[Osi] setting problem's name using OsiCbcSolverInterface

[Hacène Ouzia]

Hi,

What is the right way to set the problem's name using  
OsiCbcSolverInterface. I tried to set it as below, but  it doesn't work.

Thanks for help.

Cheers,
Hacene.

...
OsiCbcSolverInterface OSI_SOLVER;
....
  OSI_SOLVER.loadProblem(MATRIX,COL_LB,COL_UB,OBJECTIVE,ROW_LB,ROW_UB);
		
  OSI_SOLVER.setIntParam(OsiNameDiscipline,2);
		
  std::string PROBNAME("MKnapsack");										
  OSI_SOLVER.setStrParam(OsiProbName, PROBNAME);

...
....

cat MKnapsack.mps
NAME          BLANK
ROWS
  N  OBJROW
  L  row-1
  L  row-2
  L  row-3
.....
.....
