2346	replaceable component with modifiers cause instantiation to fail	Peter Aronsson	somebody	"Consider the following model, based on an example in the Belts (commercial) library:

{{{
package B 
  connector Flange_b 
    Real phi; 
    flow Real tau;
  end  Flange_b;

  partial model Base 
   parameter Real pD;
   Flange_b f_b;
  end Base;

  model BaseImpl 
    parameter Real pD;
    Real y;
    Flange_b f_b;
  end BaseImpl;

  model WA 
    parameter Real diam = 1;
    replaceable Base cm(pD = diam);
    Real x = cm.f_b.phi;
  end WA;
 
end B;
model Test 
  B.WA w(redeclare B.BaseImpl cm);
end Test;
}}}
This results in the error message: 

{{{
 Error: Variable cm.f_b.phi not found in scope B.WA
}}}
Now, if you change the declaration in WA to:

{{{
replaceable Base cm(pD = /*diam*/ 1 );
}}}
it works fine.

I've tested to check this model in Dymola and it works fine.

This is a blocker for supporing the Belts library.
