I used the "Find Expression" tool by Versatools to look for references to a view name. It found a couple that I was able to locate and remove quite easily. However it found one that I cannot locate! it apears to be in a bizobject. The screen tells me that there are two instances of the 'v_authors' expression in 'contform2.pgfBizObj.Page3.Titleobj'
One is in the method postinithook. This was simple to find.
The other is in a Property: TextBox.ControlSource
When I double click on this line, a small screen is displayed with a textbox and two buttons (Save and Cancel) on it. The textbox displayes:

"v_authors.authorname" which is what I am searching for.

Above the textbox is a label:

"Edit Property [contform2.pgfBizObj.Page3.Titleobj.TextBox.ControlSource]"

I have not tried clicking on the cancel button yet <g> maybe it will remove the expression?

Can anyone give me some information on this? I don't know of a textbox in a bizobj.
TIA
