The operator "One of" should allow multi-selection

We currently engage the prepopulated easy-select2 allowing only a single choice.

When I try the 'One of' in django 1.6, it selects the regex operator, is this the same problem you're having? You can check this in the console, the selected operator is logged.

I think I meant this as more of an enhancement than a bug. The idea is that "one of" operator should (re-) initialize the select2 widget with the "multiple selection" option. E.g by calling select2 constructor with the multiple option:

input.select2({'data': data, 'multiple': true, 'createSearchChoice': function(term) {
  return { 'id': term, 'text': term }
}});
