Well I just setup another with same code and it works. Does anyone have
suggestions on what kind of mistakes would cause a
java.lang.NullPointerException when using the this.db.deletePersistent
(toBeDeleted);. I've removed just this line and there's no error, so I
know it's a mistake in this area. Either with the object or mappings.
This object below has no collections or references in it.

I seem to be getting a NullPointerException when attempting to delete
an object. I do this "this.db.deletePersistent (toBeDeleted);" and I
get the exception. I've copied the same delete code to three different
objects and two of the three throw the exception. I've looked over and
over the code, but can't seem to figure it out. If someone has run
into this I'm sure it's a simple mistake. Any help would be great.
