With the new front end in OMC v1.13.0-dev-148-g3532b10, I get:
1] 23:22:10 Symbolic Error Too few equations, under-determined system. The model has 1 equation(s) and 2 variable(s). [2] 23:22:10 Symbolic Warning Variable x does not have any remaining equation to be solved in. The original equations were:
This is really not good. The Modelica Specification, section 9.1, states:
"The connect-equation construct takes two references to connectors..."
If any of the two references in the connect statement is not a connector, a specific error should be issued, it makes no sense to continue further with the back-end.

- Component changed from Frontend to New Instantiation
- Milestone changed from 1.13.0 to 2.0.0
As of 1.13.0, the new front-end produces this error
[1] 14:44:28 Translation Error [A: 4:3-4:15]: x is not a valid connector.
This will be the default behaviour in 2.0.0
