Summary0012929: Calculator gives incorrect results for multiblock datasets
DescriptionThe calculator gives incorrect results for multiblock unless the variables have the same index internally. This can be reproduced with the steps below:

1. Create a python source that outputs vtkUnstructuredGrid with the following script:
def add_scalar(ds, val):
                arr = vtk.vtkDoubleArray()
                arr.SetName("Scalar"+str(val))
                arr.SetNumberOfComponents(1)
                arr.SetNumberOfTuples(8)
                for i in range(8):
                                arr.SetTuple1(i, float(val))
                output.GetPointData().AddArray(arr)

output = self.GetOutput()
npts = 8
pts = vtk.vtkPoints()
pts.InsertNextPoint(-3.0, -1.0, -1.0)
pts.InsertNextPoint(-1.0, -1.0, -1.0)
pts.InsertNextPoint(-1.0, 1.0, -1.0)
pts.InsertNextPoint(-3.0, 1.0, -1.0)
pts.InsertNextPoint(-3.0, -1.0, 1.0)
pts.InsertNextPoint(-1.0, -1.0, 1.0)
pts.InsertNextPoint(-1.0, 1.0, 1.0)
pts.InsertNextPoint(-3.0, 1.0, 1.0)
output.SetPoints(pts)
output.Allocate(1,1)
ids = vtk.vtkIdList()
for i in range(npts):
    ids.InsertId(i,i)
add_scalar(output, 1)
add_scalar(output, 2)
output.InsertNextCell(vtk.VTK_HEXAHEDRON, ids)
2. Create a second python source that outputs vtkUnstructuredGrid with the following script (notice the change in order when adding the scalars):
def add_scalar(ds, val):
                arr = vtk.vtkDoubleArray()
                arr.SetName("Scalar"+str(val))
                arr.SetNumberOfComponents(1)
                arr.SetNumberOfTuples(8)
                for i in range(8):
                                arr.SetTuple1(i, float(val))
                output.GetPointData().AddArray(arr)

output = self.GetOutput()
npts = 8
pts = vtk.vtkPoints()
pts.InsertNextPoint(-3.0, -1.0, -1.0)
pts.InsertNextPoint(-1.0, -1.0, -1.0)
pts.InsertNextPoint(-1.0, 1.0, -1.0)
pts.InsertNextPoint(-3.0, 1.0, -1.0)
pts.InsertNextPoint(-3.0, -1.0, 1.0)
pts.InsertNextPoint(-1.0, -1.0, 1.0)
pts.InsertNextPoint(-1.0, 1.0, 1.0)
pts.InsertNextPoint(-3.0, 1.0, 1.0)
output.SetPoints(pts)
output.Allocate(1,1)
ids = vtk.vtkIdList()
for i in range(npts):
    ids.InsertId(i,i)
add_scalar(output, 2)
add_scalar(output, 1)
output.InsertNextCell(vtk.VTK_HEXAHEDRON, ids)
3. Group the two python sources together
4. Use the Calculator filter to pass through Scalar1
