I have the following two diagrams:

participant "__: Order Fulfilement Clerk__" as pOFC
participant "__: System__" as pS
oOFC -> pS : "1:getOrderNbr() : integer"

"__: Order Fulfilement Clerk__" -> "__: System__" : "1:getOrderNbr() : integer"

The second one works correctly, the first one doesn't compile. What's wrong?

This is a UML 1.x diagram and not a UML 2.x diagram... just wanted to make sure you know that...

in UML 2.x Lifelines are not representing Instances but instead ConnectableElements in a model
