When the role options are filtered by the
array_uniquefunction their indices are preseverd. This leads to faulty serialization while the options are transmitted to the client. The Ext.Js expects an array to populate the multiselect but due to this an object is serialized and returned.This PR ensures that the array keys are in numerical order and start at 0 (list instead of associative).
