dynamic_package loading metamodels [message #502445]

Hello Community,

I created 3 .ecore files and tried to load them with the extension point dynamic_package of org.eclipse.emf.ecore.
It looks like:

    <extension
         point="org.eclipse.emf.ecore.dynamic_package">
      <resource
            location="models/MDPE-Core-New.ecore"
            uri="http://www.modelplex.org/amf/2008/MDPE/Core-New">
      </resource>
      <resource
            location="models/MDBPE-Company-Core.ecore"
            uri="http://www.modelplex/amf/2008/MDBPE/Company/Core">
      </resource>
      <resource
            location="models/MDBPE-Department-Core.ecore"
            uri="http://www.modelplex/amf/2008/MDBPE/Department/Core">
      </resource>      
   </extension>

After starting a new Runtime-Configuration I find the package registered, when I check it for instance in the Metamodel Explorer. But when I try to load a model, which uses these metamodels, then Eclipse cannot find the used elements of the metamodel.
Also when I try to create in the runtime configuration a new metamodel which should extend one of the registered metamodels, I cannot load one of these through "Load Resource", only possible loading as "Runtime Version" and not as "Development Time Version". By the way what are the difference between these to versions?

Any ideas I would appreciate.
Simon

The should appear in the EPackage.Registry.INSTANCE just like a
registered generated package and should be found just as any other. I'm
not sure why that sound't be the case for you.

Given there is no GenModel for these, there is no development time
version. The development time version is always a dynamic one, but it's
not registered because the generated one is registered instead; it's
wrapped by a GenModel and available in that way.
