I removed the beginInsertRows() and endInsertRows. I replaced it with an 'emit layoutChanged()' and now it seems to work. Is thier any downside to doing it this way? The insertRows() function I posted above was for test purposes only. Now that I can insert a row, would it be best to put a generic or blank record in and then go back with a setData() or just put the valid data in immediately? I'll be using a dialog to enter the new row.
