[jboss-user] [JBoss Seam] - Re: editing part of a business key with seam framework

[koenhandekyn]

i totally redid the job with a clean entity bean and clean home and query components.

i have put log statements in the setters for the composite key fields and can CONFIRM that they are called

it should be noted that the 'not updating" issue only apears for changing field values. i can perfectly use the standard pages to CREATE a new entity.

more strange behaviour: when i update both a key field and another field at the same time : i DO get an exception:
