Envornment

• E7 + SR1 wk41

Source code

import QtQuick 1.1

TextEdit {
    width: 400; height: 400;
    color: "white"
    text: "World\n"
}

Steps to reproduce

1. Activate Predictive Text (Settings -> Phone -> Language -> Predictive Text -> check Letter keyboard)
2. Open the sample application (SandBoxQML.sis)
3. Go to landscapemode, opening the keyboard slide
4. Put cursor before the word "World"
5. Type "gg" using the hardware keyboard
6. Press down arrow to show the candidate list
7. Select "gg" either by tapping, pressing space or enter key

Actual result

• The text becomes "ThWorth" (video attached: 2011018_006.mp4)

Expected result

• The text becomes "bbWorld"

NOTE: "Th" inserted instead of "bb" is a bug that needs to be fixed in Symbian's text input. On this report, please investigate why the last 2 letters "ld" get replaced by "th"
