Tapestry Exceptions again....

[Graeme Knight <gk...@bluecatnetworks.com>]

Hi.

I've not looked into this for a while, but perhaps someone can help... We are using Tapestry for a large project. There will be a lot of code and a lot of pages. Errors will definately occur and I want to make sure the turnaround in finding and fixing them is short. When I do something stupid (for example, set an identifier as null in a method then try to use that identifier for something meaningful, I get the stacktrace as below). Are there any methods/listeners/anything I can make use of to get a more accurate picture of the problem, and further infomation about where in my java page code the error happens (I need more than com.bluecatnetworks.proteus.web.pages.AddFirewallRulePage@3c35fd[AddFirewallRule]: null)?

Many thanks for any help,

Rgds, Graeme.
