Hi all,
Sorry if this is question has an obvious answer but I'm new to EMF/OCL and googling my issue didn't really help.
I'm developing a standalone application that loads a .uml model using the UML2 lib of Juno. This works as expected. My next step is to parse all OCL expressions inside OpaqueExpressions (OEs) of the model. Therefore I use Model Query to retrieve a list of OEs and try to setup an OCLHelper to parse the OCL body of the OE. Now it turns out that my OEs are inside guards of transitions and according to http://www.eclipse.org/forums/index.php/t/209674/ the OCL framework did not support parsing these kinds of OCL expressions, if I understood correctly. So I'm wondering whether this is still an issue and - if not - how I can parse the OCL found in an OpaqueExpression of a guard.
Thanks,
Willibald Krenn

Hi
It's current work in progress so you need to use the Kepler M1 release
of a N-build or GIT.
