could anybody please help me with an OCL problem, which might actually be
very easy but I can't solve (I've just started using GME and never used
Having a "Container" model containing a number of "Contained" atoms (see
attached picture), I'd like to restrict the contained objects in case the
"value1" Integer field of "Contained" is 0 (zero) so that no other objects
may be associated.
What I came up with is the following constraint attached to the Container:
contained->exists(value1 = 0) implies
not contained->select(s | s.value1 <> 0)
Unfortunately, this doesn't work. The message I get says that the ocl::Type
(probably "contained") does not have an Iterator and is not compound and
secondly that "value1" doesn't exist.
Thanks a lot,
