Problem with navigable owned end [message #473640]

Hi all,
I'm working at an UML model from which I want to generate by genmodel the
relative code. I have an association that owns a navigable end, that
corresponds to an attribute of the class at the opposite side of the
association. The problem is that the attribute ceases to exist whenever it
becomes an association navigable end. This leads to a genmodel completely
unaware of that attribute, situation I would like to avoid. How can I get
both attribute in the class and navigable end in the association?

Thanks in advance,
exquisitus

exquisitus,

Only properties owned by classes will result in properties since the concept
of an association does not exist in Ecore (EMOF). Properties owned by
classes are implicitly navigable, so if you're looking for a navigable
association end that's owned by a class, there's no need for it to be owned
by the association (nor for it to be listed as one of the association's
navigable owned ends)...
