Not sure what version of this code you are using but the line is there and passes unit tests.

I have just (30 March 2006) downloaded the 'kitchen sink' distribution 0.2.2 - the line is missing! dojo-0.2.2-kitchen_sink/src/collections/Set.js

... dojo.collections.Set = new function(){

this.union = function(setA, setB){

if (setA.constructor == Array) var setA = new dojo.collections.ArrayList?(setA); if (setB.constructor == Array) var setB = new dojo.collections.ArrayList?(setB);

if (!setA.toArray
!setB.toArray) dojo.raise("Set operations can only be performed on array-based collections.");

var result = new dojo.collections.ArrayList?(setA.toArray()); var e = setB.getIterator(); while (!e.atEnd){

if (!result.contains(e.current)) result.add(e.current);

} return result;


look at the while loop - how is e being iterated?

The 0.2.2 release contained this bug; the trunk does not. If you are using the Set stuff, probably you should grab the nightly or fix it in your local copy.

It *is* fixed in the nightlies, therefore this is closed.
