fails to flatten model using partial derivatives

[Peter Aronsson]

The frontend fails to flatten model using partial derivative:

model partialDerivativeTest
  Real x,y;
  function surfaceFunction 
     input Real x;
     input Real y;
     output Real z;
   protected  
     parameter Real a=3;
   algorithm
    z := a*x*x;
    annotation(Inline=true);
  end surfaceFunction;
  function surfaceFunction_dx = der(surfaceFunction,x); //Partial derivative
  function surfaceFunction_dy = der(surfaceFunction,y); // Partial derivative

  Real z;
  Real n[3] "normal vector";

equation
   x = 4;
   y = 3;
   z = surfaceFunction(x,y);
   n = {surfaceFunction_dx(x,y),surfaceFunction_dy(x,y),-1};
end partialDerivativeTest;

Gives the error:

Error: [<interactive>:23:4-23:60] Class surfaceFunction_dx not found in scope partialDerivativeTest (looking for a function or record).

Postponed until 1.9.1

[Martin Sjölund]

This ticket was not closed for 1.9.1, which has now been released. It was batch modified for milestone 1.9.2 (but maybe an empty milestone was more appropriate; feel free to change it).

[Martin Sjölund]

Milestone changed to 1.9.3 since 1.9.2 was released.
