I am having some trouble with my associations. I want a user model and a person model to have a one to one relationship. So I click the association tool, click the person model, then click the user model. For the source class I use the UserID, and for the target class I put the PersonID. Thats all fine. Now my trouble is what to do with the Identity Mechanism, on my first run I left both of them on default. Well default works fine until I try to add a second item to the database and I get an error sayings I cant use the same primaryId twice. So I try changing both of them to DatabaseServerCalculation then I get an error telling me that wont work cause the foreign key for person is being generated by the UserID. So now I try to just leave the UserId as DatabaseServerCalculated and the PersonId as default and I get this error.
The statement has been terminated. ---> System.Data.SqlClient.SqlException: The INSERT statement conflicted with the FOREIGN KEY constraint "ref_User_Personal_Info_Bank_User". The conflict occurred in database "MyBank2", table "dbo.Bank_User", column 'UserId'.

Never mind, think I got it sorted out. It seems backendcalculating one object and leaving the other default works out just fine.. The problem was in a whole other object model, I had it setup so my user object was one to one with my person object, but my person object was one to one with a address object, and soon as I got rid of that address object it all worked fine. With a one to one object the parent object is generating the ID for the child object, but I guess it just gets confused when a parent object gives a id to a object that gives a id to another object.. I think... lol

Hi Kurt,
I am glad to hear that you have resolved the issue you encountered. In fact this scenario - modelling three tables with one-to-one relationship between them is possible with our Association Editor. If you still have any troubles implementing it please let me know so I can provide you with more detailed explanation of the process.
Should you have any further question please get back to us.
