Helo,
I am working on a project which combines EMF + GEF. The project worked
until I changed the metamodel (extended with a node and some
relationships). Corresponding classes (EditParts, EditPolicies ...etc)
are also created for to enable the created GEF based editors.
Anyway, the problem I have is created because of the code:
Roots2modelPackage.init();
I have tried to test the generated code in a test class, which passes
through (at least) this line without problem.
Any ideas why EPackageImpl cannot initialize my package?
PS! When I call the following 2 lines before the problem line, the
second one initiates the object "roots" with all its contained objects
(which are assigned null).
(1) roots = Roots2modelFactory.eINSTANCE.createROOTS2Model();
(2) rootsModelFactory =
Roots2modelPackage.eINSTANCE.getRoots2modelFactory();
(3) Roots2modelPackage.init();
Thanks in advance!

Adrian,
This line makes me suspicious:
java.lang.ClassNotFoundException: ecore.EcorePackage
There isn't such a class so where is this dependency coming from? Do
you have a spurious generated_package registration in some plugin.xml
that registers the above bogus name to the Ecore namespace?

This line makes me suspicious:<br>
<blockquote>
<pre wrap="">java.lang.ClassNotFoundException: ecore.EcorePackage</pre>
</blockquote>
There isn't such a class so where is this dependency coming from? Do
you have a spurious generated_package registration in some plugin.xml
that registers the above bogus name to the Ecore namespace?<br>

Helo,
I am working on a project which combines EMF + GEF. The project worked
until I changed the metamodel (extended with a node and some
relationships). Corresponding classes (EditParts, EditPolicies ...etc)
are also created for to enable the created GEF based editors.
Anyway, the problem I have is created because of the code:
Roots2modelPackage.init();
I have tried to test the generated code in a test class, which passes
through (at least) this line without problem.
Any ideas why EPackageImpl cannot initialize my package?
PS! When I call the following 2 lines before the problem line, the
second one initiates the object "roots" with all its contained objects
(which are assigned null).
(1) roots = Roots2modelFactory.eINSTANCE.createROOTS2Model();
(2) rootsModelFactory =
Roots2modelPackage.eINSTANCE.getRoots2modelFactory();
(3) Roots2modelPackage.init();
Thanks in advance!
