Warning: Model corruption detected: In the MDL file, object #0 cannot be parented by object #0.
Show older comments
Hello all,
currently I get the following warning below when executing the simulink model via the command !matlab -nosplash -nojvm -r...
However, when executing the simulink model in simulink, the diagnostic viewer never shows the warning messages.
The only thing i did in between there was merging a finished branch into the trunk by hand (copy and paste simulink subsystems), and I adapted the stateflow logic chart. Do you know how to fix this one ? I would be very happy if someone can help me out with this.
Here you can see the warning message:

When doing the merge, did you manually edit the MDL file contents? Instead, you can use Simulink's built-in tools to resolve merge conflicts and avoid model file corruptions:

I would try restoring the default path or, if that doesn't work, doing a reinstall of MATLAB on the affected machine.
