[Mark Proctor (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBRULES-2376?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12523731#action_12523731 ] 

Mark Proctor commented on JBRULES-2376:
---------------------------------------

end is currently a "hard" keyword for the antlr parser, so cannot be used as a field name.

> Consider the following: 
> declare Foo
>    end : String
> end
> rule "foo" dialect "java"
> when
> then
>    foo = new Foo()
>    e = foo.end()
> end
> The compiler fails with the following error:  [xx,yy]: [ERR 102] Line xx:yy mismatched input '('  
> If the rule is changed to (ie, remove the parens on the 'end')
> rule "foo" dialect "java"
> when
> then
>    foo = new Foo()
>    e = foo.end
> end
> The compiler error is: [0,-1]: [ERR 101] Line 0:-1 no viable alternative at input '<eof>'
