SelectItem.setPickListCriteria() does not work correctly if the passed criteria has an array of allowed values

What steps will reproduce the problem?
1. Run the SelectItemExample (attached)

What is the expected output? What do you see instead?
Study the pick-lists of all the SelectItems
 - "First SelectItem" and "First SelectItem with ShowAll" contain expected checklists
 - While "Second SelectItem" and "SecondItem with ShowAll" do not:
 -- the expected pick-lists are of these SelectItems are "Second Value, Third Value" and "Second Value, Third Value, <separator>, First Value" respectively
 -- the actual pick-lists are "<empty>" and "<separator>, First Value, Second Value, Third Value" respectively

What version of the product are you using? On what operating system?
- Operating system: Windows XP
- Browsers: IE 7 and Firefox 3.6.8(both normal browser and GWT development mode)
- SmartGWT version: 2.1
- GWT version: 2.0.3

Please provide any additional information below.
I've analyzed the code of the SmartClient and found that in the function 
filterClientPickListData() the criterion for a particular field is converted to 
a string irrespectively if it a string or an Array (see the line 1751 of the 
PickList.js attached)
