Uppaal 5.1.0-beta3 Wrong Number of process locations

Question

I decided to reproduce the following model from the uppaal SMC tutorial

tutorial print.

When I check its syntax using UPPAAL (5.1.0-beta3) I run into the error "Wrong number of process locations" I already isolated the process errors and I noticed that if I remove the clientSpawner from the system, it works.

Error stack trace:

These are my global declarations

// Place global declarations here.

const int CLIENTS = 5;
typedef int[0,CLIENTS-1] clientid_t;
broadcast chan ack[clientid_t], req[clientid_t], term[clientid_t];

clientid_t c;


dynamic Client(int id);

This is the ClientSpawner model

This is the Client Model

This is the Server Model

The only variables missing from global declarations are x and next and they are defined in the local declaration according to its usage

This is the system declaration

// Place template instantiations here.
server = Server();
clientSpawner = ClientSpawner();

// List one or more processes to be composed into a system.
system server, clientSpawner;

Does anyone know how to solve this?

I tried it in uppaal 5.0.0 as well. Same problem

I tried removing clientSpawner from the model and the syntax is correct
