Problem summary Within Nuke, attempting to undo a newly created knob expression link does not remove the Node Graph expression link. The expression is removed as expected, yet the link stays in the viewport.
Looking up the dependency with the following snippet, displays the nodes are still dependant:
2) Change the Multiply on the first Grade node to anything ( 0.5 for this test )
3) Using the animation curve icon, CTRL+Left-Click drag and drop the icon into the second Grade node's Multiply knob.
The nodes should be linked with an expression.
4) Undo the last option.
Result: The expressions are undone, yet the links are still displayed on both objects.
Expected behaviour Undoing an expression should remove the expression link
Actual behaviour Undoing the expression leaves the expression link.
Workaround Modifying the knobs which were given the expression link, removes the link. Please Note: This appears to only occur in Nuke11.1v2 and higher.
