Place family workplane problem

I have a problem with placing family with Dynamo in Revit. When I place a family with Dynamo the Work plane parameter is locked of the revit element. And when I use the node element.setparameterbyName, I get the message workplane is read only. The problem occurs with workplane based family’s. how can I solve this?! [Knipsel][Capture]
