I was trying to map a QLineEdit, but I'm guessing this is not supported with the mapper. I have it working now but I had to combine two SQL tables, which I was trying to avoid. I'm guessing there might be a way to get a QComboBox to behave more like a QLineEdit, but I'll have to come back to that later.

Another interesting feature is that the mapper looses it's index after submits and commits. The work around is to save the index before hand and then reset it after all submits/commits.
