Summary0014283: Color editor doesn't update - CAM data
DescriptionHaven't been able to replicate this with any other data. Sorry. Utkarsh has all of the data for this bug.

Linux, master, remote server (8 servers).
Read in CAM NetCDF (Unstructured) reader.
Use "Connectivity File Name"
Unclick Cell Layer Right. Click Single Level.
Color by TMQ.

Open the Color Editor.
Make sure auto apply is OFF.
Select Enable opacity mapping for surfaces.

Now, drag the right control button for red vertically down, so the opacity control is basically horizontal, and zero.

Nothing happens. This is a bad bug.
Marking high since this is impacting me.

commit a6b0b0dfa9266f2387fe58a285360728bda23aa1

    BUG 0014283. Fix change events fired by vtkControlPointsItem.
    This commit consolidates the logic between all vtkControlPointsItem subclasses
    to consistently notify rest of the world that the control points were modified.
    Previously, commit 1509669d87 tried to do the same with
    vtkControlPointsItem::PointsModifiedEvent, however vtkCompositeControlPointsItem
    wasn't firing those consistently resulting in the BUG 0014283.
    While attempting to fix that, I noticed that vtkControlPointsItem has
    StartChanges()/EndChanges() methods that could be used for a similar purpose:
    notify the world that control points are being changed. Hence, remved the
    PointsModifiedEvent, instead fixing the code to consistently use
    StartChanges()/EndChanges() calls.
    Fixed StartChanges/EndChanges to fire the event on the vtkControlPointsItem
    (along with tranfer function, as it was previously) and added logic to avoid
    duplicable firing of events due nested calls to StartChanges/EndChanges.
