[jwt-dev] Making new JWT metamodel elements visible in the JWT WE UI

Thanks very much Christian & Florian, this is what I needed ^^

About the extension spec, it is still a work in progress, I wanted to share where I was going to. I'm sure you'll have valuable input on the different alternatives as well !

Hi Marc,

the visibility of the model elements is controlled by the JWT views concept.
If you alter the meta model, the view files (business.view, technical.view
in the views dir) have to be adapted to the new meta model elements.
Unfortunately, this means you'll have to completely recreate both view files
with the jwt-view tool (which can be found on the eclipse cvs), since the
respective version of the meta-model is serialized into these files.
The required steps are:

1. Download and start the jwt-view application. It will load the current
ecore file from the jwt-we project in the same project dir
2. Unmark the checkboxes of the elements/properties which should be
invisible (it may be necessary to resize the part of the application window
to make sure the list of elements is displayed)
3. set the corresponding internal name using the menu ("Business" /
4. save the view to business.view or technical.view
5. repeat the steps for the second view

I hope this will help you in accomplishing your addition to the JWT meta
model. Please don't hesitate to ask if the description was unclear.

Concerning the alterations of the meta model itself:
I'm very sorry, I didn't yet respond to your suggestions. I'll read up on
the proposals and will get back to you asap.

Hi Christian, Florian

I'd like to know
* how to make visible dynamic and static additions to the WEMetaModel.ecore in the Outline and in the property view. I've found the Outline class, I've generated the model and edit and it works well including saving, but nothing is displayed...
   * Chris, how what I say pans out with your ideas about JWT metamodel .

Hi all

I've written about JWT metamodel extension specifications at the bottom of , mainly on * "goals" : summarize all JWT members' goal for such extensions. Obviously everyone's welcome for giving some feedback ! * "design" : summarize my latest tries at hacking the JWT WE metamodel and writing sample extensions. I've still to upload the actual stuff as a bugzilla.

To make it short, for now what I like is an "aspects" relation on ModelElement (or at least Action) to an "Aspect" dynamic interface, and dynamic EMF extensions. I've also tried simple properties.

Feedback welcome !
