EContentAdapter on BPMN EMF model [message #652682] Sat, 05 February 2011 08:34 Go to next message

Hi,

I am trying to integrate with the BPMN modeler. My domain model is also an EMF model.

I wanted to listen to changes in the BPMN EMF model and correspondingly make changes to my domain model.
I created my EContentAdapter to listen to these changes:

editor.getDiagram.getElement().eAdapters().add(myListener)

However whenever the name of an Activity (Task) is modified I dont get any notifications. I only get notifications on Add and Remove.

I am not sure why this is happening. What exactly am I missing?

Also I want to listen to changes on even those BPMN models (editor) that are already opened (from my previous run).
What would be the best way to achieve this.

Any help would be really appreciated.

Thanks a lot,
Nidhi

P.S: I was not sure whether to post this on the BPMN newsgrp or EMF newsgrp. Please do let me know in case this is not the right place.

How does your EContentAdapter look like? Most errors i've seen is that
people are not not calling super when overloading the notify-method.

Hi Tom,

Awesome!!! this works.
I am just curious to know how did this worked!

For Add and Remove it works just fine, but for modifications it does not. Is it to do something with Add and Remove notifications coming from the parent. I need to dig deeper.

Thanks a lot Smile,
Nidhi

Hi Tom,

Would you also have the answer to my second question:

Also I want to listen to changes on even those BPMN models (editor) that are already opened (from my previous run). What would be the best way to achieve this.

Thanks again,
Nidhi

Nidhi,

If you don't call super, the adapter won't get attached to any child
objects.

Nidhi,

You're asking how to access all the open PBMN editors to listen to
notifications from the models. There's an IPartListener that lets you
listen to things happening in the IWorkbench, but that's a general
Eclipse question best asked in the JFace or Platform newsgroup. Maybe
the editors themselves implement IEditingDomainProvider; it's best to
ask on the BPMN newsgroup about that.

Hi Ed,

Thanks for both the replies. As you advised I posted the second question to the BPMN group.
Though IPartListener is probably what I was looking for.

Best Regards,
Nidhi
