/*!
Applies \a values to the \a row in the model. The source and
target fields are mapped by field name, not by position in
the record.
Note that the generated flags in \a values are preserved
and determine whether the corresponding fields are used when
changes are submitted to the database. The caller should
remember to set the generated flag to FALSE for fields
where the database is meant to supply the value, such as an
automatically incremented ID.
For edit strategies OnFieldChange and OnRowChange, a row may
receive a change only if no other row has a cached change.
Changes are submitted immediately. Submitted changes are not
reverted upon failure.
Returns \c true if all the values could be set; otherwise returns
false.
