Hi Mat,

Thanks for the suggestion. Both pages of the pageframe use the same bizobj. I had it placed on page 1 of the pageframe as suggested in the manual (page 116). I moved it from page 1 and placed it on the form itself and it shows up on the Property List ahead of oSessionenvironment and its associated 'refbizobj' which doesn't look correct to me. Shouldn't the oSessionenvironment be the first thing on the list? However, when I ran the form the same error occured.

I selected 'Tab Order" and select the oSessionenvironment and its loader as #1 & #2 with my bizobj as #3 and the pageframe as #4 but it did not change on the Property list. I also selected the oSessionenvironment and 'Sent it to the back', then selected my bizobj and sent it to the back. Still the same sequence.

Could the 'Unknowwn Member oBehavior' error be a bugus error of some type or relating to some other control. I have not added any additional controls to the class as included in cform.vcx?

Thanks again Mat.

Bill
