Dear CPLEX experts,

I'm using the rather new multi-objective functions of CPLEX and I'm wondering, whether CPLEX (in the .NET API) (already) supports the following features:

1. Is there a possibility to treat an user abort only as an abort of the currently optimized objective such that the process continues with the next objective?
2. Is there a callback indicating that one objective hierarchy level is finished such that I could, for example, fix some variables at this point?
3. When I use ParamSets for the objective with the highest priority, I get an AccessViolationException after the solver starts the optimization. Am I making something wrong or may there be a bug?

Looking forward for your answers!

Best regards,

Anka
