Hi Guilaume,

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

        class A {
                private BList bs;
                public  BList getBs();
        }

        class B {
                ...
        }

        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
