TYPO3 Core

I can confirm that!

On a 4.2 Version the TSConfig:
TCEFORM.tt_content.media.config.maxitems = 20
is working very well.

I tested it on a 4.3.3 Version: not working

and on a 4.4.2 Version: not working

same problem with pages.media on TYPO3 4.4.2
the size btw is possible to override.

[edit] -> the size of the group-box. (the filesize i did'nt test)[/edit]

Same here with TCEFORM.pages.*:
TCEFORM.pages.media.config.maxitems = 10 don't work on TYPO3 v. 4.4.4

Hi, the problem does still exists in 4.5.30

I can confirm this problem still exists in 4.7.14

If you are on the way, could you please also fix this one in 4.5.X: https://forge.typo3.org/issues/26142
it seems a nobrainer.

TCEFORM.pages.media.config.maxitems = 10
works on 6.2/master now.

This works as expected in TYPO3 6.2.5:

TCEFORM.pages.media.config.maxitems = 20
TCEFORM.tt_content.media.config.maxitems = 20

This doesn't work as expected in TYPO3 4.5.39:
(After saving some files are lost)

TCEFORM.pages.media.config.maxitems = 20
TCEFORM.tt_content.media.config.maxitems = 20
