Hi all,

So, I’m trying to modify the background of my view. This is part of my python code:

```
from paraview import simple, servermanager 
..
..
try:
  view = simple.FindView('RenderView1')
  simple.Render(view)
  view.Background = self.background
except AttributeError:
  traceback.print_exc()

```

and it prints:  
Attribute error: ‘NoneType’ Object has no attribute ‘Background’

Any thoughts on this?

I am compiling against paraview web 3.2.2.

I appreciate your help.

Looks like there’s no view of the name `RenderView1` in your scene, that’s why `view` is `None`. Try calling `GetViews` to get a list of views created. If not empty, then you may be just using a incorrect name.

Yes! Silly me.  
Actually I posted a simplified version of the code. It was looking for a non existent view.

Thanks.
