Re: Deletion Bug!!!!!?
hi tino, i agree this behaviour is dangerous and it should _not_ be the default behaviour. i would also like the collection to be insertion-aware. but i think these features are already implemented in odmg-api; so we kinda duplicate functionality here. jakob TINO SCHÖLLHORN wrote: Hi Olli, and what about changing the default behaviour again? Honestly I think it is pretty "dangerous" because when I want to remove a relation I just want to remove this relation. It is another thing when I remove an instance of a class - then the default behaviour could delete the relations as well - but the deletion of the main-instance when removing a relation to it is really discomforting.

Hello, -Original Message- thanks - I think that was the solution. But I don't think that it was intended by the developers of OJB that OJB deletes instances by default, or was it? no it was not, so OJB did not do it. Then a lot of users complained, so we changed it. That was probably a mistake. Now it is one of the most frequently asked questions. Just search the mailing list archives for 'RemovalAware' or the like.

Re: Deletion Bug!!!!!?
Always the same question, I ask it few days ago ! First you need to configure your repository (with auto-delete="false"), i think you've already do this. Then use the ManagedArrayList as a collection class (by default it's a RemovalAwareCollection) like this (as an a attribute of the collection descriptor element): collection-class= "org.apache.ojb.broker.util.collections.ManageableArrayList" - Original Message - From: "TINO SCHÖLLHORN" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, November 27, 2003 3:57 PM Subject: Deletion Bug!? > Hi, > > I have a really weird problem and I don't if I am doing something wrong or > if this is a bug of OJB. > > I have basically 2 classes: Person and Department.

Deletion Bug!!!!!?
Hi, I have a really weird problem and I don't if I am doing something wrong or if this is a bug of OJB. I have basically 2 classes: Person and Department. I defined a N:M relation between those two. Now I want to remove a Department from a Person. But what happens is, that OJB is trying to delete ALL relations to other classes and is then deleting the Department as well!!! Do I have to change my configuration? Or is this a bug? In hope for help. Tino - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
