_FormSelectWidget value setter does not handle empty arrays correctly

Reported by: fvanham Owned by: fvanham
Priority: undecided Milestone: tbd
Component: Dijit - Form Version: 1.9.3

Trying to clear the selection of a _FormSelectWidget descendant by setting the value to an empty array []. While the value store is updated correctly, these results are not visible in the UI. I believe these lines to be at fault:

var val =, function(opt){
	return opt.value;
if(typeof val == "undefined" !|| typeof val![0] == "undefined"){
} // not fully initialized yet or a failed value lookup

When newValue is the empty array val will be an empty array and typeof val[0] will be undefined, resulting in an early function exit, without updating the UI.

Could be. But I can't check because don't have any descendants of _FormSelectWidget except for Select itself, where value is scalar (rather than an array). So, please attach a test case using the "attach file" button, with instructions including expected results vs. actual results.
