ServiceDesk

So I am led to believe dialogue components can have message listeners enabled on them which means you can send messages to the component to get it to do something, like accept some values and move on.... For example to automatically close a ticket (which I have used).

I am wondering though just how these work and whether many of the other dialogues (especially in ServiceDesk) accept messages. If they do what messages do they accept and how do we configure them? Can I for example get the change management process to automatically go through the plan acceptance dialogue stage by providing a message with the right information for it to move it forward?

 If so where is this and all the possible messages for ServiceDesk documented, as I don't seem to be able to find much on this...

Thanks in advance

I think I've answered this myself. Looking at the Change and Incident Management core workflows only the work incident dialogue has message listeners configured and therefore can be exited through message automation. This seems a shame as it does limit the ability to change and automate these 'locked down' workflows. 

I'm not entirely sure how the messaging works though. Maybe someone could point me in the right direction?
