Hi there,

i am stuck on a many-to-many relationship.
I have 'product' <->> 'prodcat' <<-> 'category', so this means
flattened: 'product' <<->> 'category'
now always if i try to insert categories ina product i get
following exception:
A valid global ID could not be obtained for entity named prodcat,
relationship named categorys, primary key dictionary {proID = 1;
catID = 1; }.
Does the middle entity (prodcat) have a database table assigned and
its keys have database columns defined? EOModeler doesn't add them by
default.
I have tried several ways, even without flattening the relationship.
I have the newest Version of WO and xcode, maybe that is the
problem...
Shouldn't be a problem. Something else is up (with your model).
with regards,
