Hi Tim, may you or Rudy take this? Thanks.

Look like bug 952078. Jan, do you have cycles to address this?

I'll take a look this week.

[Solution] 1. Send the next key after the promise returned by the previous sendKey() invocation is resolved. 2. In order to also solve bug 987809, we should send the correct keyCode based on the right capitalization state (also after the previous promise is resolved). For this change, I think keyboard.js should pass to the input method with a keyObject which contains both the lowercase and uppercase keycodes. This should be easier to give feedback based on, https://github.com/mozilla-b2g/gaia/pull/19856/files?w=1 Tim, could you please help feedback on the above approach? Thank you.

Comment on attachment 8432204 [details] WIP - pull request 19856 With a offline discussion, I am convinced this is a valid 1.4/2.0 solution to the problem. I would like to see proper fix (a queue) implemented in keyboard app itself and not the IME. I have made some comments on Github to see if we could get a better clarity of this addition.

Comment on attachment 8432204 [details] WIP - pull request 19856 Patch updated to address the review comments. Tim, could you please help review this again? Thank you.

Comment on attachment 8432204 [details] WIP - pull request 19856 Hi Tim, Patch updated for: 1. Separate the 2 then() functions to make the code easier to read, and add some comments for the handling sequence. 2. I found we still need to return the promise in click(), or in the tests, we could not know when the clicks have been processed. 3. It seems that in handleKey() function, we already handle the case when inputContext.sendKey() is rejected, however, for safety, I also add a empty function as the onRejected paremeter to the 2nd then(). Please help review it again and thanks for your patience.

Landed to Gaia master, https://github.com/mozilla-b2g/gaia/commit/f0a8ab7d0b6000cc2c2cd2a201964bafa959858b Tim, thanks for the review.

Needs a branch-specific patch for v1.4 uplift.

I have a patch for v1.4 branch, however the Travis CI always failed recently. Working on bug 1023741 and bug1023694 to get it green again. Keep the ni so that this will be in my queue.

Uplifted to v1.4, https://github.com/mozilla-b2g/gaia/commit/8d528bba5fc29b674bdef21f5133967996614c37 The travis CI is green, https://travis-ci.org/mozilla-b2g/gaia/builds/27371939
