Bad arguments to select list item

[ABG]

@h_h

The TinyDB1 of the Screen1 and that of the Screen2 are different in the real phone, and that shares together in the emulator.
Was it correct I understood?

In both cases, it depends on the Namespace value of the TinyDBs, which determines the XML file name used for Tinydb components.
If you have not changed the default Namespace value ("TinyDB1"), you should find the same TinyDB1 in all screens of an app.

Your initialization error in a real device is probably caused by using an inappropriate notfound value in your initialization loads from TinyDB1, like a blank text block where an empty list is warranted.
