In my relatively fresh OH3.1 installation on RPi4, I have created a rule in the GUI. The rule has two triggers, each of them of type item receives a command and and action in form of a DSL script - basically, I am just trying to replicate this rule.
My problem is that in the script,
null, so accessing
triggeringItem.name fails with error message that
getName() cannot be used on
null. I need this in order to find out which of the two items triggered the rule.
On the other hand
receivedCommand works as expected.
What am I doing wrong?
triggeringItem is only present (in OH3) when you use “Member of Group” type triggers.
triggeringItemName is available for ordinary Item triggers.
Thanks a lot.
I was confused by this documentation - possibly not updated for OH3?
Unfortunately that repo is not and cannot be updated for OH 3. See https://github.com/CrazyIvan359/openhab-helper-libraries for a fork that includes updates for OH 3.
event Object really. The variables are injected into the Rule’s context directly.
Hi Rich, I understand why you wonder, but it seems quite logical at the time: I had tried to replicate one of the design patterns in the forums, got an error, searched for it, and somehow ended up on the documentation site I was referring to. It seemed to confirm that what I was doing (using
triggeringItem.name in the rule) should work, so I posted a question to the forum.
In retrospect, I should have read the documentation instead of searching, I will try to remember it next time…
