[Paraview] [PV3] Ensight writer plugin problem

[Renato N. Elias]

Following the TiffWriter example, I tried to load the vtkEnsightWriter 
writer as a plugin in PV3. It compiles and load in PV without any 
problem but when I try to save an unstructured mesh using the plugin I 
get the following error message:

ERROR: In ..\..\..\ParaView3_CVS\VTK\Parallel\vtkEnSightWriter.cxx, line 
1154

vtkEnSightWriter (0960B878): Error opening 
.//C:\Kitware\teste.0.00000.geo: Invalid argument


What am I doing wrong? I used a cube source meshed with the "Delaunay 3D 
filter" as test and my xml files were defined with the following parameters:

<!-- GUIEnsightWriter.xml-->
<ParaViewWriters>
  <Writer name="Ensight writer"
          extensions="case"
          file_description="Writes Ensight format">
  </Writer>
</ParaViewWriters>
<!-- end of GUIEnsightWriter.xml-->

<!-- writers.xml (Server Manager side) -->
<ServerManagerConfiguration>
  <ProxyGroup name="writers">
   <WriterProxy name="EnsightWriter"
                class="vtkEnsightWriter"
                label="MyEnsightWriter">
     <InputProperty name="Input" command="SetInputConnection">
        <ProxyGroupDomain name="groups">
          <Group name="sources"/>
          <Group name="filters"/>
        </ProxyGroupDomain>
        <DataTypeDomain name="input_type" composite_data_supported="0">
          <DataType value="vtkUnstructuredGrid"/>
        </DataTypeDomain>
      </InputProperty>
      <Hints>
        <Property name="Input" show="0"/>
        <Property name="FileName" show="0"/>
        <Property name="FileType" show="0"/>
      </Hints>

   </WriterProxy>
  </ProxyGroup>
</ServerManagerConfiguration>

<!-- end of writers.xml -->

# CMakeLists.txt file
FIND_PACKAGE(ParaView REQUIRED)
