Hello all, I am working with a legacy database where pretty much all the primary keys are strings and user defined. I'm using Grails to build out the front end to the underlying database (Rocket UniVerse and my own customized dialect for U2). Using GORM I can map columns and rows fairly easily and view all the data, the problem starts when I want to add a new record, I get the message below: Executing action [save] of controller [onemoretest.CustomerInfoController] caused exception: this id generator generates long, integer, short; nested exception is org.hibernate.id.IdentifierGenerationException: this id generator generates long, integer, short Which of course is because I am using user defined string via "id generator:'assigned', column: "@ID", type:'string'" in my domain. My question is this, where can I override that behavior. It would be great to do it in my dialect so as not to break other unknown things elsewhere. Thanks, Norm
