<p>Set does not guarantee the order of elements. It's an implementation detail. If you only need to remove duplicates, have a look at #withoutDuplicates.</p>

<div class="PlainText">Hi Folks.<br>
<br>
<br>
If I have an OrderedCollection and convert it to Set via asSet, am I<br>
guaranteed that the resulting Set contains elements in the same order as the<br>
OrderedCollection?<br>
<br>
Here is my problem. <br>
<br>
I have an OrderedCollection with the same element in it twice. By same<br>
element, I mean they are the same object.<br>
<br>
*an OrderedCollection(<br>
A<br>
NESTED TABLE CELL<br>
<br>
B <br>
A<br>
NESTED TABLE CELL<br>
<br>
)<br>
*<br>
<br>
Above, the first and third elements are the same XMLElement. I now this<br>
because if I inspect them and then change one, the other changes.<br>
<br>
if I run asSet on the OrderedCollection, I get what I need:<br>
<br>
*a Set( A<br>
NESTED TABLE CELL<br>
<br>
B)*<br>
<br>
<br>
In that conversion, can I rely on that Ordering being preserved?<br>
<br>
If not, a pointer to the correct select/reject/inject/detect...sort of thing<br>
would be much appreciated.<br>
<br>
cheers.<br>
