[Paraview] How to push a value to the ServerManager so it gets pushed down to the Server

[Nehme Bilal]

I see. I already had the same kind of problems but am not able to help much
because there is no enough details in your message. Am not sure if it's a
reader or a filter that you are developing ? are you reading the file on the
client side ? server side ? or both ?

2 potential problems:
- if you are reading the file on both the server and client side, your
plugin will not work when the server is running on different computer
because the file will not be accessible to one of them.

- apply your plugin, save the state, delete all objects and reload the
state, probably something will go wrong.

if you give more details, I'll probably be able to help.
