I have also noticed this in 1.7.4 with the document database too. If I
change a property name (using ALTER CLASS .. NAME ....) the data in that
column is lost. If I change the column name back to the original name, the
data is back.
Its almost like it is creating a new column instead of changing the
existing one.
Very strange...
