Sid, I checked the diagnosis. It says the layout of the element tc_declare (flow_data) is different from the layout manager of its contatainer ROOTUIELEMENTCONTAINER (GRID_LAYOUT). In the system where it is working the layout of both the element TC_DECLARE and ROOTUIELEMENTCONTAINER is both (FLOW_DATA). Should I change both to Flow_data layout? Or should I change TC_Declare to Grid_layout? Many many thanks for your help!
