can't reproduce on linux, trying mac...

works on mac 2012-09-27

The crash does not happen, but the scene does not restore properly either. See attached image: The sceneview restored in 10-20 nightly on mac and the thumbnail from the sceneview png file.

1. the fiducials are not visible
2. the label map is not rendered as outline, but as solid
   From a user perspective, both of these are serious issues that essentially make the sceneview useless.

and yes, the crash does not happen anymore.

1. in the .mrml file, the annotation display nodes have their visibilities set to false, while the annotation nodes have their deprecated visible flag set to true. The display node settings are being used now rather than the flag on the fiducial nodes. See the attached new mrml file with the display node settings toggled, 2012-10-23-Scene.mrml

2. is probably due to the changes in the way linking slices works, some of the slice composite nodes in the scenes have linking turned on, and some of the label volumes have outlines on and some off, and some settings are getting over written due to the linking. Debugging print out from restoring a the tumor crosssection scene view:

According to "git log --author=millerjv --grep=link" I have fixed this problem twice before.

2/10/2010 #6543396fb, r12232

2/21/2012 #f6dada754, r19319

So it looks as though I am not scheduled to fix it again until 2/2014.

I will take a look at what has been changed since r12232.

r12232 introduced priorities so that SliceLinkLogic would be last things to be notified when restoring a node, so that link behavior would fire last. It also keeps a counter on how deep events are being broadcast.

The idea behind r12232 would be that linking behavior would not trigger while restoring a scene/view since all nodes should be properly re-populated directly from the data model.

Label outlines in Scene View restore are fixed in r21238.

Label outlines were not being managed by the SliceLinkLogic which properly manages broadcasting linked parameters during restore operations. Rather, label outline was being managed directly by qMRMLSliceControllerWidget.

Annotation visibility is still not managed properly. This is outside of the SliceLinkLogic control.

r21238 just fixed the label outline linking. There are other parameters that still being managed by the qMRMLSliceControllerWidget that should not. I will enter a bug on the other parameters that are being managed by qMRMLSliceControllerWidget but should be managed by SliceLinkLogic.

Slice visibility in Scene View restore are fixed in r21239.

Slice visibility and label outline issue has been fixed.

Annotation visibility is (according to Nicole) an issue with the scene file. See note 0006696.
