Hello XAF Team,
In XAF Web UI, callbacks (ImmediatePostData) may cannot execute successfully in inline mode of ListView.
Until this issue is fully fixed, we cannot use list views in inline edit mode, simply because it lacks callback (ImmediatePostData) support.
To learn how to re-produce this issue, please see the attached simple VS solution + screen video (3 min length).
Note: I reported this issue first in Q472180, but it was a different problem than the original ticket topic. So I created this separate ticket to help you track it.
Regards,
James
