TYPO3 Core

After unchecking a parent node no checkbox is checkable anymore. In 6.2.22 the select treeview is currently in an unusable state.

This problem only seems to occur with maxitems set.

In my tests (with sys_category) I encountered the following situations:

- maxitems: 1
1 item is selectable, but a exclamation mark appears when selected. When unselected, no item is selectable.

- maxitems: 2
1 item is selectable, if the tree is loaded with 1 item preselected 2 items are selectable.

- maxitems: 3
2 items are selectable, if the tree is loaded with 1 or more items preselected 3 items are selectable.

- maxitems: n
(n -1) items are selectable, if the tree is loaded with 1 or more items preselected n items are selectable.

(If the tree is loaded with some items preselected and all items are deselected n - 1 items are selectable).

I encountered the same issue. This issue is caused by fix for #75519 (Flexform select rendermode tree doesn't respect collapsed nodes).

I've just made a oneline patch and will commit it in the next minutes.
