Problem summary:
Group knobs show_group_view and disable_group_view do not update correctly when driven by expressions
Customer reported version:
Nuke 16.0v4
Customer reported platform:
Windows N/A
Steps to reproduce:
1) Launch Nuke and create a NoOp node in the Node Graph
2) In its Properties, right-click and navigate to Manage User Knobs... > Add > Check Box
3) Give the Check Box a name, such as "test"
4) Create a Group node in the Node Graph
5) In its Properties, right-click on the Show Group View knob and select Add Expression...
6) Point the expression toward the NoOp node's Check Box, by entering NoOp1.test for example
7) Toggle the NoOp's Check Box on and off, observing that although the Group's Properties display the correct result, the Group View is never actually opened in the Node Graph:
Expected behavior:
Group View knobs such as show_group_view and disable_group_view should accept expressions and update appropriately whenever the state is changed.
Actual behavior:
The show_group_view and disable_group_view knobs will accept expressions, but changing their state via expressions will not update the Node Graph.
Workaround:
No known workaround at this time.
