data object getLinks

Hi all, Hope this doesn't sound too strange. Does getLinks() support MULTIPLE, UNIQUE links to the same table? That is, pointers to different instances. In my case I have a Reservation table which has columns for two trains holding foriegn ids, which indexing a Train table. (This represents a 2:N relation. Since the 2 is fixed by the real world, I saw no point in an M:N table when two columns would do it.) CREATE TABLE tReservation ( tTrain_id_1 smallint(6) NOT NULL default '0', tTrain_id_2 smallint(6) NOT NULL default '0', ... ); CREATE TABLE tTrain ( trainId smallint(6) NOT NULL auto_increment, ... ); I have experimented with something like this in the links table [tReservation] tTrain_id_1 = tTrain:trainId tTrain_id_2 = tTrain:trainId but it's not reliable. getLinks() is working well in other parts of this same system, but I wonder if I'm abusing it here. Perhaps I need to override getLinks to explicitly do those two loads? Thanks, -- Mitchell Perilstein mitch at enetis dot net www.enetis.net/~mitch
