Hi, I have a DB with this entinies: Cars and Accesories...
I need to do a to many relationship between this two entities
a Car can have many Accessories
I made the relationship with EOModeler without any problem, than added
in my accessiories component page a WOToManyRelationship binding the
relationshipkey with the name of the relationship, the sourceObject
with the accessiories object and the source entity name with tha name
of the entity accessiories.
Wen i load the accessiories compnent the WOToManyRelationship display
me the list of Cars that I can choose, correctly.
But when I submit the form I obtain an exception.
Can anyone help me with this?
Exceptions are important. They provide valuable clues as to what went
wrong. Try carefully reading all the details of the exception. Can
you spot the problem? If not, post the entire exception with stack
trace here and perhaps we can help. Otherwise we are just guessing.
