There is a LL(*) grammar from here: www.antlr.org/wiki/display/~admin/LL%28*%29+grammar+analysis
Model: (elem=rules_s); rules_s : rule_e 'X' | rule_e 'Y' ; rule_e : 'L' rule_e 'R' | 'I' ; Xtext posts this error message when generating workflow: "rule ruleassignment_expression has non-LL(*) decision due to recursive rule invocations reachable from alts 1,2" What is the reason? Xtext does not parse all LL(*) grammars, does it?
