Not sure this is needed. Check #220.

No need of any changes,

The problem is with initValueText. Instead of passing an array of key value pair just pass an array of values, that will solve th issue

Example:
If your making multy select of countries with 'code => 'name' pair then the array of items will be
[ 'ind'=>'india', 'qta'=>'qatar', 'cha'=>'chaina', ... ]
So for the select2 widget initValueText you just pass the array of selected values.
if india and chaina are selected then the array should be
['india','chaina']

I think this change is required since in DB keys of the array are stored, not values.
