Steps to Reproduce Behavior

1. Create a new form.
2. Add a pageframe to the form.
3. Set the PageCount property of the pageframe to 0.
4. Create a new program file that contains the following code:

      SET PROCEDURE TO <this program>
      DO FORM <form name>
      _SCREEN.FORMS(1).PAGEFRAME1.ADDOBJECT("Page1","Page1")
      _SCREEN.FORMS(1).PAGEFRAME1.ADDOBJECT("Page2","Page1")
      _SCREEN.FORMS(1).REFRESH
   
      DEFINE CLASS Page1 AS PAGE
      ADD OBJECT command1 AS COMMANDBUTTON
      ENDDEFINE
   						

5. Run the program. A form with two pages should appear.
6. In the Command window, type:

       _SCREEN.FORMS(1).PAGEFRAME1.PAGE1.PAGEORDER=3
