Selection box missing when redoing after delete all

[leemi]

1. Create multiple strands.
2. Select all strands
3. Delete.
4. Undo until it's a blank document
5. Press and hold Ctrl+Shift+Z to redo

// Error: underlying C/C++ object has been deleted

Calling the pathview directly from the mayaview is a no no

File "c:\git\cadnano2\controllers\mayacontrollers\mayaObjectManager.py", line 156, in strandsSelected
doc.win.pathroot.clearStrandSelections()

Fixed the hack

Nick, there was a reason why I had this hack:
XXX [SB] THIS IS A HACK, should not need to do this!!!
doc.win.pathroot.clearStrandSelections()
the Maya to Cadnano selection does not work right without it...removing that line does not solve the underlying issue...

[grinner]

Okay, so there's other issues. Tryingn to track down. I suspect the views just need a reset

[grinner]

Please test

I think I solved it. Basically the press callbacks need be minimized.
Until that happens, we may have issues. I think I can push a fix as
the work I did the other day can revert the complexity of my
mousepress callback business

Doesn't seem to be working for me, when I deselect in 3D view, the items are still selected in 2D view.

[grinner]

So we need an way to set self.oldSelectionStrandList. That is it seems like we need to catch the deselected items and map them to strands in the model

[grinner]

or, I can just add a method to the model to deselect everything globally. You guys' call, but I'd like a way to do the former, as that is how I do it in the pathview
