I have converted an SCX form to a VXC form class. All ran OK when the form was launched via a DO FORM.

However, when instantiating the same form as a class, a piece of show control logic as follows :-

if empty(thisform.cboTypes.Value)
   this.enabled = .f.
endif

Is giving the error "Unknown Member cboTypes".

If I further amend the code as follows :-

if pemstatus(thisform, "cboTypes", 5) <-- Returns True as the property exists - I can see it in the debugger too.
   if empty(thisform.cboTypes.Value) <-- Unknown Member cboTypes
      this.enabled = .f.
   endif
endif

So, this worked as an SCX but not in an unchanged VCX form. Any ideas what is happening here?

Thanks!
