Why is it not ProductLocal then? -----Original Message----- From: Schildmann,Ingo [mailto:ing...@ba...] Sent: Wednesday, April 30, 2003 10:51 AM To: 'xdo...@li...' Subject: RE: [Xdoclet-user] valueobjects and 1-to-1 aggregation Thanks, but I'm already using Locals. If I understood the example correctly, example.interfaces.Product is a local interface. Is the solution maybe not to integrate the aggregation into the = valuobject? Ingo > -----Original Message----- > From: Mic...@ub...
