725919 - Visual cursor position is different from the actual one on Etherpad

Status: RESOLVED INCOMPLETE

(Firefox for Android Graveyard :: Keyboards and IME, defect, P5)

Description

[Alex Pakhotin (:alexp)]

While working on bug 719121 I found the cursor position we receive from Gecko using NS_QUERY_SELECTED_TEXT event is sometimes different from the visual position on Etherpad. This causes some weird things to happen when a new text is entered in a wrong position or a wrong character is deleted.
This usually happens around end/beginning of a line (the '\n' character).

NS_QUERY_SELECTED_TEXT is using DOM selected range for getting the selection range. You should confirm if the selected range is correct, first.

Do we have an example pad-page hyperlink?

It would be really nice to have some references allowing als normal users ot dind out whether his observations are this bug or something different.

For example <https://etherpad.mozilla.org/OhUGdNHs7j> with Android FF 38.0.5 on Samsung GT-P3110 with Android 4.1.2:
0. Open above mentioned Mozpad page
1. Below heading "Build-properties:" click before first character "a" of line
   "application=suite ..." so that caret flashes left from "a"
2. Type "a"
   Expected: "a" inserted as first character of text line
   Actual: "a" inserted as last character of line above behind "?"

Is that the problem we are talking about here?

Strike:     "allowing als normal users ot dind"
Replace by: "allowing a normal user to find"

Could anyone still reproduce this? comment #3 is gone away, so I don't know whether this issue still occurs.

If it wouldn't be reproducible with the latest beta, I think that we don't need to take a time for it.
