[OH3] Add metadata to Items via configuration files

State Description

Via the UI, the following options are available:

To populate these fields via configuration files (example values):

Number nTest "Test Number Item" {
	stateDescription=""[
		pattern="%d%%",
		min="0",
		max="100",
		step="1",
		options="1=Red, 2=Green, 3=Blue"
	]
}

Thanks!

UPDATED: However… it does not work on openHAB 3.0.2. The language parser chokes on this format of stateDescription metadata. Maybe it’s the empty double quote portion that is the culprit, as also mentioned in:

How to add item pattern format via "Add items via textual definition"?...

More precisely:

The trick is, to add the pattern as metadata in the textual definition. E.g. , stateDescription=" "[ pattern="%1$tR" ] (Make sure you have a space or some other text in stateDescription=" " / Empty does not work)

(The example successfully assigns and properly configures the custom temperature_list widget for list items, but skips the offending stateDescription metadata definition block.)

It however works when adding a single space between the pair of double quotes.

Bug report:

Cannot assign stateDescription metadata in Item creation from textual definition
