Parameter with only start value not accepted

[ceraolo]

A parameter with evaluate=true and only a start value (no binding equation) can be accepted?

Consider model Modelica.Electrical.Machines.Examples.SMPM_NoLoad.
If in the machine we delete the boolean value useDamperCage, the model does not run with NF, while it runs with OF, which issues the following warning:

Parameter smpm.useDamperCage has no value, and is fixed during initialization (fixed=true), using available start value (start=true) as default value.

Replying to ceraolo:

A parameter with evaluate=true and only a start value (no binding equation) can be accepted?

It should, preferably with a warning, see Section 8.6 of the language specification

If a parameter has a modifier for the start -attribute, does not have fixed=false , and neither has a binding equation nor is part of a record having a binding equation, the modifier for the start-attribute can be used to add a parameter binding equation assigning the parameter to that start-modifier. In this case a diagnostic message is recommended in a simulation model
