Syringe.Net.Nz - Xero Error handling. Errors in your pages are bad. Errors in your Error pages are REALLY bad.

Xero Error handling. Errors in your pages are bad. Errors in your Error pages are REALLY bad.

Whoops! Got to Xero this morning and got this.

Looking at the address bar it appears that it’s sent me to the custom error page. And then the custom error page has thrown an unhandled exception which has been bubbled to the default error handler.

If ever there was a case for using ‘On Error Resume Next’ then Custom ASP.NET Error pages are it . Throwing an unhandled exceptin from your nice Custom Error page gives bad UX.

On the plus side, the Xero support people are just super and the actual application really rocks too.

D'oh! Oh well, at least it didn't display a stack trace and violate my own rules :)

Good catch! (Though I think we fixed it about a minute after you blogged about it!)

Some changes that happened during this release cycle didn't get made in the custom error pages - it's one of those things you don't always think about until it happens and we tend to do our full QA cycle with full error traces on so our QA team can log detailed issues.

Thanks
