Hi all,
I'm trying to create a plugin, in which I have two more or less separate EMF
models.
the first is located in the package nl.company.egen.model, and the second in
the package nl.company.egen.modeldef.
I have two separate ecore files in my model folder, located in the project's
root.
I have created a view, which opens the second (modeldef) model, and displays
it in a treeview. However, sometimes the error
Unable to create view: org.eclipse.emf.ecore.xmi.PackageNotFoundException:
Package with uri 'http:///nl/company/egen/modeldef.ecore' not found.
is thrown on opening the view.
I do have both ecore files (model.ecore and modeldef.ecore) included in the
build / manifest (both in the binary and in the source)
Also all nl.company.modeldef.* (generated) packages are exported.
Here's the contents of the emf modeldef file I'm trying to show in the view.
<?xml version="1.0" encoding="UTF-8"?>
<nl.company.egen.modeldef:DefDefinition xmi:version="2.0"
xmlns:xmi=http://www.omg.org/XMI
xmlns:nl.company.egen.modeldef="http:///nl/company/egen/modeldef.ecore"/>
btw, I'm still using emf 2.2.0 v200605231736. I guess I should update one of
these days, but I'd like to get this working before introducing possible
other uncertainties.
Does somebody knows what is causing this exception ? (And how I can avoid
it?)
TIA
Ronald

One addition; It works when I delete the file and create it again (with the
emf generated new model wizard).
After that, I can open the view.
But on closing my secondary eclipse instance and reopen it again from the
primary eclipse instance,
it fails again. Do I have to register the model somewhere before it
recognises the model ?

Ronald,
Generated models are registered like this in the plugin.xml
<extension point="org.eclipse.emf.ecore.generated_package">
<package
uri = "http://www.example.com/Library"
class = "com.example.library.LibraryPackage"
genModel = "model/Library.genmodel" />
</extension>
and this ensures there is a registration for them in
EPackage.Registry.INSTANCE. Is that missing for your plugins?

Wow, sorry I missed the obvious, but thanks for pointing that out.
I guess I was just buried too deep in all the details to take a step =
