OVC Restriction on Public Form = Unknown Exception

This is really starting to irk me. Once again, I'm getting an "Unknown
Exception" when setting the Restriction on an OVC.

'****************************************************
Set vfolder = HostFolder.Folders("Account Products")
Set vfolder = vfolder.Folders("Notes")
Set myView = Item.GetInspector.ModifiedFormPages("Support
Notes").Controls("SONotesList")
myView.DeferUpdate = True
myview.Folder = sObj.returnfolderpath(vfolder)
myview.view = "SalesOutlook List"
myview.Restriction = "[AProductID] = " & "'" &
item.userproperties.find("AProductID") & "'"
myView.DeferUpdate = False
Set myView = Nothing
'****************************************************

It errors out on the Restriction line. If I comment it out, the OVC
shows the correct folder. The "AProductID" is defined correctly. It's
at the folder level and appears in the ONE item that is contained in
the folder (it's a brand-new folder).

What is going on with this thing?

I'd appreciate it if the responder could do so at my original post

I found someone else had this problem a year ago on this group:
