OpenHAB 2.4 - Weird Error-Messages while triggering some Items

Casshern · June 18, 2018, 4:02pm

Hello,
i am using Openhabian on an RPI 3b with the newest Openhab 2.4 Snapshot (#1302) and i am getting some error-messages while using some openocean-items (newest binding-version) which i can´t decipher. The items themself are working just fine and it is not just a specific group of items which are affected.
The thing and item-codes are correct and i have the feeling that it is not the bindings fault. Maybe something else broke while upgrading to each snapshot. Sadly i have no idea, when the error-messages started because everything worked and still works fine.

Here is the error-code:

17:43:06.266 [INFO ] [smarthome.event.ItemCommandEvent     ] - Item 'EG_Licht_Flur_2' received command ON
17:43:06.271 [ERROR] [rnal.common.AbstractInvocationHandler] - An error occurred while calling method 'EventSubscriber.receive()' on 'org.eclipse.smarthome.core.thing.internal.CommunicationManager@1aa6f3f': null

I have the smae problem with the SNAPSHOT
I have rolledback 2 versions

Please report this bug at https://github.com/eclipse/smarthome/issues.
If possible, add information about how to reproduce it - does it happen on ALL items and any event or what does it require to cause this exception?

sjka · June 19, 2018, 8:05am

Thanks! A fix is already on its way: https://github.com/eclipse/smarthome/pull/5754

Casshern · June 19, 2018, 11:32am

Thank you very much. I will keep you updated, after build #1303 is released.

Best regards,
Alex

triller-telekom · June 19, 2018, 2:23pm

Build #1303 will not include the fix. There has to be a new ESH stable build first, which is then pulled into openHAB. You can see if a new ESH stable was built here: https://ci.eclipse.org/smarthome/job/SmartHomeDistribution-Stable/

The openHAB version built after this new ESH stable will have the fix included.

@triller-telekom

Thank you. Good to know.

Best regards,
Alex

Casshern · June 28, 2018, 8:47am

Hello everyone.

I just installed #1305 and the problem is solved. Thank you very much

Best regards,
Alex

arins · August 21, 2019, 9:51pm

This happened to me. I deleted the items and recreated them and the problem went away
