[SOLVED] - Refreshing a repeater widget

[Andrew_Pawelski]

I have a MainUI widget that has a repeater in it looking at a collection of tagged items and it renders nicely but fails to refresh when one of the items refreshes

I found this:

Auto-refresh charts and widgets in MainUI

As people migrate over to OH3 and the MainUI from other UIs, many are surprised to find that MainUI charts are static on a loaded page and won’t refresh unless the page is reloaded. Here I’m providing a fairly simple solution that allows you to set up timed, automatic refreshes for charts on a page (or another widget that you have configured with custom content that doesn’t refresh). When Do Widgets Refresh? So many of the standard widgets and components do respond to changes in item states …

butit doesnt refer to repeaters - can anyone tell me if this applies to them

It sure does. You can see an example of applying it to a repeater here:

Dynamic Favorites Bar

I’m putting this particular widget up not because I think that there will be too many people with a use case for it, but because it contains many smaller parts and workarounds that others might find a use for in their own work. The widget itself allows for the dynamic addition and removal of other simple, single item widgets. This happens on a live page, not in the UI page editor. This gives other OH users who do not have an administrator account some control over the items that are directly …

You still need an event that changes the actual state of an item or items so that the key property changes and triggers the refresh, so if the item tags themselves are the only thing changing that’s not enough to trigger the change.

Perfect! I used the key config item with Math.random and as I am trying to refresh repeater items in a calendar, the icalendar thing has a last updated channel - so I have based it off of that - I guess it updates regardless of any change or not but it works great!
Thanks for the info!
