Comment 2 for bug 821586

Some additional information:

Onboard not only shows the wrong layout, but typing with it also sends the characters shown by the wrong layout.

After typing on a hardware keyboard, Onboard shows the correct layout, but clicking on Onboard does not sent the key of the correct layout, but the key of the wrong layout appearing immediately after clicking the key.

Moreover, the indicator to switch layout does not work either, when Onboard shows the wrong layout. However, when Onboard shows the correct layout (after typing a key on the hardware keyboard), Onboard follows the layout changes done with the indicator icon.
