BE tries to generate non-existent boolean attributes when disabling tearing

[Andreas Heuermann]

When tearing is disabled, the backend generates code that assumes boolean variables have attributes like min, max or nominal.

Steps to reproduce:
Disabeling tearing with --tearingMethod=noTearing and simulate a model with booleans, like Modelica.Electrical.Analog.Examples.Rectifier

Isn't this fixed with the implementation of minimal tearing?

[Francesco Casella]

Releasing 1.14.0 which is stable and has many improvements w.r.t. 1.13.2. This issue is rescheduled to 1.16.0

[Andreas Heuermann]

Yes, when using --tearingMethod=minimalTearing the model will compile and simulate.

We have to add a message to --tearingMethod=noTearing, that it's deprecated.
