I have a LightwaveRF switch with the following configuration:
String My_Switch { rfxcom="<15934579.1:RawData" }
And then the following rule:
rule "My Rule"
when
Item My_Switch received update
then
logDebug("My.rules", My_Switch.state)
end
However when I press the switch I get the following message in the debug logs:
18:36:40.970 [INFO ] [runtime.busevents :26 ] - My_Switch state updated to 0A140086F38DEB010F0070
18:36:40.971 [DEBUG] [m.r.internal.engine.RuleEngine:305 ] - Executing rule 'My Rule'
18:36:40.971 [DEBUG] [o.o.i.m.i.MyOpenHABServiceImpl:262 ] - store(My_Switch), state = 0A140086F38DEB010F0070
18:36:40.975 [ERROR] [o.o.c.s.ScriptExecutionThread :50 ] - Error during the execution of rule 'My Rule': Could not invoke method: org.openhab.model.script.actions.LogAction.logDebug(java.lang.String,java.lang.String,java.lang.Object[]) on instance: null
So it is my understanding that it updates the state of the item but when I try and access it in the rule it returns null which causes the log to throw an exception.
What am I doing wrong?
