The Grouping object applied to the source data.
Setting this property does not automatically refresh the view;
therefore, you must call the refresh() method
after setting this property.
Note: The Flex implementations of IGroupingCollection retrieve all items from a remote location before executing grouping.

If the refresh is performed asynchronously,
cancels the refresh operation and stops the building of the groups.
This method only cancels the refresh
if it is initiated by a call to the refresh() method
with an argument of true, corresponding to an asynchronous refresh.

Applies the grouping to the view.
The IGroupingCollection does not detect changes to a group
automatically, so you must call the refresh()
method to update the view after setting the group property.
The refresh() method can be applied asynchronously
by calling refresh(true).
When refresh() is called synchronously,
a client should wait for a CollectionEvent event
with the value of the kind property set
to CollectionEventKind.REFRESH
to ensure that the refresh() method completed.
Parameters
async:Boolean (default = false)true, defines the refresh to be asynchronous.
By default it is false denoting synchronous refresh.
|
Boolean — true if the refresh() method completed,
and false if the refresh is incomplete,
which can mean that items are still pending.
