I have a dashboard which has several list widgets.
I am trying to edit the filters on the list widget using the Edit Filters button in the Widget Properties.
Each time I click this button it takes progressively longer to load the filters.
At first it takes about 5 seconds, but next time you click it, it will take 10 seconds.
Eventually you get a Page Unresponsive error.
DX UIM 23.4.2 Operator Console
Dashboard Designer portlet
This will be resolved in DX UIM 23.4.3 (CU3) which is due to be released in early 2025.
As a workaround, save the dashboard and refresh the page after editing the filters. The filter editor will go back to normal speed after a page refresh.
