Hi Kevin,
I changed the cmdNew.Click() to:

ThisForm.SetPrimaryBizObj(This.Parent.Parent.Page2.DespachosUpdateBizObj)

DODEFAULT()

ThisForm.SetPrimaryBizObj(This.Parent.DespachosGridBizObj)

The problem now is that the Focus is not going to the "Details" Page.

Regards,

If so, you can either have your button call the child object directly, or dynamically switch the primary business object to your UpdateBizObj.
