@linawolf, I've just had a look at whether [tree.level = X] is working as [treeLevel = X] used to do for PageTS. We usually use this to show certain fields only on site root level, e.g. is_siteroot, backend_layout and backend_layout_next_level.

Hide certain fields globally:

TCEFORM.pages.is_siteroot.disabled = 1
TCEFORM.pages.backend_layout.disabled = 1
TCEFORM.pages.backend_layout_next_level.disabled = 1

But show them on root pages (old syntax):

[treeLevel = 0]
TCEFORM.pages.is_siteroot.disabled = 0
TCEFORM.pages.backend_layout.disabled = 0
TCEFORM.pages.backend_layout_next_level.disabled = 0
[global]

Which translates to the new syntax:

[tree.level == 1]
TCEFORM.pages.is_siteroot.disabled = 0
TCEFORM.pages.backend_layout.disabled = 0
TCEFORM.pages.backend_layout_next_level.disabled = 0
[global]

As you can see, there's a difference in what's considered to treelevel 0. In my opinion that's a bug.

Another thing is that for nested sites the treelevel is not reset even though there's a sys_template record with root=1 set that is processed correctly in FE TypoScript.

So to make the snippet work for PageTS we gotta use this for a root site that's located on absolute treelevel 3:

[tree.level == 4]
TCEFORM.pages.is_siteroot.disabled = 0
TCEFORM.pages.backend_layout.disabled = 0
TCEFORM.pages.backend_layout_next_level.disabled = 0
[global]

@kitzberger did you make an issue on https://forge.typo3.org/projects/typo3cms-core/issues about this? This sounds like a bug indeed

@linawolf, not yet, but now: https://forge.typo3.org/issues/96385

I will close this until the Core Issue is resolved
