ELMAH Not Handling Errors on ASP.NET Async Page EndEventHandler Callbacks. #293

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Sorry if this has been handled already, or if not ELMAH's but ASP.NET's problem 
(see Atif's response in this thread from 2006:  
http://groups.google.com/group/elmah/browse_thread/thread/100fd880973e59c8?pli=1
).  I can't seem to find any discussion on this subject other than the above 
thread, yet I'm not sure from thread discussion what to do to fix the problem.  
I've tried throwing an HttpException and an HttpUnhandledException, though I 
don't seem to be getting anywhere.  I would appreciate any updated knowledge on 
the subject or workarounds available.  Thanks!

What steps will reproduce the problem?

1. Async Page (@Page Async="true"...)
2. Call AddOnPreRenderCompleteAsync(BeginSaveTask, EndSaveTask);
3. In EndSaveTask, get "Fault Exception" from async web services call (some 
null ref exception on services side for example).

What is the expected output? What do you see instead?

I would expect to see ELMAH error page, however I see yellow ASP.NET 
"unhandled" error page instead.  When I use the synchronous version of the same 
method, I see the ELMAH error page as I'd expect.
