I'm not sure if this page will help at all: http://cayenne.apache.org/doc20/modeling-inheritance.html
Also, could you show us the SELECT that is issued when you try query a KlassB? Thanks! /dev/mrg On 2/26/07, Nick Peeples <[EMAIL PROTECTED]> wrote:
I do have the Qualifier filled in. Everything that is online in either the user doc or the modeler doc is currently being done, that is why this is confusing me a little bit. A little bit more, the objects that are in the cache are even not being subclasses properly either. Just poking around a bit, if I do a: return (KlassB) DataObjectUtils.objectForPk(context, obj.getObjectId()); on an object that i know is of KlassB extends KlassA, it gets an Cast error. The obj was put in the cache by a: SelectQuery query = new SelectQuery(KlassA.class); Not sure if that helps at all. -Nick On 2/26/07, Michael Gentry <[EMAIL PROTECTED]> wrote: > Make sure in Cayenne Modeler, under the ObjEntity (Entity tab) for > your subclasses, you have the Qualifier filled in.
