Instantiating a plugin's action

hi,

i would like from my plugin get hold of an action of another plugin that i depend on (scala). my naive approach was this:

   val am = ActionManager.getInstance
   val actionRunConsole = am.getAction( "org.jetbrains.plugins.scala.console.RunConsoleAction" )

but this doesn't get me the action. i guess it needs to be "loaded" somehow. how would i load this action?

and then, how do i invoke it. here is my guess:

         val callBack = am.tryToExecute( actionRunConsole, origin.getInputEvent, null, origin.getPlace, true )
         callBack.doWhenDone {
            inform( "console opened" )
            doSomethingElse
         }
         callBack.doWhenProcessed { inform( "console processed" )} // what does that mean, actually?
         callBack.doWhenRejected { inform( "console rejected" )}


correct?
