[Paraview-developers] Adding a Writer plugin to Catalyst in situ

[Louka Jacques--Chevallier]

Hello, 
I'm trying to implement a custom asynchronous writer as a plugin for paraview / Catalyst in situ. 

What actually works : 
-The writer works when it's invoked as pure c++
-The xml that describes the writer seems OK as it shows the right extensions when using the "save data" feature in PV (after being imported of course)
-I already added a plugin filter (not writer) to paraview and it works like a charm, so it's about the writer properties in particular
-I'm able to display it as an entry in the in situ Writers menu (using the proxy group : in situ_writer_parameters)
-Exporting a pipeline (in python) using this writer works well, it's shown with the right parameters

What doesn't work : 
-When importing the (previously exported) pipeline.py, it seems that the writer is not found (meanwhile the filter is)

What has been tried : 
-Using the LoadPlugin("mylib.so") in python
-Recompiling unsuccessfully catalyst with the new files for the writer
-Looking for plugins used the same way with in situ, but found nothing...

I don't really know if it is even possible, or if it has been done before, any idea / suggestion will be appreciated ! ^.^

Louka
