Base model parameters disappear from GUI when edit Extended model

[Simone Bosotti <simone1.bosotti@…>]

Consider to work on a model, called "Container" using diagram view in OMEdit. This model contains a model "ExtendedModel" that extends a "BaseModel".
If I modify the extended model and save, when I go back to the container model the parameters contained in the base class are no more visible in the parameters window.
They appear again only unloading and reloading again the package.

Procedure:
1) load the attached test.mo package
2) open "Container" and check that both "a" and "b" input fields are present
3) open "ExtendedModel" and change the equation "c = a+b" into "c = a*b"
4) go back to "Container" and open the parameter window for extendedModel
5) "a" input field does not appear anymore

Thanks @Simone!

@adeas31, there are probably other similar such cases, due to cached information not being properly updated.
