Hello everybody
I am trying to get the book/ebook/paper_book example to work with
Cayenne Modler 4.0.M3, but it wont validate. This is the third time I
try this and I really need to get this working now, I am not very keen
on a road block meeting and switching to another ORM.
I strugle with the relationships between superclass table and subclass
table. I set up two relation ships in BOOK
Name:"paperBook",Target:"PAPER_BOOK", To Dep PK:True, To
Many:False
Name:"eBook",Target:"E_BOOK", To Dep PK:True, To Many:False
I then first create the ObjEntities for all three. Then I enter the
type classifier field and set the inheritance. After wards I go to the
two subclasses and map the two individual attributes they posses to the
right subclass attribut. Then I save the project and the validation
tells me that that all the ObjRelationships have uncompelte mappings.
Example: "ObjRelationship book.eBook has incomplete DbRelationship
mapping"
I then go to Book ObjEntity and open both relationships to the subclass
once, but I change nothing. Opon closing I am asked if I want to save
my changes, because I some how have magically modified the path. I say
yes. Then I validat again and all but two complaints are gone. Left
over are:
"ObjRelationship EBook.book has incomplete DbRelationship
mapping"
"ObjRelationship PaperBook.book has incomplete DbRelationship
mapping"
Those are the relation ships pointing back from the subclasses to the
super clases. I can't fix them. When I open the edit dialog
Can please someone help me to find out what I am doing wrong? I kind of
feel stupid about asking here, because it is so trivial :/ But I really
need this working. If someone wants to have a look at my cayenne
project I put it on my drop box: https://www.dropbox.com/s/uw82cl1yxkl3

Best regards and thanks to everybody for helping
