If I understand the following log entry then there was an error in reporting an error. Note this app uses no native JavaScript. Pure Java and GWT (2.5.1). I'm using gwt-log 3.2.1. I use
Log.setUncaughtExceptionHandler(); Or perhaps I'm misunderstanding but this entry doesn't seem to provide any useful information. 1. 2013-06-17 12:18:17.076 /expresser/gwt-log 200 58ms 2kb Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.0; Trident/5.0) 144.82.34.225 - - [17/Jun/2013:04:18:17 -0700] "POST /expresser/gwt-log HTTP/1.1" 200 2987 "http://web-expresser.appspot.com/e/index.html?model=iejpe002f&contextKey=IOE-PGCE-13-WL-1&activity=http://dl.dropboxusercontent.com/u/15433946/my-migen-activities/happyface-activity.xml"; "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.0; Trident/5.0)" "web-expresser.appspot.com" ms=59 cpu_ms=21 cpm_usd=0.000334 app_engine_release=1.8.1 instance=00c61b117c2146c8eb2b0bcd992b8617b42e77b6 <https://appengine.google.com/instances?app_id=s~web-expresser-hrd&version_id=519.368110279399075478&key=00c61b117c2146c8eb2b0bcd992b8617b42e77b6#00c61b117c2146c8eb2b0bcd992b8617b42e77b6> 2.
