[rules-users] facts custom sort

[Syargey]

But I didn't check when I answered: 
[ERR 101] Line 34:31 no viable alternative at input ')' in query
sortFactsQuery1 in pattern TreeMap

I tried:

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

It doesn't return any results.

But the following query works:

query sortFactsQuery2
	$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: List()
    	from accumulate( $f: Fact() from $tm.values(),
    			collectList( $f ) )
end
