Hello,
I get a NullPointerException with the syntax helper when one of the typed
element has a undefined type.
For example, my class A has a property p. The type of p is not defined. I
select the class A, use the console OCL interpreter, ask a completion with
'self.' It triggers:
Caused by: java.lang.NullPointerException
at org.eclipse.ocl.uml.UMLReflectionImpl.getDescription(UMLRefl ectionImpl.java:92)
A quick look at the source gives:
org.eclipse.ocl.uml UMLReflectionImpl
//...
public String getDescription(Object namedElement) {
if (namedElement instanceof TypedElement) {
return ((TypedElement) namedElement).getType().getName();
}
//...
}
Now I am not able to state if its a bug or not, because I don't know how to deal
with a undefined type.

Hi, François,
In UML, TypedElements can be well-formed without having a type. The syntax
helper should handle this more gracefully, probably by showing some kind of
"(untyped)" string or such.
This is a bug.
Cheers,
Christian
