Hi Pilou,

re:

Almost - it would be good to put a "self-closing" slash on the <moi:Text> and since it will supply the text you don't want any additional text in there.

So you would want it like this:

<moi:CommandButton icon="moi://ui/icons/LineIcon.png" command="line"><moi:Text textid="Line" /></moi:CommandButton>
