[Paraview-developers] JavaScript API: change representation

[Sebastien Jourdain]

Hi Dave,

Are you using one of the existing client side or are you trying to build
your own UI?
Normally you should get the proxy id from the reply of the data that you
loaded.

But you might be able to get more information on that API by looking at the
PipelineManager widget JavaScript code and see how it handle representation
change.

Or check the server side src/Web/Python/protocol.py to see what is done
with the message.

Seb
