Hi Tim,
Fix contained in upcoming JMRI release 15.7
The Light Controls showing this message in JMRI 14.4 OpenLCB will still operate, it's just that the very first Light ON command may not trigger correctly.
This shouldn't be much of a problem with a FastClock at 90x speed, it'll just get updated 0.6 seconds later than normal on startup.
More of a problem with Light Controls that use a Sensor or Turnout as an input trigger, but at least you get an error popup if there's an issue!
I've only got a v basic knowledge of OpenLCB so not sure about the Light table interface thing.
Perhaps write up the feature request in more detail on Github to inspire one of the developers more fluent in OpenLCB?
Steve.
