Description Moritz Eysholdt

the type of 

---
def unassignedCalledTokenRules() {
  grammar.containedRuleCalls.filter(e | !e.isAssigned() && !e.isEObjectRuleCall()).map(e | e.rule)
}
---

is resolved to Iterable<void>. It should be Iterable<AbstractRule>.

containedRuleCalls(), isAssigned() and isEObjectRuleCall() are imported via
import static extension org.eclipse.xtext.GrammarUtil.*

The type of e in the closure passed to the map cannot be resolved during linking (cannot resovlve reference to JvmIdentibiable element 'rule'), but is resolved later (hover shows correct type).
