Put a ** in front of reppro[i], e.g.,

pvs.SetProperties(repr, **reppro[i])

Hm, I now get:
TypeError: SetProperties() argument after ** must be a mapping, not list
Do I have to store the dict of object properties in another dict instead of a 
list?


With a dict of dicts

RuntimeError: This property requires 3 values.

Any ideas what could still be wrong?

Hi Roman,

It turns out ParaView was not designed for this use case because of
certain difficulties discussed here:

https://gitlab.kitware.com/paraview/paraview/issues/17442

In your Python script, you could manually cash all the properties of
the existing representations and restore them after loading the most
recent state file.

The functions

reprs = GetRepresentations()
repr = reprs.values()[0]
props = repr.ListProperties()
GetProperty(repr, props[0])

would be helpful for this.

Dear mailing list members,


It seems that PV (and paraview.simple.LoadState) by default hides already
loaded objects (and resets e.g. their coloring) when another state-file
is
loaded.
Is there a way to load multiple state-files after one another without
hiding
and resetting already existent objects? I.e. a way to concatenate
multiple
state-files and leave their objects in the state as they got loaded (e.g.
colored, hidden/visible)?
I do understand that loading a new state-file will reset the camera, but
not
the rest.
Here's my initial attempt to achieve this with pvpython:
https://github.com/romangrothausmann/ParaView_scripts/blob/90eb4ca8499070bed941d50b89ebea82fd6a9e23/pvsm-multi.py 

Any help or hints are very much appreciated
Roman
