Norman Richards commented on JBSEAM-4057:
-----------------------------------------

I don't understand what problem you are trying to solve.  Could you explain the problem you are seeing and why you your solution is general enough to be added to seam-gen.  I can't figure out what you are getting at from this JIRA.

> Constructing an EntityHome object really doesn't provide a completely-initialized object. I needed to create EntityHome objects around existing @Entity objects. Once created, these objects can be saved in the database. I created a new static method in the code generated by EntityHome. It's called wrapInstance and , in use, is defined as:
> static public MyTblHome wrapInstance(MyTbl dat);
> If there's an id in the MyTbl instance, it is used. Otherwise, an id is created and used.
> I also changed update and persist:
> If we get there with a null instance, it's an error so we return "invalid".
> There are commented locations for pre- and post-update code. For example, the code can automatically save the ID of the user performing an update.
> There's a catch for validation errors (hibernate InvalidStateException instances). If one is found, all InvalidValue lines are logged and captured foe message output.
