[SOLVED] Openhab rule java.lang.number problem

Setup, Configuration and Use Scripts & Rules
,
1

I’m using Alarm Clock script (link below) to make kinda my own schedule.
I think that it should work but i get this error.

var Timer timerPERSON1Wecker = null

rule "Termostat urnik"
when
    Time cron "0 0/1 * * * ?" // note, one could use an external event to trigger the rule if the alarm is implemented elsewhere (e.g. Tasker)
then
	logInfo("Urnik","Log3")
    val person = "PERSON1_WECKER_"

    var dayName= "NA"
    switch now.getDayOfWeek{
        case 1: dayName = "PO"
        case 2: dayName = "TO"
        case 3: dayName= "SR"
        case 4: dayName= "CE"
        case 5: dayName= "PE"
        case 6: dayName= "SO"
        case 7: dayName= "NE"
    }
	logInfo("Urnik","Log4")
    val person1On = gAlarm.members.filter[s | s.name == person+dayName].head.state
	logInfo("Urnik","Log5")
    if(person1On == ON){
        var sollMinute = (gAlarm.members.filter[s | s.name == person+"M"].head.state as Number).intValue
        var sollStunde = (gAlarm.members.filter[s | s.name == person+"H"].head.state as Number).intValue
        var runTime = (gAlarm.members.filter[s | s.name == person+"RUN"].head.state as Number).intValue
        logInfo("Urnik","Log6")

        if(sollMinute == now.getMinuteOfHour && sollStunde == now.getHourOfDay) {
            //sendCommand(person+"_AKTIV", ON)
            logInfo("Urnik","Log1")
            postUpdate("termostat1_zelena_temperatura", "25")
			
			if(PERSON1_WECKER_ONOFF.state == ON){
				logInfo("Urnik", "Log2")
				postUpdate("termostat1_zelena_temperatura", "25")
			}else{
				
			}
            // do stuff
            timerPERSON1Wecker = createTimer(now.plusMinutes(runTime), [|
                // do stuff
                timerPERSON1Wecker = null
            ])
        }
    }
end

In console log i get

15:26:00.016 [ERROR] [ntime.internal.engine.ExecuteRuleJob] - Error during the execution of rule Termostat urnik: java.lang.Number

Does anyone know what is wrong?

I’m going to guess one of your Number Items is uninitialized. Uninitialized Items have the state NULL (not to be confused with the all lowercase null). Since NULL is not a java.lang.Number you are getting an exception when you try to cast it to one.

That is just a guess. The code looks OK at a glance.

I’m not saying your Items do not exist. I’m saying they do not have a state yet. They are in an uninitialized state. You need to give them a state before the rule above will work or you need to test that their states are not NULL before blindly trying to cast them to Number.

On your sitemap uninitialized Items will appear with a state of -.

Number PERSON1_WECKER_RUN

This one was null and now it works.
Thanks again! :slight_smile:
