[Paraview] How to insert annotate time info into catalyst?

Dear Andy Bauer,

For the color map issue, I think ParaView 5.4.1 resolved it. But, I 
could not figure out annotate time filter issue. may be it is just 
simple problem but I am not sure. Coprocess routine is as follows and 
python script is attached.

It would be appreciated if you make some advice.


void CoProcess(Foam::fvMesh& mesh, Foam::Time& runTime)
{
        vtkNew<vtkCPDataDescription> dataDescription;
        dataDescription->AddInput("input");
        const double time = runTime.value();
        const unsigned int timeStep = runTime.timeIndex();
        dataDescription->SetTimeData(time, timeStep);

        if (runTime.end())
        {
            // assume that we want to all the pipelines to execute
            // if it is the last time step
            dataDescription->ForceOutputOn();
        }
        if 
(Processor->RequestDataDescription(dataDescription.GetPointer()) != 0)
        {
            Foam::polyMesh::readUpdateState meshState = mesh.readUpdate();

            if(meshState != Foam::polyMesh::UNCHANGED)
            {
                // mesh moved? or mesh topology changed?
                BuildVTKGrid(mesh, true);
            }
            UpdateVTKAttributes(mesh);
dataDescription->GetInputDescriptionByName("input")->
                SetGrid(multiBlockDataSet);
            Processor->CoProcess(dataDescription.GetPointer());
        }
}

Regards.
