Subject Re: Update & OneToMany
Date Fri, 10 Aug 2007 15:06:52 GMT
Hi Esteve,

Doesn't sound normal.  Can you give us more info?  Some questions that 
may help you understand what is going on.

What are all the annotations for the OneToMany relationship?

If Entity1 has a simple value attribute and you update that, does the 
same behavior occur for the association?

Is it possible that you have assigned a new collection to your field, 
instead of modifying the existing collection?  If so, does the behavior 
change if you change your application to modify the existing collection?
