Hi,
currently I am adapting some of my software to work with OF 4.1. The new post processing functionality is giving me a hard time though.
If I for example run the motorBike tutorial and create a total pressure field using:

mpirun -np 6 postProcess -func 'totalPressureIncompressible(U,p)' -parallel -latestTime

I get a new field in the 500 folder called "total(p)".
If I now modify the cuttingPlane stuff to this to include the total pressure:

cuttingPlane
{
    type            surfaces;
    libs ("libsampling.so");
    writeControl    writeTime;

    surfaceFormat   vtk;
    fields          ( p U total(p));

    interpolationScheme cellPoint;

...

I will later not get the expected cutting planes but this message:

--> FOAM Warning : 
    From function Foam::label Foam::sampledSurfaces::classifyFields()
    in file sampledSurface/sampledSurfaces/sampledSurfacesGrouping.C at line 75
    Cannot find registered field matching total(p)

In older OF versions I simply renamed the field with brackets to something new and it worked. If I do that now it does not help. The funny thing is that in 4.1 using total(p) as a field to create an isosurface does work.
So as I prefer not to change anything in the OF code I am wondering what I can do. I tried casting the brackets with all kinds of tricks but it never helped.

Does anyone have an idea?
