Thanks a lot, David. Both you and Karl nailed my problem. I was not aware of the XML aspect at all by following http://www.cmake.org/Wiki/ParaView/Plugin_HowTo#Adding_a_Reader http://www.kitware.com/products/html/WritingAParaViewReaderPlug-in.html which all stopped at exposing WHOLE_EXTENT(), SPACING(), and ORIGIN(). Maybe my experience can be crafted into an updated reader plugin tutorial? Best, x

The AVS UCD entry in filters.xml has the following, the first is an information_only (ie readback) property that tells ParaView what the available arrays are, the sencond is a normal (ie write) property that tells ParaView how to tell which arrays to enable. With these, ParaVIew should create the selection widget on the Properties tab and then be able to call those Set methods you added to the reader. <StringVectorProperty name="CellArrayInfo" information_only="1"> <ArraySelectionInformationHelper attribute_name="Cell"/> </StringVectorProperty> <StringVectorProperty name="CellArrayStatus" command="SetCellArrayStatus" number_of_elements="2" repeat_command="1" number_of_elements_per_command="2" element_types="2 0" information_property="CellArrayInfo" label="Cell Arrays"> <ArraySelectionDomain name="array_list"> <RequiredProperties> <Property name="CellArrayInfo" function="ArrayList"/> </RequiredProperties> </ArraySelectionDomain> <Documentation> This property contains a list of the cell-centered arrays to read. </Documentation> </StringVectorProperty> David E DeMarle Kitware, Inc.
