here it is a sample of how PlayActionEvent method could be used:

ASErr
AIArtHandleModifier::Rasterize()
{
          AIErr result = kNoErr;
          AIActionParamValueRef valueParameterBlock = NULL;
          ActionDialogStatus dialogStatus = kDialogOff;
try
          {
                    result = sAIActionManager->AINewActionParamValue(&valueParameterBlock);
                    aisdk::check_ai_error(result);
                    if (valueParameterBlock)
                    {
                              //set valueParameterBlock values (params) before calling
                              //PlayActionEvent method.
                              //It's up to you to set it
                              result = sAIActionManager->PlayActionEvent("ai_plugin_rasterize", dialogStatus, valueParameterBlock);
                              aisdk::check_ai_error(result);
                              result = sAIActionManager->AIDeleteActionParamValue(valueParameterBlock);
                              aisdk::check_ai_error(result);
                    }
               }
          catch(ai::Error& ex)
          {
           //Do something with this!!!
          }
return result;
}

I would like to do something similar, to play back a top-level action as recorded by the user, e.g., the Default Actions' "Rasterize (Selection)" which contains "ai_plugin_rasterize" and could be modified to contain other action items from other plugins as well. Another example is the "Delete Unused Panel Items" user action which contains multiple individual plugin actions. I will know in advance the name of the action I want to play, and wish to exit gracefully if an action by that name does not exist.

My dilemna is that user actions can play user scripts, user scripts can play user actions, but I want to play one or the other directly from my plugin. I suspect this simply is not possible, but must ask before giving up. -- Thanks
