External systems in use cases?

Question

How can I make an actor be an external system (rectangle) in a use case? The following is close, but I want the stick-figure (human) CreditAuthorizationService to be the CAS rectangle. Links to the CAS (rectangle) object give syntax errors.

@startuml

left to right direction

skinparam packageStyle rect

actor Client

actor "CreditAuthorizationService" as ac

rectangle CAS {

}

rectangle Système {

  Client -- (CU01:Handle registration)

  (CU01:Handle registration) -- ac

}

Hello,

You can use this:

@startuml
left to right direction
actor Client
rectangle CAS
rectangle Systeme {
  Client -- (CU01:Handle registration)
  (CU01:Handle registration) -- ac
  (CU01:Handle registration) --> CAS : delegate
}

Is this what you are expecting ?

PS: Edited to change "rect" to "rectangle"

Thanks. Here's the precise thing I was looking to do:

@startuml
left to right direction
actor Client
rect "Credit authorization service" as CAS
rectangle Systeme {
  Client -- (CU01:Handle registration)
  (CU01:Handle registration) -- CAS
}

The latest build of PlantUML (on the server) gives a syntax error for this (as well as your example).

---

actually, using "rectangle" as opposed to "rect" works.

---

We have removed "rect" because it was unclear (sorry that it has been was never mentionned : I will update the previous post).
This breaks compatibility, but we think/hope that this change is minor.
Please tell us if it's a real issue for you.

Not an issue for me - I appreciate the quick reply.

Well, we also appreciate user's feedback : it allows us to save time on tests :-)

About tests, I imagine you have already a set of source files you run each release against (relying on users to find broken things is maybe not so good). I realize the language is evolving, and it's probably hard to maintain the tests. But, don't forget some professors have students who need senior projects and this would be a great experience (if ever you wanted to help with a little direction).
