[Paraview] unexpected behavior w/ "Load State" command

[Moreland, Kenneth]

Geoff,

I just added a feature request for the color loss issue.  It's not specifically wrong, but I can see how it can be annoying.

  http://www.paraview.org/Bug/view.php?id=8081

As with respect to the "large" disk, this is caused simply by the fact that the disk is larger than the cone.  ParaView resizes the window whenever an object is made visible when no other objects are made visible.  When you loaded the new state, the smaller cone was made visible first, which caused the window to resize to its bounds.  When the disk is made visible, it looks larger because the camera is zoomed in.  It would be really annoying to have the camera reset every time you made an object visible.  (Trust me, we tried it.)

Geoff,

When one sets up display properties from the Display tab, these
properties apply to the way that data is shown in the current active
view. When state file is loaded, all current views are destroyed and new
views, as specified in the state file, are created and only those
objects that were visible in the state file remain visible. Since new
views are created (and old ones destroyed) all the changes you made to
the Display tab are lost.

Actually, there's even talk of deleting all existing objects before
loading state. If that's done then you'd even loose the disc source.
