unexpected "unable to sample node at given location (583, 87) for the current context" in customer script that worked for them in Nuke9.0v4 but fails in Nuke9.0v8
Support repro'd failure in Nuke9.0v8 and showed correct behavior in Nuke9.0v7 on OS 10.10.5
1.
open script RGBPosReadBug.nk
2.
connect the Viewer input to the group MEP_HSVKeyer; connect a second Viewer to the Colorwheel and show both Viewers
3.
open the group MEP_HSVKeyer control panel and show the group
4.
switch the node graph to the shown group and open the "loc" node's control panel; ; EXPECTATION is that the "sampled" knob shows non-zero values initially; in Nuke9.0v8 the values are zero and in 9.0v7 they are non-zero and correspond to the color values at initial location (583, 87)
9.0v8 yields an error in the terminal:
[15:34.15] ERROR: MEP_HSVKeyer.loc.sampled: unexpected '"' in ""unable to sample node at given location (583, 87) for the current context (may be zoomed in or have a ROI set)""
and you get a similar one if you look at the expression on the loc node's sampled knob
5.
on the MEP_HSVKeyer panel, enable the color picker on the "Pick Color" knob and sample the Colorwheel
6.
EXPECTATION is that the "sampled" knob in the "loc" panel shows non-zero values corresponding to the new color at new picked location x,y ; this works in Nuke9.0v7 but in 9.0v8 the values remain zero
