Incorrect warning regarding missing 'inner' declaration.

[dhedberg]

Consider the following definitions:

package A

  model C1
    extends CBase;
    model S1
      extends SBase;
    end S1;

    S1 s1;
  end C1;

  partial model CBase
    inner Real V=1;
  end CBase;

  partial model SBase
    outer Real V;
  end SBase;

end A;

Checking the package the results in the following warning:
Warning: No corresponding 'inner' declaration found for component V declared as 'outer '. Please declare an 'inner' component with the same name in the top scope. Continuing flattening by only considering the 'outer' component declaration.

This warning should not be there, the matching inner declaration of V in SBase, is found in CBase which is inherited by C1.

This bug is a major bug as all SBML models when being translated to Modelica in MathModelica get this structure and hence this warning.

MathCore note: This ticket corresponds to ticket 2958 in MathModelica trac.

Issue verified.

Somewhere in the instantiation instVar is called with no prefix
Prefix.NOPRE while instantiating component s1 with type S1, so
I end up instantiating outer V with no prefix (top scope), which gives
this warning. Investigating it now.

[adrpo]

Oh, the horror. The problem is that it tries to instantiate SBase as a class extending
basic types with Prefix.NOPRE() (top level) and it fails, but not before printing those
error messages. Getting rid of these error messages is not that easy as you still want
to print the errors regarding classes extending basic types.

At least now I know what the problem is, but I'll have to investigate more on how to fix it.

[adrpo]

Fixed, see SCM Commits for more info.

[dhedberg]

The problem is still there (to some extent). If I call getErrorString() after the a call to checkModel(A) I still get the same warning.

Warning: No corresponding 'inner' declaration found for component V declared as 'outer '. Please declare an 'inner' component with the same name in the top scope. Continuing flattening by only considering the 'outer' component declaration.

What is checkModel(A) supposed to do?? A is a package\\
If I run this script on OpenModelica:

loadFile("InnerOuter.mo"); getErrorString();
instantiateModel(A.C1); getErrorString();
checkModel(A.C1); getErrorString();
checkModel(A); getErrorString();

I get this:

adrpo@kafka ~/dev/OpenModelica/build/bin
$ ./omc InnerOuter.mos
true
""
"class A.C1
  Real V = 1.0;
end A.C1;
"
""
"Check of A.C1 completed successfully.


Class A.C1 has 1 equation(s) and 1 variable(s).
1 of these are trivial equation(s).
"
""
"Check of A completed successfully.


Class A has 0 equation(s) and 0 variable(s).
0 of these are trivial equation(s).
"
""

If i run this (checking of all models within package A)

loadFile("InnerOuter.mo"); getErrorString();
checkAllModelsRecursive(A); getErrorString();

I get this:

adrpo@kafka ~/dev/OpenModelica/build/bin
$ ./omc InnerOuter.mos

BUT the warnings are *perfectly* normal in this case as we are instantiating
the classes without a context in which inner is present!
