Description

Steps to reproduce:
1.create a Spark:Sort instance under "Declaration" tag without Spark:SortField instances in it. Don't set any property of this sort.
2.create an ArrayCollection data source.
3.set invalid value, like ''(empty string, length = 0, not string of null) to locale style of this sort.
4.set sort property of data source to spark:Sort instance.
5.call refresh() method of ArrayCollection.

Actual Results:
An error dialog popup with title "Undefined locale" popup.

Expected Results:
Sort will works as locale is undefined when set an invalid value of locale.

Workaround (if any):
If set locale value to any string, like "abc", "en-US" after Sort instance created, then set '' value will not cause any error.

NOTE: This bug only happened when set '' to locale of Sort directly after create Sort instance.

Please see detail in attached sample code.
