Ecore Model Editor help [message #1802626]

I am having two problems that probably have easy solutions.

1. I have right clicked the Sample Ecore Model Editor and selected "Load Resource..." I've loaded several resources while trying to solve problem #2. How do I unload these resources? I have searched the source for the .ecore file and the .genmodel file and can't find any mention of the resources I've loaded. However, when I close and reopen the ecore file, there they are. How do I remove resources I don't need?

2. I want one of my generated EClasses to inherit from org.eclipse.emf.common.notify.Adapter so that I can add it to another EObject's eAdapters collection. What resource do I need to load to put Adapter in the scope necessary to add it to the list of my EClass' ESuper Types.

Thanks for the help!

Hi

1. Referenced resources will perist, so you need to remove your experimental references. Sometimes I find it easier to edit the XMI with a text editor and delete XML elements there.

2. There is no Resource with an Adapter, since it is a Java class. You can reference any Java class by defining an EClass and specifying its instanceClassName. Or you manually annotate the generated Java with an @extends. Adding an EObject as an eAdapter seems like a really bad idea. I suggest a rethink, perhaps using a regular reference.

But, how do I do that? For example, I loaded platform:/resource/org.eclipse.emf.ecore/model/Ecore.ecore. When I search the XMI contained in my ecore model, I cannot find anything containing "emf.ecore." There must be some other place that Eclipse stores which resources have been loaded into the .ecore model.
