Problem:
If there is a wrong expression (in this example: an additional bracket) in the MathEvaluator component triggers an error on model starting, stating that it is not possible to start the slider component (input of the MathEvaluator).
Cause:

As it seems, the problematic expression is not handled in the MathEvaluator but propagates through to the slider.
Expected behavior:
The MathEvaluator component should display an error, like "malformed expression"
Example model: (due to file extension limitations, it is renamed to txt) abgabe1.txt
The text was updated successfully, but these errors were encountered:
