------------------------------------

Hi, You welcome! The workaround is (the context menu`s items #cmi1 and #cmi2 will be re-rendered on row selection change, 
then, after #cmi2 action, the table and contextMenu will be re-rendered):

<rich:extendedDataTable id="table" selection=#{listener.selection}>
  <a4j:ajax execute="@form" event="selectionchange" listener="#{listener.selectionChanged}" render=":cmi1 :cmi2" limitRender="true"/>
  <rich:column>Column Content</rich:column>
</rich:extendedDataTable>

<rich:contextMenu id="contextMenu" mode="ajax" target="table" showEvent="click">
            <rich:menuItem id="cmi0" label="I am invisible" mode="client" style="display: none;"/>
            <rich:menuItem id="cmi1" label="I am visible" mode="client"/>
            <rich:menuItem id="cmi2" label="I am visible too" mode="ajax" render="table contextMenu" limitRender="true"/>    
</rich:contextMenu>

The sequence of execution is:
1. click event sent to the table
2. contextMenu is shown, since it reacts on click event
3. the onchange event is processed and AJAX request sent to the server
4. the partial update response with new #cmi1 and #cmi2 item contents is processed on the client and 
5. the DOM of #cmi1 and #cmi2 is replaced in the contextMenu popup already shown

And by the way every time the table is rendered, the contextMenu MUST be re-rendered as well, otherwise the "showEvent" becomes unregistered...
