@adrian
I was just checking your fm3.mse file... first of all; all files should
end in a newline so maybe you want your endDocument to print a newline
at the end...
Then I see that for opposites you do not specify derived anymore either?
Thats already good.
The container property you have, that is for identifying back links
right? If so... aren't all One's of a One->Many relationship back links?
Does anybody know of a metamodel where this is not the case? If not ...
maybe we could throw that out and infer this too?
cheers
