Does it show “Date 25.09.2018” or just the full ISO 8609 Date Time string? Or does it show "BlaBla " followed by the full date time string?
What version of OH are you running?
Does this problem persist after a restart of OH?
Well, the problem is the Docs are intended to be use together. If we had to mention every time something like this appeared in an example in the docs, they would be more than twice as long and almost impossible to maintain. So I’m not really sure I agree with adding the comment, because ALL Items are defined elsewhere. Using the “item” tag on a Sitemap element ALWAYS means you are referring to an Item defined elsewhere.
We can use a name that is a little less ambiguous.
That would be greatly appreciated. Reference this thread in the issue you create and the comments on your PR. You should be able to make the change in the browser.
I don’t see anything obviously wrong with the way you are setting up the formatting. If you don’t try to override the label in the sitemap and instead apply the formatting to the Item does it still fail?
You didn’t say you are using Habmin. Habmin hasn’t been kept up to date. There are large portions of it that don’t work. You should really only use Habmin for administering zwave and zigbee for now. I suspect it will be quite some time before chris gets a chance to go abck and make everything else work properly in Habmin again.
