Hi all,

I have a metamodel
class Category
	{
		attribute name : Name[1];
		attribute term : String[1] { derived transient volatile }
		{
			initial: name.toString().toLowerCase();
		}
        }
....
datatype Name : 'java.lang.String' { serializable }
		{
			annotation _'http:///org/eclipse/emf/ecore/util/ExtendedMetaData'
			(
				pattern = '[a-zA-Z][a-zA-Z0-9]*'
			);
		}


I create a conforming model (Catergory name="Xyz")
The term is generated automatically "xyz"

However, during the validation I have this error

org.eclipse.ocl.pivot.internal.delegate.OCLDelegateException: The feature 'pivot::TypedElement::type' of 'self.name.toLowerCase()' contains a dangling reference 'String'
The feature 'pivot::TypedElement::type' of 'self.name.toLowerCase()' contains a dangling reference 'String'

Hi

I cannot reproduce in my workspace. But dangling reference is bad. Looks rather like https://bugs.eclipse.org/492255 which is fixed in the oxygen M1 (and later) milestone builds. However the bug concerns TypeExp, typically oclAsType arguments that are missing from the partial example that you have shared. I suspect the full example may be more instructive.

Regards

Ed Willink

Thanks Ed,
This exception only appears with dynamic instance.
However, when I generate EMF projects codes(core, edit editor, tests), I run the runtime Eclipse, and I create the same example,
this exception doesn't appear.
