There seems to be a regression in 8.1.5 where the numeric entry field does not apply a style properly:
This is a known regression in 8.1.4 and will be fixed for the 8.1.5 RC. Actually, the fix was merged today, so it should be available in the next 8.1.5 nightly.
I’m on 8.1.4
Since the last update I got issue with classes on disabled numeric field component.
I use project Styles to set component classes, so when the numeric field is disabled my background classes is bypassed with the default disabled classe of the component. Before that update i was able to set the backgroundColor with my custom style.
