[rules-users] facts custom sort

[Syargey]

I am still wondering why the following query doesn't work:

query sortFactsQuery1
	$tm: TreeMap()
  		from accumulate( $f: Fact(),
                     init( TreeMap map = new TreeMap(); ),
                   action( map.put(factKey($f), $f); ),
                   reverse( map.remove(factKey($f)); ),
                   result( map ) )
    $sortedFacts: Collection() from $tm.values()
end
