Forms 4.5 and OCX

I'm trying to integrate a TreeList OCX control in Forms4.5. I get error "FRM-41344: OLE object not defined for {item name} in current record" at run time (on statement FORMS_OLE.GET_INTERFACE_POINTER ... ) Using Oracle White Paper [Quoted] "...Integration of OCX Controls..." I tried the sample tabstrip_ocx and get the same error. Support had a fix to issue synchronize before get_interface_pointer command; same results. I'm totally ignorant of OLE and OCX so I'm swinging in the dark. The sample shows creating the OLE container (from control), setting 4 properties and then getting the interface pointer, the collection and then issuing arguements. When is the actual object created or instantiated? Anyone have a working sample of a tree control (or other) OCX with Forms 4.5, or point me to a good source? Thanks.
