Support solved the problem. In my select expression i’ve split a list into a list which causes the issue. here is the full answer:
As we can see, you have used an expression “SELECT(Anhang_Public_ro[ID],IN([ID],SPLIT([_THISROW].[Anhang],”,“)))” in your virtual column [Beilagen], this is causing this particular issue.> > This behavior is displayed because the expression used by you is returning an empty list due to [_Thisrow] being used, since [Anhang] is already a list then passing it directly without SPLIT() would work smoothly. Also, changing the update mode was displaying the data because it was an empty list displayed, that is why the count was shown as 0. But as soon as “ADD” was enabled it made the inline view ready to get populated that is why it was displayed.> > So, please try changing the expression which would resolve your issue and if you face any further issues please feel free to contact.> > Thanks,> > AppSheet support team
