Is there a good example of how to use composite-id keys?

I have managed to read objects with composite id values from the database but cannot save a new one back to the database.

The documentation says that you implement Interceptor.isUnsaved() but gives no details. When I added this interface to my class I found that the method was never called.

I did find that calling save() directly did persist the object to the database.

You do NOT implement Interceptor.isUnsaved() on the persistent class. You implement it in an Interceptor. Please see the documentation.

Thanks, I implemented my own instance of Inceptor.

The method is correctly called on a SaveOrUpdate() passing the object I whish to persist as a parameter.

Now all I have to do is return a TRUE or FALSE.

But how do I do that with out exposing the innards of my object to Inceptor (and hence the rest of the word).......Could add a isNew() method I guess.


Oh, for an example, How much time one could save!
