[Scip] User constraints checking

Dear SCIP users,
I am implementing my own constraints using the constraint handler as explained in the TSP example of SCIP,The problem I am facing is the feasibility checking with my own constraints, which they don't include problem variables in their scope, but use them to check the feasibility of other given information, In order to see if SCIP respond to my constraints, I set the callback function scip_check returns always infeasible. In solving stage, SCIP detects the infeasibility, but after that it prints solutions that ignore my constraints.
I want to know what is going on inside SCIP ! it detects infeasibility but rather prints infeasible solutions.
Thanks in advance for any explanations.---A. Ouali
