VTK: Unable to define two sets of CELL_DATA

I can define only one of the two sets of CELL_DATA without error. When I specify the second one, I get and error"Unsupported cell attribute type: cell_data"
Mesh.vtk (260.0 KB)
It is an unstructured mesh (finite element), and am trying to assign first integer values to a cell, and then a float one

Thanks

Silly error, I should not have defined twice the CELL_DATA anchor.
I sure wish that someone will write a truly comprehensive manual for VTK (but then agian, maybe that is how it is meant to be)
