Thank you, this part was already done the right way, the problem occured while importing the pipeling.py in catalyst.<br>
But in the meantime, I realized that it was a missing attribute and a typo that were sort of hiding each other...<br>
Thank you for the fast answer though !<br>

Objet: Re: [Paraview-developers] Adding a Writer plugin to Catalyst in situ<br>
<div><div class="h5"><br>
Hi,<br>
<br>
The key thing is that in the GUI you don't actually create a writer for the<br>
Catalyst pipeline, you need to create a stub for the writer that gets<br>
filled in when you run Catalyst. For example, looking in utilities.xml for<br>
the XMLPImageDataWriter stub:<br>
=================<br>
<SourceProxy name="XMLPImageDataWriter" class="vtkPVNullSource"<br>
label="Parallel Image Data Writer"><br>
<InputProperty name="Input"><br>
<ProxyGroupDomain name="groups"><br>
<Group name="sources" /><br>
<Group name="filters" /><br>
</ProxyGroupDomain><br>
<DataTypeDomain name="input_type" composite_data_supported="0"><br>
<DataType value="vtkImageData" /><br>
</DataTypeDomain><br>
<Documentation><br>
The input.<br>
</Documentation><br>
</InputProperty><br>
<br>
<StringVectorProperty name="FileName"<br>
number_of_elements="1"<br>
default_values="filename_%t.<wbr>pvti"><br>
</StringVectorProperty><br>
<br>
<IntVectorProperty name="WriteFrequency"<br>
number_of_elements="1"<br>
default_values="1"><br>
<IntRangeDomain name="range" min="1" /><br>
</IntVectorProperty><br>
<br>
<IntVectorProperty name="PaddingAmount"<br>
number_of_elements="1"<br>
default_values="0"><br>
<IntRangeDomain name="range" min="0" /><br>
</IntVectorProperty><br>
<br>
<Hints><br>
<!-- TODO: this doesn't work yet --><br>
<PipelineIcon name=":pqComponents/pqSave32.<wbr>png" /><br>
<br>
<!-- This will help us when exporting the script state --><br>
<WriterProxy group="writers" name="XMLPImageDataWriter" /><br>
</Hints><br>
<!-- End of XMLPImageDataWriter --><br>
</SourceProxy><br>
==================<br>
<br>
Note that this is in the insitu_writers_parameters group in that file. Some<br>
subtleties for this, if I remember correctly, are:<br>
<br>
</div></div> - The SourceProxy name attribute may need to be the name of your actual<br>
<span class=""> writer (here it's XMLPImageDataWriter) though I don't think so<br>
</span> - You probably want to include FileName, WriteFrequency and<br>
PaddingAmount properties here.<br>
- In the Hints section the WriterProxy should have the name attribute<br>
<div class="HOEnZb"><div class="h5"> set to the actual writer from your plugin.<br>
<br>
If that doesn't seem to work, I'd suggest looking at coprocessing.py's<br>
RegisterWriter(), WriterParamtersProxy() and WriteData() methods.<br>
<br>
Best,<br>
<br>
Andy<br>
