Error in createTimer: org.quartz.core.JobRunShell & org.quartz.core.ErrorLogger

Bagunda · December 12, 2020, 12:32pm

I don’t understand this error.

rule "Test1"
when
    Item V_balk_komn_lev received update
then
    TimerEnd.postUpdate("ON")
    val myTimer = createTimer(now.plusSeconds(5), [|
        TimerEnd.postUpdate("OFF")
        myTimer = null
    ])
end

Hasn’t myTimer to be a global variable ?

5iver · December 12, 2020, 8:38pm

What is the point of setting the timer to null?

Bagunda · December 14, 2020, 8:22am

There are many such examples in the community.openhab.org

rossko57 · December 14, 2020, 12:07pm

Yes, but you have not followed the examples.

val myTimer = createTimer(now.plusSeconds( ...

This creates a timer to run in the future, and keeps a reference or handle for it in your variable myTimer.

Then your rule ends, and any variables created within it are discarded and destroyed. Variable myTimer no longer exists.

Some time later, your timer runs.

myTimer = null

That line fails because variable myTimer does not exist.

Just as @Wolfgang_S said, if you want to do this kind of thing you will need to use a global variable, which are defined and created outside of any rule.

Bagunda · December 15, 2020, 8:41pm

Deleting the line “myTimer = null” didn’t help.

have you tried to make myTimer a global variable by putting

var Timer myTimer

in the first line of your rule file ?

rossko57 · December 16, 2020, 10:45am

But your timer code is now not what you showed us to begin with, is it?

The error message shows that your timer code now includes a line like
val sendTelegramAction ...
and that is failing.
It’s possible you’ve messed up the brackets and the timer code now accidentally includes parts of a following rule or something, but we can’t tell unless you show us what you are actually doing.
