Hi Marc, The easiest way is to set the default value at database level. If this way doesn't work for you, here's Cayenne 3 solution, maybe a bit ugly, but the one comes first to my mind: you can intercept low-level SQL query generation by implementing BatchQueryBuilderFactory (extending DefaultBatchQueryBuilderFactory). There you can plug your own InsertBatchQueryBuilder that will set certain fields for certain tables. BatchQueryBuilderFactory can be set via DataDomain.setQueryBuilderFactory.
Hope that works, Andrey 2010/9/30 Marc Guenther <[email protected]> > Hi, > > I have the usual flattened User <<-->> Group many to many relationship with > a association table in between.
