Arguments with called rules [message #724266]

Hi,
I'd like to know what sort of parameters I can use when calling a called rule from another rule (only the basic types, or also the types from my source metamodel?).

I have a called rule of this form :

rule createREF (s : A!A1) {
	to
		d:B!B2(
 	              attribute <- s.something
			)
}

which takes as a parameter an instance of A1 type, and a classic matched rule of this form :

rule createDeltaIntRule{
	from
		s:A!A1
	to
		d:B!B1(
			a1<-thisModule.createREF(s)
			)
}

As I said before, I'd like to call createREF, giving to it s (A!A1) as a parameter. Is it possible to do so ?

Thanks for your help

This is possible but in a called rule you have to specify in the "do" code the variable the rule returns.
Here you'd do :

do{
d;
}
