Is it possible to write a join bolt that joins tuples from two different bolts, and automatically exposes the correct output fields ? For example: A--(x)-->Join--(x,y) B--(y)----^ Given bolt A that declares ("x") as an output field, and bolt B that declares ("y") as an output field, how would I code a reusable Join bolt that auto-magically returns ("x","y") as the output field. thanks, Itai ---------------------------------------------------------------------- This message, and any attachments, is for the intended recipient(s) only, may contain information that is privileged, confidential and/or proprietary and subject to important terms and conditions available at http://www.bankofamerica.com/emaildisclaimer.
