Re: [Dynapi-Dev] A handy DEBUG method

[Jim F. <jf...@tm...>]

I have been doing something very similar. I have thought about taking it to
the next level and making it so that errorHandler actually sends the message
(url,lno,msg) to me (the developer) via e-mail in the background, but
returns true to the application so that the user is unaware that an error
occurred. This way once the application is deployed I can keep a pulse on
errors in the real world and take care of errors missed in the testing, yet
the user is not hindered since all of this notification happens in the
background.

Any thoughts on implementation?

Jim
