Hi,
I'm just trying to get OCL working with UML and having a few problems.
Below is the source and the exception trace that I keep getting. I'd
really appreciate it if someone could give me a quick hand. The
tutorials only illustrate Ecore metamodels and I can't find any simple
tutorials that shows you how to use queries over UML/Ecore. My uml model
is a simple one - at its root it has a Model and its packagedElements
are two packages. I thought passing in the .eClass() from the Model
element would work but it doesn't seem to. I tried this query on the OCL
console with my model and it works!
Thanks in advance,
Andrew
