Pushbutton is displayed as enabled but clicking it has no action. The pushbutton should be displayed as disabled.
In provided function’s panel, the button in question is disabled at runtime but due to different button’s text color – button does not look disabled.
The Protected state for button’s text color property is set to ‘0,0,128’ which is causing the problem.
Changing button text color property to ‘No Value’, will make button display in an expected way.
