Eclipse Plugin Development - Modify the outline of JavaScript editor

Question

I'm writing an eclipse plugin for JOII but got stuck on modifying the outline in a JavaScript editor.

I have a ContentAssistant that provides me with a list of ICompletionProposal and got the IJavaCompletionProposalComputer functioning perfectly, giving me nice code completions as I type. There is, however, no outline for it (besides the default javascript stuff).

So the question is: How do I hook the ContentAssistant into something that alters/updates the outline view?

Example code I'm parsing with the plugin:

var SomeClass = Class({
    foo: function() {},
    bar: function() {}
});

In the outline, "SomeClass" is shown as: SomeClass : Any, but I'd like it to display itself as an actual class with the members.

I've been searching all day (litterally) for an example on this, but no luck..

Thanks in advance!!
