All annotated points are exported as "Interphase"

[bramthijssen]

When I tried running the code in the A_CNN_Annotation_with_Napari.ipynb" notebook, I could add points and change their state; but when exporting the data, all cells received the "Interphase" state regardless of their color/state.

It looks like the "current_properties" of the napari points layer is not actually updated. I think this line should do that:
points_layer.current_properties['State'] = np.array([current_state.value])
But that line doesn't actually change the current_properties, at least not with the current napari version. I believe it is not working because it's retrieving the current_properties dict, and then modifying the local value, rather than the member of the points_layer. Changing that line to this:
points_layer.current_properties = {'State': np.array([current_state.value])}
seems to make everything work again. I guess this will use the current_properties setter function instead of the getter function. Perhaps these things changed in a recent napari version?

I'm not confident enough to submit this as pull request though
