Multi-level redeclare

[hubert.thieriot@…]

Hi,

The behavior of OM is not the one user could expect on the following case.

MyModel1 and MyModel2 results seem correct.

But MyModel3 still gives 1.0 as result while, to me, it should give 2.0.

Best regards,

Hubert

equation

result = model1.result;

end MyModel3;

Test2 is probably a better illustration since in that case, Model3 building fails (I removed default package version in component).

See log2.txt.

Redeclare is the target of the new instantiation. I will not be fixed in 1.9.0.

With today's nightly build, the result is correct with both old and new front end.
