Hi,

I have the following problem: I set the default value to a parameter using the set command:


SetCommand.create(editingDomain, parameter, UMLPackage.eINSTANCE.getParameter_Default(), defaultValue)


and it's working ok, but when I try to undo, I've seen that the unsetDefault (of ParameterOperations) is trying to do this:

parameter.eUnset(UMLPackage.Literals.PROPERTY__DEFAULT_VALUE );


though the PROPERTY__DEFAULT was not set -- I thought maybe I should set this feature also, but it does not work like this.
And my problem is that it searches for this feature - Property__Default for the parameter, and it does not exist, so the "undo" throws an nullpointerexception.
FYI:

at org.eclipse.uml2.uml.internal.impl.ParameterImpl.eUnset(Para meterImpl.java:1598)
at org.eclipse.emf.ecore.impl.BasicEObjectImpl.eUnset(BasicEObj ectImpl.java:1156)
at org.eclipse.uml2.uml.internal.operations.ParameterOperations .unsetDefault(ParameterOperations.java:292)
at org.eclipse.uml2.uml.internal.impl.ParameterImpl.unsetDefaul t(ParameterImpl.java:834)

at org.eclipse.emf.ecore.impl.BasicEObjectImpl.eUnset(BasicEObj ectImpl.java:1156)

So is something that I might have missed on doing on setting the parameter default value?

Thanks,
Ioana

Ioana,

That looks wrong to me. I think it should be

public static void unsetDefault(Parameter parameter) {

if (parameter.isSetDefault()) {

parameter.eUnset(UMLPackage.Literals.PARAMETER__DEFAULT_VALU E);
}
}

Try changing it to see if that fixes the problem and then open a bugzilla.
