Hi, [my custom layout](https://github.com/SlicerIGT/SlicerBoneReconstructionPlanner/blob/ee133884bc126d4d593612bd90211fe2e3165625/BoneReconstructionPlanner/BoneReconstructionPlanner.py#L155-L179) has 2 threeDViews.

This layout is available in the layout menu after Slicer starts up but, apparently, I cannot access the second threeDView until the custom layout has not been set once.  
This is a problem because I want to automatically create some nodes that should only be visible in the 2nd threeDView and I can’t because an error tells me the 2nd threeDView is `NoneType`

Hope you can help

You can set the view node IDs in the display node before those views are created.
