Simon van Scheltinga commented on RF-3598:
------------------------------------------

I can confirm this issue with an a4j:repeat tag but with the exception that I experience it only with input fields. If I change for example my h:inputText to an h:outputText the page is rendered correct. But it is only the view that is incorrect, after a full page refresh the correct row is removed. 

<h:form id="repeatForm">
	<a4j:outputPanel id="items">
		<a4j:repeat value="#{demo.items}" var="item">
			<div>
				<h:inputText value="#{item.nr}" required="true"/>&#160;
				<a4j:commandLink action="#{item.doRemove}" reRender="items" immediate="true" >remove</a4j:commandLink>
			</div>
		</a4j:repeat>
	</a4j:outputPanel>
	<h:commandLink action="#{demo.doAdd}" >add</h:commandLink>
</h:form>

> Given the following sample code:
> <t:div id="testDiv">
>     <rich:dataTable
>         value="#{backingBean.holders}"
>         var="holder">
>         <f:facet name="header">
>             <rich:columnGroup>
>                 <rich:column>
>                     <h:outputText value="TestColumn">
>                 </rich:column>
>                 <rich:column>
>                     <h:outputText value="DeleteColumn">
>                 </rich:column>
>             </rich:columnGroup>
>         </f:facet>
>         <rich:column>
>             <h:outputText value="#{holder.testValue}" />
>         </rich:column>
>         <rich:column>
>             <a4j:commandLink action="#{backingBean.deleteRow}"
>                 reRender="testDiv"
>                 value="testLink"
>                 immediate="true">
>                 <f:setPropertyActionListener
>                     value="#{holder}"
>                     target="#{backingBean.toBeDeletedHolder}" />
>             </a4j:commandLink>
>         </rich:column>
>     </rich:dataTable>
> </t:div>
> The Java code in the backingBean to remove the row is:
> public void deleteRow() {
>     holders.remove(toBeDeletedHolder);
> }
> Let's say this table has 4 rows. When you now press the delete link of the second row, the model gets updated correctly, indeed the second row is removed. But in the view, it appears like the 3d row (always the row directly below the row that was intended) is removed, not the second. Removing the immediate="true" attribute resolves the issue, but is undesirable since then validation comes into play, which is precisely why you put immediate="true" on such a component in the first place.
