Hi Bob,
I tried to use the SignalFollower.py script, but get errors logged.
Information from the log:
PanelPro version 4.6-R81496dc starts under Java 1.8.0_77 on Linux amd64 v4.4.0-79-generic at Sat Jun 17 13:22:37 CEST 2017 [main]

My Script:

class SignalFollowerListener(java.beans.PropertyChangeListener):
def set(self, inputName, outputName) :
self.inSignal = signals.getSignalHead(inputName)
self.outSignal = signals.getSignalHead(outputName)
self.inSignal.addPropertyChangeListener(self)
return
def propertyChange(self, event):
self.outSignal.setAppearance(self.inSignal.getAppearance())
return
# Example of use - add a line like the following
# that includes system or user names for the signal head to be repeated,
# and the signal head to repeat it onto. These must already exist.
# SignalFollowerListener().set("CH2001","CH2001R")
# SignalFollowerListener().set("CH2002","CH2002R")
# SignalFollowerListener().set("ih1","ih4")
SignalFollowerListener().set("SBB Main 3","SBB Vorsignal")
I've tried with both the system name and the user name: both fail.
Have I missed something in the set up?
Do the scripts in the jython folder of JMRI.4.6 get run at start up? If so have I created a duplicate class?
Regards
Otto
