Hey,

the last days I tried to get around with with ANTLR, got in touch with a lot of tutorials etc.
Now I've started a own project, but get an anoying error:

			

			[fatal] rule functionBlock has non-LL(*) decision due to recursive rule invocations reachable from alts 1,2.  Resolve by left-factoring or using syntactic predicates or using backtrack=true option.
			

			|---> (field)*
		

I don't know how to deal with it. I tracked it down to 2 rules
(my guess: antlr doesn't know which one it should choose)

			

			

			functionBlock //ERROR
			

			: LBRACE
			

			(field)*
			

			(statement)*
			

			RBRACE
			

			;
			

			

			returnStatement
			

			: RETURN expression? SEMI
			

			;
			

			

			struct
			

			: STRUCT IDENT structBlock SEMI
			

			;
			

			

			structBlock
			

			: LBRACE (field)+ RBRACE
			

			;
			

			

			field
			

			: CONST type (arrayDecl)* IDENT EQ expression
			

			SEMI
			

			| type IDENT (EQ expression)? SEMI
			

			| type (arrayDecl)+ IDENT SEMI
			

			;
			

			

			//field and assignmentStatement are the problems, I think.
			

			assignmentStatement
			

			: IDENT assignSymbol expression SEMI
			

			| IDENT (arrayDecl)+ assignSymbol expression SEMI
			

			;
			

			

			type
			

			: primitiveType
			

			| IDENT
			

			;
			

		

So I noticed it has to do with the field and assignmentStatement rules...
could someone tell me what I'm doing totally wrong?
thanks for help :)
