[Solved] Grid no creating new record

[Charley]

We have a grid that ties to and object.  The problem seems to be that the object has nested objects.  This is stopping the grid from creating a new record once the add record button is clicked.  Is there any one who has a fix or suggestion for this problem.  We have initiated view models for this problem but since our object is a compound object it makes maintenance rather difficult.
the object look likes
mainobject
    propertyone
    proprtytwo
    subobject
         subobjectproprtyone
         subobjectproprtytwo

Thanks for the reply.
