dataTable does not re-render correctly after deleting a row with immediate="true"
---------------------------------------------------------------------------------

                 Key: RF-3598
                 URL: http://jira.jboss.com/jira/browse/RF-3598
             Project: RichFaces
          Issue Type: Bug
    Affects Versions: 3.1.4
         Environment: JBoss 4.0.5, JSF 1.2
            Reporter: Jonck van der Kogel
            Priority: Critical


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.
