[news.eclipse.modeling.gmt.amw] Cannot assign model elements to weaving

["medo samh" <mdsamh@xxxxxxxxx>]

Hi,




I have the following two simple models conforming to km3.



Model A



      class A {

            attribute a1 : String;

            attribute a2 : String;

      }



Model  B



      class B {

            attribute a1 : String;

            attribute a3 : String;

      }



I would like to create a weaving model with a minimum set of elements 
(model, modelRef, link, linkEnd and ElementRef).



I have extended amw_core metamodel as follows:



package class_diff_ext {



class CModel extends WModel {

    reference CleftModel container : WModelRef;

    reference CrightModel container : WModelRef;

}



class ModelRef extends WModelRef {

}



class ElementRef extends WElementRef {

}



class AttributeAdded extends WLink {

   reference from container : LinkEnd ;

   reference to container :  LinkEnd ;

}



class LinkEnd extends WLinkEnd {

}

}



I have used the wizard to create the weaving model.  In page 1/3 - I have 
loaded the metamodel from the workspace. In page 3/3 - I have selected 
"ModelRef" and "DefaultWovenPanelExtension" because I do not want to work 
with XMI ids.




The first time the weaving panel is displayed, I get an internal error in 
the log saying that "Resource /amw_test/amw_test.ecore is not local" in 
org.eclipse.core.resources plugin.



In spite of the message, I can create a weaving link and can create a link 
end.  But when I try to assign an element from the left or right model, I 
get two errors

"Unhandled event loop exception" and the second is 
"java.lang.NullPointerException" with the stack trace below.



I am using Eclipse 3.2.1, EMF 2.2.1, AMW (Feb 16, 2007) and ATL/AM3 (Feb 16, 
2007).



Thanks in advance for your help,
