus}" />
> 			</rich:column>
> 		
> 			<c:forEach items="#{updateMarkBean.taskVos}" var="tvo" varStatus="s">
> 				<rich:column width="100px">
> 				<f:facet name="header">
> 					<h:outputText value="#{tvo.task.taskName}" />				
> 				</f:facet>
> 				<h:inputText id="task#{s.index}_amk" 
> 					value="#{studVo.getTaskMarkMap().get(tvo.task.taskId).amendedMark}"
> 					size="1" maxlength="3"/>
> 				</rich:column>
> 			</c:forEach>				
> 		</rich:extendedDataTable>
> 		
> 		<a4j:commandButton id="btnSave" value="Save" 
> 			action="#{updateMarkBean.doBeforeSave}" 						
> 			styleClass="button blue">
