The form is always $dirty as soon as it loads if it contains the ui-select.

This watcher makes ngModel dirty because it's always called:

@dmytroyarmak: Good catch. But if you disable this line, it does never change to dirty (even when you change values). I only can reproduce this issue when mode "multiple" is used.

Anyone found a solution for this?

Might be a bit gross but this is how I'm working around it atm...
https://github.com/angular-ui/ui-select/blob/master/src/select.js#L794-L809

if ($select.multiple){
      scope.$watchCollection(function(){ return ngModel.$modelValue; }, function(newValue, oldValue) {
        if (oldValue != newValue)
          ngModel.$modelValue = null; //Force scope model value and ngModel value to be out of sync to re-run formatters
      });
      $select.firstPass = true; // <-- added this
      scope.$watchCollection('$select.selected', function() {
        if (!$select.firstPass) // <-- added this
          ngModel.$setViewValue(Date.now()); //Set timestamp as a unique string to force changes
        else                    // <-- added this    
          $select.firstPass = false; // <-- added this
      });
      focusser.prop('disabled', true); //Focusser isn't needed if multiple
    }else{
      scope.$watch('$select.selected', function(newValue) {
        if (ngModel.$viewValue !== newValue) {
          ngModel.$setViewValue(newValue);
        }
      });
    }

I'm having this issue as well in multiple mode

[pandamouse]

If it's acceptable then I should try and put it in as a fix?

This was fixed via #509. This issue should be closed.
