[BUG] Treeview container

[milia20]

Hi. I found problem with Treeview container. In native components we have Treeview container, when i want to change attributes -> show from base value tree to headings formation studio saves information in xml, like attr:show="('headings',)" And this raise error

Steps to reproduce the behavior:

1. Place Treeview container
2. Change attributes - show from tree to headings
3. Save file
4. See error

• OS: Win 10
• formation Version 0.6.3
• Python version: 3.10.4 and 3.12
• tk version: 8.6

After changing xml file "('headings',)" -> "headings" Works fine, error is gone.

@milia20 thanks for using Formation. I too have encountered this issue before. I will look into it and try to get a fix.
