You can, of course, write your own column class and map it to a particular type name, but that's a bit of an undertaking. If you just want to modify an existing column class, use column triggers: http://search.cpan.org/dist/Rose-DB-Object/lib/Rose/DB/Object/Metadata/Colum n.pm#TRIGGERS In this case, the inflate and deflate events are the ones you want. And yes, you can do this right in the column definition in your setup() call: http://search.cpan.org/dist/Rose-DB-Object/lib/Rose/DB/Object/Metadata.pm#ad d_columns "If the hash contains a key with the same name as a column trigger event type (e.g., "on_set", "on_load", "inflate") then the value of that key must be a code reference or a reference to an array of code references, which will be added to the list of the column's triggers for the specified event type." -John ------------------------------------------------------------------------- Take Surveys.
