Hi,
I'm modelling a series of database and objectentities and when I add one
of the relations and try to synch it, it asks if I want to remove
foreign keys mapped as object attributes, and I say yes and the CPU goes
into a spin and the heap blows up see stacktrace at end.
If I do the same again but tell it not to remove foreign keys mapped as
object atributes it works.
So, I don't expect you to give me any hints based on this. I find it
difficult to explain what I'm doing but is it okey to post an image
showing the datamodel and which relation I add when this is happening
or/and add the cayenne.xml etc. The I can more easily explain what I'm
doing. I haven't seen anyone post with attachments so far on this
userlist so I don't know if that is according to forumpolicy.
Cheers,
Tomas
