Right - but this is strange - why it is changed at all? I retrieve my row and I don't even show these fields in my view - so why is it changed anyway?
Could it be I am doing something wrong?
Also, may be I can put the fields in the view as readonly textboxes - may be it will solve the problem?
If it's not broken, fix it until it is.
