OH3: oh-button-action-toggle not finding Item

[Vetri (Tobias H.)]

So, right now I’m questioning my sanity.
I want to create a simple button, that toggles an Item.
By now, i have direktly copied the example from the documentation and just replaced the Itemname with the Name of my TestItem:

uid: oh-button-action-toggle
tags: []
props:
  parameters:
    - context: item
      description: Select the item to use with these buttons.
      label: Item
      name: item
      required: true
      type: TEXT
      groupName: general
  parameterGroups:
    - name: general
      label: Display options
timestamp: Mar 6, 2022, 12:47:11 PM
component: f7-card
config:
  title: "oh-button > action: toggle"
  footer: Set the properties to any item that accepts an ON/OFF commands
slots:
  default:
    - component: f7-block
      config:
        class: bog
        style:
          display: flex
          flex-wrap: wrap
          justify-content: space-between
          align-content: space-between
          padding: 20px
      slots:
        default:
          - component: oh-button
            config:
              text: Off
              outline: true
              action: toggle
              actionItem: =TestItem.item
              actionCommand: ON
              actionCommandAlt: OFF
              style:
                width: 100px

This should (in theory) toggle the following Item:

I already doublechecked that it exists and is listed in the Items-section of the UI.

And yet, when I click on the Button, i only get the following Message:

in written Form:

[WARN ] [e.internal.SseItemStatesEventBuilder] - Attempting to send a state update of an item which doesn't exist: TypeError: n is undefined

Already rebooted the Raspi and tried with different items, Itemnames and whatnot…
I can already guess, that it’s something obvious I’m not seeing here,but…well…I’m not seeing it…

So thanks in advance to everyone who can help me stay sane with this.

@Vetri

actionItem: =TestItem.item

Either you select

actionItem: =props.Item

since this is the item defined in the properties section,

or you just write

actionItem = TestItem

if you want to have it static and not selectable with the widget’s properties

Alright, got it to work.
It seems I was so focused on the slots-part, that i compleatly missed the props…
Thanks
