 Can a Fragment extend a Fragment? [message #1009861] |

So my main plugin defines the application model, with relatively little in it. Main it creates a PerspectiveStack with an ID. (Application.e4xmi, below)
Another plugin defines a fragment which extends the application model by adding a Perspective to the PerspectiveStack. (tools_fragment.e4xmi, below) It does this by giving the Element ID of the Perspective Stack and a Featurename of children. Under elements I add a Perspective. That Perspective defines different things, one of which is a PartStack with a specific ID.
So far, so good. The app comes up fine and I see my perspective.
Then I have a 3rd plugin that defines another fragment. (support_fragment.e4xmi, below) This defines a fragment with an Element Id that is what was used for the PartStack in the second plugin, a Feature Name of children, and several Elements that are parts. When I run the app, none of these parts appear.
What a I doing wrong? Is it not possible to extend a fragment with another fragment? Do I have to do something so that some sort of load order is set?

Well the problem most likely is that the bundles are processed in the
wrong order (which by default is random!) by the extension registry:
* Main-Bundle
* Parts-Bundle
* Perspective-Bundle
where as you'd require:
* Main-Bundle
* Perspective-Bundle
* Parts-Bundle
You can remove this randomness by adding dependency from your
Parts-Bundle to your Perspective-Bundle because we guarantee this order
when processing the contributions.
