I have a working implementation which produces stack traces representing the original Jave source code when Javascript exceptions occur in web mode. I plan to deploy this in production on my site, typeracer.com in my next release.
I'd like to polish up my implementation over the next few weeks, measure performance, and present it at Google I/O at the end of the month. We've talked about adding similar features to the GWT compiler in the past on this forum, but my site couldn't wait (I was getting too many cryptic exceptions logged from users), so I decided to go ahead and do it my way. I ended up doing it externally to GWT, without any changes to the GWT compiler or any other code. Are there any new developments on this front in the core GWT code? --~--~---------~--~----~------------~-------~--~----~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~----------~----~----~----~------~----~------~--~---
