Rule not working correct after change a item

[steffe (Steffen)]

Hello all

• Platform information:
  • Hardware: Raspberry Pi 4 Model B Rev 1.1
  • OS: openhabian
  • openHAB version: 3.0.1 - Release Build

If I change a item, the rule will not work correct. Here I show you my steps, at the beginnig everything is fine:
Item file:

Switch SW_Test                      
String Str_Test                     // { expire="5s,Noooo" }

Rule file:

rule "Test Rule"
when
    Item SW_Test changed
then
    Str_Test.sendCommand("Yesss")
end

After SW_Test changed I got these Log:

23:39:19.316 [INFO ] [del.core.internal.ModelRepositoryImpl] - Loading model 'Test.rules'
23:39:25.161 [INFO ] [openhab.event.ItemCommandEvent       ] - Item 'SW_Test' received command ON
23:39:25.168 [INFO ] [openhab.event.ItemStateChangedEvent  ] - Item 'SW_Test' changed from OFF to ON
23:39:25.176 [INFO ] [openhab.event.ItemCommandEvent       ] - Item 'Str_Test' received command Yesss

Til now OK
And then I change the item Str_Test to:

String Str_Test          { expire="5s,Noooo" }

In Test Rule nothing changed and the Log look like this:

23:44:15.368 [INFO ] [del.core.internal.ModelRepositoryImpl] - Loading model 'Test.items'
23:46:06.284 [INFO ] [openhab.event.ItemCommandEvent       ] - Item 'SW_Test' received command OFF
23:46:06.289 [INFO ] [openhab.event.ItemStateChangedEvent  ] - Item 'SW_Test' changed from ON to OFF

Why does not change the item Str_Test?
Now I must change something in the rule file that Test.rules is loading und after that it works fine.

rule "Test Rule" // tutututut
when
    Item SW_Test changed
then
    Str_Test.sendCommand("Yesss")
end

23:51:48.124 [INFO ] [del.core.internal.ModelRepositoryImpl] - Loading model 'Test.rules'
23:51:55.023 [INFO ] [openhab.event.ItemCommandEvent       ] - Item 'SW_Test' received command ON
23:51:55.031 [INFO ] [openhab.event.ItemStateChangedEvent  ] - Item 'SW_Test' changed from OFF to ON
23:51:55.042 [INFO ] [openhab.event.ItemCommandEvent       ] - Item 'Str_Test' received command Yesss
23:52:00.304 [INFO ] [openhab.event.ItemStateChangedEvent  ] - Item 'Str_Test' changed from Yesss to Noooo

That means whenever I change a item I must reload all rule files? It can’t really be, can it?
I allready clean the cache and reboot the Raspberry. I also replaced sendCommand with postUpdate but the same behaviour

Yes. Editing an file created Item causes a loss of “connection” to file created rule triggers.

OH3 (Possible) DSL Rules, received update not firing from different files

That goes a long way to explain many troubles people have had, thanks for playing with this. While a rule that does not trigger from a newly created Item can be waffled away, I don’t think editing Items causing rules to break is expected behaviour. I’ve updated an existing Issue with your findings, clearly removing Groups from the picture.

For now, to recover you edit/reload the rules file.

@steffe

I allready clean the cache

Avoid doing that if you can, it generally causes more problems at the next restart until populated again.

Thank you. Good to know that I’m not alone
I already thought I had forgotten everything about items and rules again.
