'Cannot find type' error [message #692418]

Hi

I have an error in my grammar and I'm not sure why I'm getting this.
The error is

Cannot find type for 'INT | DOUBLE'

My grammar looks like this:

Condition :
	property=[PropertyDefinition] operator=ComparisonOperation value=(INT | DOUBLE)
;

terminal DOUBLE :
	INT '.' (INT)+
;

The error is thrown within my 'Condition' grammar rule.
Why am I getting this error?
Thanks

Hi,

DOUBLE is an acore::EString
INT an ecore::EInt

this does not fit together. which type should value be of?

Should I thus create a rule that wraps the two types like so?

Condition :
	property=[PropertyDefinition] operator=ComparisonOperation value=ConditionValue
;

ConditionValue :
	DOUBLE | INT
;

terminal DOUBLE :
	INT '.' (INT)+
;

Regards

if you can live with ConditionValue being probably a estring. btw doesn't you double rule hide the int rule and should
be replaced with a datatype rule too?

Hi Christian. I'm not sure what you mean here by 'hiding'. Could you elaborate on this?

Thanks
