[Paraview] Calculator removes cell data

[Fabian, Nathan]

Hi,

I just submitted a bug on this: http://paraview.org/Bug/view.php?id=12944

But I'm wondering if there's a way to work around it.  The problem is that
I'm trying to modify the coordinates insitu using the displacement, but
that ends up deleting the cell data.  Is there any way to merge the cell
data from one data source into the another?

Something like this:

InputData = InputData() #get the input data from coprocessing

Calculator = Calculator () #removes the cell data

Merged = CopyCellDataFromAtoB (InputData, Calculator) #copies the cell
data from InputData, but uses modified mesh from Calculator

Thanks,
Nathan.
