| Dear all,
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; }.
I have tried several ways, even without flattening the relationship.
Normally i would like to use a WOCheckBoxList on each product to set the categories. with selection: 'product.categorys'
I have set all necessary attributes like cascade delete rule, own destination and propagate primary key for both entities showing to the join table.
Is this a bug in WO?
If yes, how do i do it???
I have the newest Version of WO and xcode, maybe that is the problem...
Please help!
Thanks in advance Christian |
