Dear all, in Helios, literally all my UML models no longer validate,
including trivial new ones. For example, in the Helios Modeling Tools
release, I create a new UML model with the following structure:

+ Model
+ Statemachine
+ Region
+ Transition

Selecting "Validate" in the UML editor will then yield:

"The opposite features 'owner' of '<Trigger> s' and 'ownedElement' of
'<Transition> k' do not refer to each other"

Likewise, in the OCL console, on the transition, querying for 'trigger'
will return the trigger, but both 'ownedMember' and 'ownedElement'
return an empty result set (which is why the validation seems to be

I'm observing this on two different Helios installations (MacOS MDT
20100617-1415, Solaris x86 3.6RC4).

Thanks in advance for any clues as to what I'm doing wrong!
