Add functionality to the GPD

[sidkennedy]

Hello to all,
I decided to open a new thread because I think my issue is a little bit another direction than the one where I made a post. So I'll explain my problem:

I want to add some functionality to the Graphical Process Designer (GPD) Plugin. I don't want to rewrite that plugin because I
want that my plugin can be used with future versions of the GPD. The GPD
has an Outline View and I want to add some nodes there. Is it possible
to hook into an existing view and add some own nodes?

In an Eclipse-newsgroup I got this answer:

It all depend on how the GPD plug-in was created (which, I suspect,
nobody on this list is familiar with).

Do you know what kind of object is being displayed the list? You may be
able to provide an objectContribution for it.

This question might get more (and better) answers on a JBoss jBPM forum.

And that's why I'm here. So can anybody help me?

So what you basically ask is a plugin for a plugin... hmm... The most simple way to create custom nodes like is done for the ESB node (look in the source how it is done), but I'm afraid (yet no expert) that you do have to 'change' the basic GPD.

well I'd like not to change the GPD plugin. For what stands the ESB-node? In the documentation(http://docs.jboss.com/jbpm/v3.2/userguide/html/processmodelling.html#nodes) I can't find anything about that node :(

As I have replied in the other thread, it is best to checkout the code of the designer, look at the provided extension points and see how they are used by the designer itself.
