Get former value from listpicker

MIT App Inventor Help
1

Have a problem when using listpicker and "sub menus".

If I choose "Sub1" from main menu, picklist LP_sub1 popps up, I choose A then global Selection gets value 333
If I do the same again, first then global Selection gets value A
If I after that choose "Sub1" from main menu, picklist LP_sub1 popps up, I choose B then global Selection gets value A
And the same again, I choose C and then global Selection gets value B.
Seems like global Selection does not gets the value for what I'm picking, it gets the value from what I picked just before the latest picking.

When I choose Sub3, everything works global Selection gets value G

Must be something with the call function I think but I cant understand what and how to fix it

Looks like it is working exactly as you have programmed it.....

As always :slight_smile: The question is how I shall program it to work as I want. To always get the value from the latest picking and not the one before

Here is another nested list picker sample ...

It is alway showing latest selection only, from subList, as I can see

Think I found my problem. Its not a problem setting global selection, everybody was right! The problem was the get function.

This doesn't work:

It seems like I can not handle the global selection inside the "AfterPicking function" it has to be done outside. Just like you illustrated RamNaresh.

But how can I do that without a button?

Thenks Taifun and ABG for the models of nested list pickers, much more flexible to work with!
