Bidimensional array returns extra comma when command Type is used

Imagine a bidimensional array arrTOT[2][2].
If you use a command like:

Type| id=textarea | ${arrTOT}

the result is going to be: x,y,z,w.
There’s an extra comma coming out. The bug is that the uses comma to separate columns and rows.
It would be easier if every new line was marked by a";" or the TYPE result comes out like a csv file:


Here is a workaround I found:

var jorge = ${LANE};
var texto = “”;
for(var i = 0; i < jorge.length; i++) {
texto += jorge[i].join(“,”) + “\n”;
return texto;
