rich:componentControl (RichFaces 3 to 4 migration)

Question

In our web project we were using rich:contextMenu and rich:componentControl. After migrating to jsf2 (richFaces 4) all the pages with those components starting throwing npe even after following rules for migration (for contextMenu, richItem and componentControl).

Code for contextMenu is:

<rich:contextMenu attached="false" id="contextMenu" hideDelay="400" disableDefaultMenu="false">
      <rich:menuItem action="#{bean.action}" icon="/images/icon.png" label="label">
        <a4j:param assignTo="#{bean.id}" value="{id}" />
      </rich:menuItem>
    </rich:contextMenu>

componentControl is located inside of a rich:dataTable for whose rows I want contextMenu to be shown. Code for componentControl is:

<rich:componentControl event="onRowClick" target="contextMenu" operation="show">
  <f:param value="#{row.id}" name="id" />
</rich:componentControl>

Stack trace is as follows:

Is there anything else that needs to be changed in order for this to work?

Components in RF 4 that handle events accept lowercase names without on, in your case:

<rich:componentControl event="rowclick" target="contextMenu" operation="show">
