If memory serves, the bug here is that we shouldn't be able to trigger copy/paste in the first place in the smartphone FTU

Tim, can you help out with this selection bug?

Ting-Yu, could you handle this? Thanks!

The root cause is similar to bug 1228151 where AppTextSelectionDialog is not being loaded as a component into FTU. To make copy/paste work, app needs to load AppTextSelectionDialog as a sub-component in [1]. I've tried to launch FTU though WebIDE, and copy/paste works as normal. I'm totally foreign to Gaia starup process. Does FTU being loaded differently when it's the first time use? Does FTU have sub-component mechanism so that AppTextSelectionDialog can be added? If we decide not to use copy/paste in FTU, FTU should set "-moz-user-select: none" in CSS so that no selection is possible. Hence no caret or dialog will show.

> If we decide not to use copy/paste in FTU, FTU should set "-moz-user-select: > none" in CSS so that no selection is possible. Hence no caret or dialog will > show. As I said in Comment #1, the bug here is that we already set -moz-user-select: none in the FTU, yet recently text has become selectable. See: https://github.com/mozilla-b2g/gaia/blob/master/apps/ftu/style/style.css#L1:L3 I'm flagging for a regression window.

Seems cut/copy/paste (CCP) doesn't work while launching FTU from a flash device. The problem should be very similar with Bug 1228151. So, ensuring that "AppTextSelectionDialog" is properly installed while launching FTU should be a fix. However, it is very hard to debug, because the code flow are different between launching FTU from a newly flashed device and that from settings->developer->launch FTU. CCP doesn't work in the former, but it works in the latter. I think making the two code flows being consistent could be a fix. If it's not possible, then we'll have to install "AppTextSelectionDialog" while launching FTU from a flash device.

I just got the info from Bug 1252427. It seems we're removing FTU app.

(In reply to Jeremy Chen [:jeremychen] UTC+8 from comment #8) > I just got the info from Bug 1252427. It seems we're removing FTU app. Yeah, and if this issue is only occuring on the FTU app there's no sense in spending more time on it. Thanks for the diagnosis though we'll need to keep an eye out for similar issues elsewhere. I'll wontfix this one for now though.
