MFString concatenation issue

[OlivierJean]

The following code raises an exception :

file : main.wrl :

DEF SCRIPT Script {
  field MFString myString []

  url "javascript:
    function initialize() {
      var i=0;
      myString[i]='test';
      myString[i]+=' widget';
    }
  "
}

Result :
BUILD FAILED
