extendedDataTable re-rendering 
-------------------------------

                 Key: RF-11447
                 URL: https://issues.jboss.org/browse/RF-11447
             Project: RichFaces
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 4.0.0.Final
         Environment: Mojarra 2.1.3.
            Reporter: Brendan Healey



I've got a h:selectOneMenu inside a column of an extendedDataTable which can
be used to modify a property of the current row. The changeInviteState
valueChangeListener persists the modification to the database. What I would
expect to happen in the below example is that the getEventTeamList() method
returns the current data, selectOneMenu is used to make a change and the
nested "<a4j:ajax render="teamTable"/>" causes the table to be re-rendered
(the table getter getEventTeamList should be called to refresh the data).

The problem is that this re-rendering of the table doesn't happen. I see the
value change listener firing but the table value getter is not executed after
the VCL.

The importance of being able to re-render the table after the data change is
that when using optimistic locking the table will contain a stale version
number and subsequent modification attempts will fail (unless you refresh the
data before making a modification, but that is an inferior approach).

Note that removing <a4j:ajax event="selectionchange" makes no difference.

<rich:extendedDataTable
        id="teamTable"
        binding="#{bean.teamTable}"
        value="#{bean.eventTeamList}" var="var"
        selectionMode="single"
        selection="#{bean.selectedTeamRow}">
        <a4j:ajax event="selectionchange"
                  listener="#{bean.teamRowSelect}"/>
        <rich:column style="text-align: center">
            <h:selectOneMenu value="#{var.inviteState}"
                             immediate="true"
                             valueChangeListener="#{bean.changeInviteState}"
                             rendered="#{bean.showStatusInput}">
                        <f:selectItems value="#{bean.teamStatusOptions}"
                                       var="svar" itemLabel="#{svar.localName}" itemValue="#{svar}"/>
                        <a4j:ajax render="teamTable"/>
                    </h:selectOneMenu>
        </rich:column>
</rich:extendedDataTable>
