toString() of undefined while filtering on the table

[cggaurav]

.filter('highlight', function() {
return function(text) {
   //previously this
   //if (text.toString().length > 0 && !_.isUndefined(text) && !_.isNull(text)) {
   //now this, to get rid of ~2K + errors on the log!
    if (!_.isUndefined(text) && !_.isNull(text) && text.toString().length > 0) {
      return text.toString().
        replace(/&/g, '&').
        replace(/</g, '&lt;').
        replace(/>/g, '&gt;').
        replace(/\r?\n/g, '<br/>').
        replace(/@start-highlight@/g, '<code class="highlight">').
        replace(/@end-highlight@/g, '</code>')
    }
    return '';
  }
});

These errors also occur when overing over a bar in the bar graph:

@marceldegraaf This should do the trick.

//previously this
   //if (text.toString().length > 0 && !_.isUndefined(text) && !_.isNull(text)) {
   //now this, to get rid of ~2K + errors on the log!
    if (!_.isUndefined(text) && !_.isNull(text) && text.toString().length > 0) {
