Hi Alex,
Yes you can do that. Validation routine is executed before object
changes are finalized, allowing arbitrary object operations to be
performed during the validation.

Hello list,
I am currently using Cayenne 2.0.
I read it was possible to modify objects during a validateForInsert
or validateForSave call (e.g. not the same as old WebObjects).
What about creating a new object and inserting it in the
DataContext? Will it get saved at the same time?
My problem is the following:
I have an object which has a to-one relationship to another object.
That other object has to be created at the same time as the first
one. I would like to make it automatic so the user of the library I
am writing can simply create and insert the first object and the
second one will follow.
To understand why I am creating two objects related one-to-one it
is because I have an entity which can be related (to-one) to either
one of four other entities. I am doing this instead of modeling
things with a class hierarchy since cayenne doesn't support
multiple tables class hierarchies.
Thanks for any hints!
Alex
