E4 application model editor - doesn't open model with imported packages [message #939425]

I create custom model elements and use it in app model - editor doesn't open model with this elements. It can not find package referenced from app model file by xmlns. The project containing model (ecore, genmodel and generated code) is in dependencies of project with app model. This project contains the extension point describing package uri. All work correctly (the model successfully extended), but app model editor has problem to open model file. Is it bug of editor or editing extended model is not implemented now?

Such exception is appear:

org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: org.eclipse.emf.ecore.xmi.PackageNotFoundException: Package with uri 'http://www.semanticsoft.org/ExtensionUI/e4modelextension' not found. (platform:/resource/org.semanticsoft.e4test/Application.e4xmi, 2, 620)

I don't think this is a problem of the e4-editor but rather how you
included your ecore which must point to a workspace location.

Beside that please note that the model editor has an extension point to
add forms for your custom types.

Ecore adressed correctly by genmodel and genmodel itself also adressed correctly by extension point:

<extension point="org.eclipse.emf.ecore.generated_package">
      <package
            uri="[url]http://www.semanticsoft.org/ExtensionUI/e4modelextension[/url]"
            class="e4modelextension.E4modelextensionPackage"
            genModel="model/e4modelextension.genmodel"/>
   </extension>

Model extended correctly becouse application work correctly. The problem only with model editor.

Is there are example showing this?

The important thing is how your .e4xmi references your extension .ecore
file!

Tom, are you remember discussion in theme "Eclipse 4 and Web"? You adviced me to patch event broker for isolating events in single workbench. Today I have decided to try your patch - I have create custom event broker class end register it with ContextFuction. All work ok! Now events really isolated and vaaclipse is almost ready to real use.

But first I must to solve the current problem. I can not understand this:

And the example how to provide forms for custom model elements will be very helpfull...

Can you send the .e4xmi you want to use in the model editor? The problem
is that your extended .ecore is not known to the editor unless you run
in an inner workbench.

There is the SimpleIDE stuff which shows how to register a form editor
for custom elements.
