[Chen Dai]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:20.0) Gecko/20100101 Firefox/20.0
Build ID: 20130329030832

Steps to reproduce:

1. enable google talkback
2. open firefox
3. go to google.com
4. input "aaabbbcccddd" into input box


Actual results:

nothing happened


Expected results:

talkback should read "aaabbbcccddd" after input the text

I download the nightly builds, and I found this version "http://ftp.mozilla.org/pub/mozilla.org/mobile/nightly/2013/03/2013-03-16-03-08-54-mozilla-central-android/fennec-22.0a1.multi.android-arm.apk" works fine, but this http://ftp.mozilla.org/pub/mozilla.org/mobile/nightly/2013/03/2013-03-16-16-05-54-mozilla-central-android/fennec-22.0a1.multi.android-arm.apk" works bad

Created attachment 746832 [details] [diff] [review]
patch for bug869322

This bug is because:
after Bug 833164, accessible events cpp were replaced by code gen of xpcom.
The original textchange event had a funtion isInserted, but in the gen code, isInserted changed to a bool attribute.
In Eventmanager, it still calls isInserted(), so it throw a error

Thanks for the patch! In the next day or so, this patch will be merged on to mozilla-central and will be resolved FIXED at that time. Currently, this fix will appear first in Firefox 23. Eitan, should this be nominated for uplift? Seems like a bad bug with a low-risk fix.

One more request, to make life easier for those checking in on your behalf, please make sure that you have Mercurial configured to generate all the necessary metadata for checkin. Instructions are linked below. Thanks again!
