Not balanced connectors should generate an error

[Karin Gustafsson]

Create the model:

connector notValid // illegal connector
Real r1;
Real r2;
flow Real r3;
end notValid;

Validate the model

Expected Result: An error, this is an example of illegal modelica from the modelica spec.
Received Results: Warning: Connector .notValid is not balanced: The number of potential variables (2) is not equal to the number of flow variables (1).

[Adrian Pop]

We cannot make it an error as there are connectors
with no flow variables that are used and they would
fail if we make it an error.

For example ThermoSysPro is using this kind of connectors.

Maybe we could make it an error if there are some flows present
in the connector.

Ticket retargeted after milestone closed

[Martin Sjölund]

Milestone moved to 1.12.0 due to 1.11.0 already being released.

[Francesco Casella]

The milestone of this ticket has been reassigned to "Future".

If you think the issue is still valid and relevant for you, please select milestone 1.13.0 for back-end, code generation and run-time issues, or 2.0.0 for front-end issues.

If you are aware that the problem is no longer present, please select the milestone corresponding to the version of OMC you used to check that, and set the status to "worksforme".

In both cases, a short informative comment would be welcome.
