You have a Listview.Selection with the selected option from listview, which you can use like tag. Your "selection" variable seems to be empty...

This variable receive value from another screen,but I show only blocks where I cannot find out what happends.Practically I use listview later for showing tags,but still here tinydb erase global selection,but clouddb doesn't.

Actually this is the real screen.I tried to simplify blocks.

You are missing this event block:
component_event

If you don't want that tag to appear in a taglist after issuing a clear tag,
don't ask for the taglist immediately, but instead ask for the taglist inside the .UpdateDone event, when you are sure it is gone.

Now is OK.But why when I switch on another screen and try to retreive tags again the result is unexpected.

Sorry.My mistake-I didn't enter the same credentials for redis cloud on each screen.
Thanks.
