Hi Bob,
I got the signal mast follower to work (almost).
I set the SignalMastFollower script to run at startup, where it fails with:
AttributeError: 'NoneType' object has no attribute 'addPropertyChangeListener'
If I open the panel then execute the script again, the signal mast following works.
Have I missed something in the set up? - it seems the script is being run too early.
BTW: There's an error in the script. On the last line (the example) it should read SignalMastFollowerListener and not SignalFollowerListener.
Regards
Otto
