Since about snapshot #1228 I get for val x0 = rs1.members.filter[s|s.state == 0].size Invalid number of arguments. The method filter(Iterable, Function1<? super T, Boolean>) is not applicable for the arguments (Set) and 2018-03-17 21:40:45.399 [WARN ] [el.core.internal.ModelRepositoryImpl] - …

Jusst a guess: Add spaces between [ and ] val x0 = rs1.members.filter[ s | s.state == 0 ].size

Rule filter
