Disappearing network editor background image - Python

[Dubidu]

Hello,

When I copy and run the following code in a python sop node,

editor = hou.ui.paneTabOfType(hou.paneTabType.NetworkEditor)
image = hou.NetworkImage()
image.setPath('$HFS/houdini/pic/Mandril.pic')
image.setRect(hou.BoundingRect(0, 0, 5, 5))
editor.setBackgroundImages([image])

(which can be found here in the sideFX documentation: https://www.sidefx.com/docs/houdini/hom/hou/NetworkImage.html )

it does indeed create the background image in the network editor. However, should you change context and then go back to the sop context where you created the background image (example: /obj/geo/python >>> /out >>> /obj/geo/python), it will have disappeared. This doesn't happen when creating the background image through the network editor's dedicated button, but I need to be able to do it with python, because I'm setting up a shelf tool template that would need to do this. Any idea why the image is disappearing with the python script?

Thanks

 

Attached is a simple scene with the python node set up. Just activate the python node, see the background image pop in place, change context, go back, and see that the background image has disappeared.
