I have a problem with remove and relation on jboss 3.2.6. (was working on 3.2.3)
I would like to know if I made a mistake or if this is a bug I need to report :
I have 2 ejbs in relation :
One 'Parent' which has 0 or 1 'zeroOrOneChild'. My problem is that a call to remove on
Parent fail with a NoSuchObjectLocalException if the relation is null (Parent has no
zeroOrOneChild).
the ZeroOrOneChild table has a field idParent matching with its associate Parent
(forein key).
Here is my relation :
<ejb-relationship-role >
|
<ejb-relationship-role-name>Parent-facmp20-has-zeroOrOneChild-facmp20</ejb-relationship-role-name>
| <multiplicity>One</multiplicity>
| <relationship-role-source >
| <ejb-name>Parent</ejb-name>
| </relationship-role-source>
| <cmr-field >
| <cmr-field-name>zeroOrOneChild</cmr-field-name>
| </cmr-field>
| </ejb-relationship-role>
Parent.getZeroOrOneChild() can have a null value (I guess there is nothing special to
set into the descriptor)
and the log and stacktrace when removing Parent with idParent=65558 and which has no
ZeroOrOneChild :
2004-11-03 17:54:27,620 DEBUG [myapplicationlog] remove Parent

I understand that Jboss is looking for an element on 'ZeroOrOneChild' which has a
idParent matching with the parent to be removed.
But as this is a 0..1 relation it should not throw an exeption if no object is found,
should it ?
Thank's.
Nicolas FRANK.
