This method is a pre-commit test of the active record. It compares
the current record data with the record data from the current data
source. If the data has changed, then this method returns true.
Note: The data connection methods xfa.sourceSet.DataConnection. first, xfa.sourceSet.DataConnection. next,
xfa.sourceSet.DataConnection. previous,
and xfa.sourceSet.DataConnection. last perform
an implicit update if the data has changed.
SyntaxReference_Syntax.hasDataChanged()

the data has changed, and false if the data has
not changed.
