Error in solving nonlinear system for Mechanics.rotational clutch model

Reported by: Bruno Scaglioni Owned by: Willi Braun
Priority: high Milestone: 1.9.0
Component: Backend Version: trunk
Keywords: Cc: Willi Braun

Description

The model:
Modelica.Mechanics.Rotational.Components.OneWayClutch
is initialized by default with stuck=false (boolean) and OMC solves the initial system with stuck=false. At time=0 the variable should change to stuck=true generating an event but it does not.
The error I get on the attached model is:

stdout|info| model terminate | non-linear system solver failed. |
Simulation terminated at time 0.002

Fixing stuck=true, fixed=true as binding equation makes everything work
