Thks Armin I 'll try that . But in the documentation on a M-To-N relation or 1-N relation. When we are using auto-update = false ( aka link ) and auto-delete=false ( aka link ) .The referenced objects should not be updated nor inserted. But instances could be delete. It seems to be a bit weird to me. May be add a line in the Documentation for completing it depending of the kind of collections ???
Anyway thanks a lot for your support :) Thierry -----Original Message----- From: Armin Waibel [mailto:[EMAIL PROTECTED] Sent: Thursday, April 01, 2004 9:30 PM To: OJB Users List Subject: Re: Help M-To-N relation update => deletion of referenced objects . Hi Thierry, by default OJB use a removal aware collection, but in your case you shouldn't use it. Thus you only need to declare the collection within your collection-descriptor: <collection-descriptor name="favoriteFood" collection-class="org.apache.ojb.broker.util.collections.ManageableArrayList " element-class-ref="org.apache.ojb.broker.InterfaceFood" auto-retrieve="true" auto-update="true" indirection-table="GOURMET_FOOD" > <fk-pointing-to-this-class column="GOURMET_ID"/> <fk-pointing-to-element-class column="FOOD_ID"/> </collection-descriptor> regards, Armin Thierry Hanot wrote: > I've just tried with the last cvs version .
