Are you using turbine 2.1? It's been fixed in cvs. The problem was with the call to copyObj.getBars(). When the copyObj is created, isNew is true. When getBars() is called, if the object is new, there is no reason to retrieve the bar objects ( since there shouldn't be any ). The fix was to set copyObject.setNew( false ), copy the dependant objects, then set copyObject.setNew( true ). Patch committed in cvs to turbine-2 and turbine-torque back on 10/19/2001.
Options: o Look into the archives on how to move up to cvs version of turbine-2 o Wait until 2.2 is released o Use stand-alone torque from cvs o Patch your copy of Object.vm, look in cvsweb on jakarta site for the change on 10/19, it is two lines of code: http://cvs.apache.org/viewcvs/jakarta-turbine-2/conf/torque/templates/om/Obj ect.vm.diff?r1=1.1&r2=1.2 ----------------------------------------------------------------- Jeffrey D.
