That's sounds like a good practice worth of documenting (hint ;) Couple of comments: > Due to how Cocoon processes, I do all processing that I know might generate > exceptions inside Actions, so the handle-errors pipeline can catch them.

Transformers with side effects (sql, ldap, xmldb, etc) can be implemented not to fail hard with exception, but return an element containing error which occurred. Then following stylesheet can process result of transformer and output appropriate message. (IIRC, XMLDBTransformer outputs success/failure result as an element). > If you're lucky, and do you do get an error > once the pipeline has started, as long as the response has not been commited, You can increase your changes (and decrease perceived performance) by boosting serializer buffer size. > you can still get a redirect to the handle-errors pipeline safely. > -pete Vadim > -- > peter royal -> [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
