Variable names in callback (Java API)
I construct a cut in a preintsol callback using variables from the model containing the callback. When constructing the model, I give the variables names (using withName(...)) and store them in a vec...
The problem is that the names in the original space are not accessible while the model is in presolved space. They are stored internally but no longer accessible from any API.
