Hi,
Thank you so much in advance for reading this email.
I keep getting the following error message for a rewrite rule which is mentioned below the error message. I do not know what causes it. Could you tell me what I am doing wrong?
Error
Cannot generate grammar because:
(136):C:\Documents and Settings\...\FinalProjectSim.g:103:19:reference to rewrite element name without reference on left of ->.
And the rule is:
servicetypedefinition
:(virtuality)?
'service type'(qualifier)?servicetypename
(formalcontextparameters)?
(virtualityconstraint)?
(specialisation)?end
(validinputsignalset)?
gatedefinition*
entityinservice*
(servicetypebody)?
'endservice type'(qualifier)?servicetypename end
->^(SLIST[$lc.start](virtuality)?
'service type'(qualifier)?servicetypename
(formalcontextparameters)?
(virtualityconstraint)?
(specialisation)?end
(validinputsignalset)?
gatedefinition*
entityinservice*
(servicetypebody)?
'endservice type'name end ^(SLIST[$lc.start](qualifier)?servicetypename))
;
Best wishes,
Al
