Utkarsh Apologies, I didn’t get chance to try this properly until now, When I call this
vtkClientServerStream stream; stream << vtkClientServerStream::Invoke << VTKOBJECT(proxy) << "SetSelectedGIds" << numValues; stream.InsertArray(data, numValues); stream << vtkClientServerStream::End; Inside my client server generated wrapper is this code if (!strcmp("SetSelectedGIds",method) && msg.GetNumberOfArguments(0) == 4) { int temp0; vtkClientServerStreamDataArg<int > temp1(msg, 0, 3); if(msg.GetArgument(0, 2, &temp0) && temp1) { op->SetSelectedGIds(temp0,temp1); return 1; } } Which is generated from void SetSelectedGIds(int N, const int *Ids); But when I step though the received message, the msg parameter only has GetNumberOfArguments == 3 If I adjust the client server wrapped code to accept 3 args instead of 4, then the numValues looks correct, but the pointer is wrong. Q1 : why does the message only have 3 params when the wrapper wants 4 Q2 : What should I change? I guess that something else needs to be inserted into the stream, but after having a poke round, I couldn’t guess what.
