[flexcoders] Re: Result to ArrayCollection - somtimes node is single, sometimes it's an array

[greenfishinwater]

This works for me:

if (event.result.price_sets.price_set is ArrayCollection) {
  arr = event.result.price_sets.price_set.source;
} else {
  arr = [event.result.price_sets.price_set];
}

arrCol = new ArrayCollection(arr);

[leds usop]

If the result format is set to object... or not set at
all (default is object), the result will be wrapped by
an ObjectProxy if there's a single node. Hence
Andrew's solution should do the trick.  However, in my
case, to ensure that I can indeed use it as an array i
do:

ArrayUtil.toArray(event.result.SomeNode);

then assign that to arr if its a valid array (or throw
an error if not). then set arr as the source of the
new arraycollection.
