1244	Can't find matching inner	Peter Aronsson	Peter Aronsson	"After looking more into this example I have actually managed to simplify it and triggered the problem (thus reopening the issue). 

Consider the following package:
{{{
package MyPackage
  package Effects
    package Internal
      model ParticleEffect2
        outer MyPackage.UpdateVisualization myEnvironment1;
      end ParticleEffect2;

    end Internal;

    model ParticleEffect1
      MyPackage.Effects.Internal.ParticleEffect2 particleEffect2;
    end ParticleEffect1;

  end Effects;

  package Examples
    package Effects
      model ParticleEffect
        MyPackage.Effects.ParticleEffect1 particleEffect1;
        inner MyPackage.UpdateVisualization updateVisualization;
      end ParticleEffect;

    end Effects;

  end Examples;

  model UpdateVisualization
  end UpdateVisualization;

end MyPackage;
}}}
Checking of MyPackage.Examples.Effects.ParticleEffect works fine:
{{{
Check of MyPackage.Examples.Effects.ParticleEffect completed successfully.
Class MyPackage.Examples.Effects.ParticleEffect has 0 equation(s) and 0 variable(s).
0 of these are trivial equation(s).
}}}
However, if UpdateVisualization is not an empty class:
{{{
  model UpdateVisualization
    parameter Real x=1;
    parameter Real y=3;
  end UpdateVisualization;
}}}
Then we fail to find the matching inner:
{{{

This is a simplified version of a typical model from DLRs Visualization library."	defect	closed	critical	Red October			worksforme		Peter Aronsson Adrian Pop
