Replaceable package behaves different when encapsulated in a package

[perob88]

Consider the following set of definitions. It is somewhat similar to the media library building blocks.

partial package partialStuff

constant Integer nz = 1;

end partialStuff;

package simpleStuff

extends testPackage.partialStuff(nz = 2);

end simpleStuff;

class modelComponent

replaceable package theStuff = testPackage.partialStuff;
Real compVar;

equation

compVar = theStuff.nz;

end modelComponent;

Now let's instatiate the following model

model myModel

package theStuff = simpleStuff;
modelComponent comp(redeclare package theStuff = theStuff);

end myModel;

This yields: OMC-ERROR: "Error: Class myModel.theStuff not found in scope modelComponent.theStuff.

Encapsulating everything inside another package:
package testPackage
...
...
...
...
end testPackage

followed by instantiateModel(testPackage.myModel) gives correct results.

A third variant where the only difference is another level of instantiation gives the wrong results but no compiler complaints...:

class myModel

replaceable package theStuff = partialStuff;
modelComponent comp(redeclare package theStuff = theStuff);

end myModel;

model myModel2

myModel modelInst(redeclare package theStuff = simpleStuff);

end myModel2;

instantiateModel(myModel2)
..
..
equation

modelInst.comp.compVar = 1.0;

Here the problem is that compVar should be 2.0 instead of 1.0
