Problem summary

Customer reported version
Mari 4.7v6
 
Customer reported platform
n/a
 
Steps to reproduce
 
1) Open any project

2) Create a Cloud node, connect it to a Grade node and view the result

3) in the Grade node's properties, press the 'S' button next to the Gain slider to split the property into component mode
 
4) Change the component values and observe the result in the viewport
 
5) Press the 'R' button
 
Expected behaviour
Editing the component values should affect the result.
Pressing the reset button should revert the values to default.
 
Actual behaviour
Editing the values has no effect on the Grade's result in the viewport
Pressing the reset button has no effect.
 
Workaround
Individual Vector4f components can be edited via Python using the node.setMetadata() command, e.g. node.setMetadata('Gain', (1,0,0,1))
Please note that this workaround does not work in Mari 4.8 and 5.0 due to bug ID 506392
