Hey Jim,
That error is: 16395 Error Profile object already exists.
What does the profile definition look like? You haven't altered the schema
and made PageGroup a key in the TargetingContext profile definition, have
you?
The key should be a unique id (GUID) value. Each unique request and thus
unique instance of CommerceContext.Current should generate a new GUID value
for that when you access CommerceContext.Current.TargetingSystem (a
TargetingSystemInfo object). It then calls CreateProfile with the newly
generated GUID and that profile instance becomes the
TargetingContextProfile for that request. Note that there should be no
backing store for these profile instances - they are in-memory only profile
instances. I suspect you're hitting a collision with another profile
instance already in cache on that machone somehow.

Subject: Setting the PageGroup gives an error on page refresh
Date: 13 Jul 2005 06:37:33 -0700
I have a page which displays a banner ad using the 'PageGroup'
functionality. All works, except when you hit the browser 'refresh'
button (or when a Postback is performed !). Anyway, the line which sets
the PageGroup fails.
Has anyone else seen this or can anyone eplain why this is ?
Thanks
Jim
