I have the following rule:

Else_Statement:
{Else_Statement}
(hasElse ?= (ELSE else_statement=Statement_List)?)?
;

Terminal ELSE:
'ELSE'
;

The line (hasElse ?= (ELSE else_statement=Statement_List)?)?
gives the following error:

Multiple markers at this line:
- missing ')' at else_statement
- mismatched input ')' expecting ';'

How come this is not allowed?

Hi,

the placement is false. you have to add it before a terminal/datatype rule

Else_Statement:
{Else_Statement}
( (hasElse ?=ELSE else_statement=Statement_List)?)?
;
