Thanks. Looks like my decision to add to the already generated code was a bad idea. I like your idea of simplifying. So that brings me to a design question: In this case should I create a new SLSB to persist the new person record rather than the generated PersonEditorBen(SFSB)? If I do create a new SLSB, can I make it do the room lookup, extract the data from jsp and add the record to the person table. Or, does this SLSB need be to specifically for the room lookup? If so, do I always need to user SLSB when doing fancy dropdown lookups on tables? In Seam what are the best guidelines for determining when/when not to use SLSB/SFSB?
