hi everyone, i want to make an if/else statement in one of my rules, the idea is if(A) i transform from a to b, and else i transform from a to c.

this is what i did, but i got the following error :Quote:

no viable alternative at input 'if'

rule task {
	from 
		a : modeler_bpmn!task
	to
	    if (a.documentation='middle'){
	    	b : bpmn5!Task
			(
				name <- a.name,
				incomingRTT <- a.incoming,
				outgoingLTT <- a.outgoing
			)
	    }
	    else {
	    	c : bpmn5!FirstTask
			(
				name <- a.name,
			        incomingConnections <- a.incoming,
		    	        outgoingLTT <- a.outgoing
			)
	    }

Thanks you.

The "if" condition normally goes in the "from" part of your rule:

rule task {
from a : modeler_bpmn!task
(
a.documentation='middle'
)
to
b : bpmn5!Task
(
name <- a.name,
incomingRTT <- a.incoming,
outgoingLTT <- a.outgoing
)
}

rule firsttask {
from a : modeler_bpmn!task
(
a.documentation<>'middle'
)
to
c : bpmn5!FirstTask
(
name <- a.name,
incomingConnections <- a.incoming,
outgoingLTT <- a.outgoing
)
}
