TypeError: _self._toggleState is not a function

[jezsmith]

Hi,
I get this error (TypeError: _self._toggleState is not a function) in FireFox when I click the SelectAll option in the multiselect midget.
as a temporary fix I've changed this:

    // select option tags
    this.element.find('option').filter(function() {
      if(!this.disabled && $.inArray(this.value, values) > -1) {
        _self._toggleState('selected', flag).call(this);
      }
    });

to this:

    // select option tags
    this.element.find('option').filter(function() {
      if(!this.disabled && $.inArray(this.value, values) > -1) {
        //_self._toggleState('selected', flag).call(this);

        if($(this).attr("selected") == "selected") {
            $(this).removeAttr("selected");
        } else {
            $(this).attr("selected", "selected");
        }

      }
    });

I had the same issue. I got around it by declaring _self outside the function. eg

    var _self = this;
    // select option tags
    this.element.find('option').filter(function() {
      if(!this.disabled && $.inArray(this.value, values) > -1) {
        _self._toggleState('selected', flag).call(this);
      }
    });

I had a similar issue. It is interesting to note that the minified version of the script seems to be okay. The problem exists in the non-minified version only. I've followed the logic of the minified version and fixed it similarly to the second comment by TheBenjiManCan.
