[Paraview] xdmf not recognizing tuples?

[Peter Brady]

Hello all,

I'm trying to visualize some hdf5 data using the xdmf reader and I'm
encountering some issues.  My grid loads fine but when I try to import
a variable (ie. 'U') I get the error:
   Cell array U with 1 components, has only 0 tuples but there are 1024 cells

Below is my xmf file:
<?xml version="1.0" ?>
<!DOCTYPE Xdmf SYSTEM "Xdmf.dtd" []>
<Xdmf>
  <Domain>
    <Grid Name="Rectilinear" GridType="Uniform">
      <Topology TopologyType="3DSMesh" Dimensions="1 65 17" >
      </Topology>
      <Geometry GeometryType="X_Y">
	<DataItem DataType="Float" Precision="8" Dimensions="1 65 17" Format="HDF">
	  grid.h5:/xcorr2
	</DataItem>
	<DataItem DataType="Float" Precision="8" Dimensions="1 65 17" Format="HDF">
	  grid.h5:/ycorr2
	</DataItem>
      </Geometry>
      <Attribute Name="U" Type="Scalar" Center="Cell">
	<DataItem DataType="Float" Precision="8" Dimensions="1 64 16" Format="HDF">
	  data.init:/U
	</DataItem>
      </Attribute>
    </Grid>
  </Domain>
</Xdmf>
running h5ls on my data.init file yields:
h5ls data.init
T                        Dataset {1, 64, 16}
U                        Dataset {1, 64, 16}
V                        Dataset {1, 64, 16}
VOF                      Dataset {1, 64, 16}
W                        Dataset {1, 64, 16}
dims                     Dataset {4}
names                    Dataset {5}
time                     Dataset {2}

So 'U' has the dimensions 1x16x64 = 1024 cells.  Am I missing something?

Thanks for any help.
Peter.
