[Opensource] Trouble with transitions in JSPs

[Tino Dai]

Hi Everybody,

     I found my problem to the Transition not showing up on the jsp
page. Actually, I found a workaround. I am using either

     In the controller:  response.addTransition(new
Transition("someMethod", this));
			
      			or
			Block newBlock = new Block();
			Transition i = new Transition("someMethod",this);
			newBlock.add(i);
			response.add(newBlock);

	will work.


	But this doesn't work:
	response.add(i) or response.addTransition(i)

Is this a bug or is there a reason behind why we can't do this?
