I have a couple modules that use partial rendering and intercomunicate to each other with IMC, the problem is that altought the event gets passed the receiver module doesn't displays the changes.

Any help would be appreciated.

OK - I've finally sorted this out - thanks to Onishiro's post that put me on the track.

The fault of no rendering in the IListener module, even though the IMC Event is actioned,  stems from the fact that the ICommunicator module invoking the Event has Partial Rendering ON, thereby precluding any rendering on the IListener page. Unticking the IModuleCommunicator Module's Partial Rendering option box allows the IModuleListener page to render normally.

The IModuleListener module can, of course, have Partial Rendering on or not as you wish.
