I've got an object model with strongly typed collections:

class BList implements Collection { ... }
When I store the object, everything is good, but when i read it later i've
got an exception
thrown from AbstractPersistentField.set when trying to set the B collection,
which is a
ManageableCollection.
IMO the is caused by the fact that you Blist attribute is now filled with a ManeageableCollection and not with BList!
You have to tell in the collection-descriptor that the "bs" attribute must use a special collection-class="BList".
To make this work You BList must implement the interface o.a.ojb.broker.ManageableCollection.
See tutorial 3 for more details.
OJB was configured to use PersistentFieldDirectAccessImpl.
So i tried with PersistentFieldIntrospectorImpl and adding a set method public void setBs(Collection list) but I've got the following exception: Can't get WriteMethod for property:bs in object:A
Is there a way to store and read my collection without writing a custom PersistentField ?
IMO this is only a secondary error!
cheers, thomas
