Hi
When reporting OCLinEcore issues, it would help if you use OCLinEcore
syntax, so that it can just be cut and paste.
I presume you mean
package Model1 : pfx = 'http://Model1'
{
class A {
property refFromAtoB # refFromBtoA : Model2::B {composes} ;
}
}
package Model2 : pfx = 'http://Model2'
{
class B
{
property refFromBtoA # refFromAtoB : Model1::A;
}
}
with Model1 and Model2 in separate files.
Well that gives me lots of trouble. The main problem is that the edit of
the Model1 file is just that. It should be a joint edit of both models
so that the save updates both.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=383259 raised.
Stylistically, a cyclic reference between models is not a particularly
good idea. Put them in the same file.
