I'm currently trying to display an icon in a data view. The configuration of the icon column is very simple, selectedValue is equal to 1 and the icon to be displayed is in the icon resources of the database. The xpages theme is currently set to Bootstrap4XPages. The page does not display in the browser. When I set the theme to OneUI, the page displays fine with the icon. Can anyone indicate a way to debug this? Here is a snippet of the error-log on the domino server. I removed most of the exception values to keep the post as short as possible. :
