yes i agree. my error checking is going into a buisness level helper class (instead of the form) because it is so complex. it onvolves going into the database, and making sure there are a minimum number of an item left, before a user can make changes to it. it also needs to check various other attributes from the db. i thought that this was too cumbersome to be in the form.
andrew mentioned some ways to forward back to the form with an error in 1.1. i am using 1.0, will these techniques still work? are there any other suggestions on how to do this in 1.0? unfortunately i need to stick to 1.0, so suggestion to upgrade are not going to help much :-) thanks, -mark -----Original Message----- From: David Graham [mailto:dgraham1980@;hotmail.com] Sent: Monday, October 28, 2002 10:38 PM To: [EMAIL PROTECTED] Subject: Re: error checking in Action Nice restatement Rob. That's exactly how I see the validation working. I know I'm in trouble when my action class gets too big :-).
