I am using a relationship update cascade and a .Update method to update reocords. Since I added in the update cascade the records are being entered in the table and then for some strange reason all the PK/FK fields are deing deleted again ? ANy odeas what is going on. I'm sure its to do with the relationship but how do I avoid it. I thought using the update cascade would add the new records FK fields to the second table - is this wrong ?
