The problem is more general.

Create a custom filter using calculator and the data (u,v,w,p) sqrt(u^2+v^2+w^2). Save a custom filter. Now re-open the data but now do not read 'p' array this time (XDMF). Apply custom filter. Calculator will complain p is absent.

Hi,

I've found a bug with the calculator:

create a box
apply calculator filter: array name "a", value "1"
apply calculator again: array name "b", value "2"

now change the input for the second calculator to the box and you get
the following error:

vtkArrayCalculator (0x28b3d40): Invalid array name: a

Even though it doesn't use that array...

Regards,
Paul
