So I may be missing something quite obvious, but I've been stuck on this for the past day.
I've got a source listbox with a destination listbox to the right. Let's say the datasource of the source listbox is optionList, and the datasource of the destination listbox is selectionlist. It appears selectionList does not get populated with the items moved from the source to destination listbox.
Am I looking in the wrong place to find the output list? It seems this is a new(er) feature so documentation and forum posts are light. I appreciate any help, thanks!
