Description Paul Webster

you can add a "service" 5 ways, each with different implications for when it is available

- when the MPart is created you can just set X.class.getName() => xInstance

- you can set X.class.getName() => context function, that will instantiate and return the xInstance when asked

- you can use the event broker to listen for a context being set, and then perform one of the above 2 steps

- you can provide a context function through DS which will then be available at the root context

- you can simply provide an OSGi service which will be available at the root context

We are adding most of our services 3 ways.  

1) By simply adding them to the context, like in
org.eclipse.e4.ui.internal.workbench.E4Workbench.createWorkbenchContext(IEclipseContext,
IExtensionRegistry, IExceptionHandler, IContributionFactory) (not extensible).  

2) we feed in an OSGi service.

3) we provide a creation function using #1 or #2, which acts like a factory to provide real services when requested.

I'm currently working on lifecycle for commands/contexts/keybinding services in bug 329646.

1) An addon to make the service and support managers available in the context belonging to MApplication

2) An addon to process the model and add event handlers for model changes

3) For the compatibility layer only, a Model processor to push relevant extension point information into the model

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
