TYPO3 Core

Don't think this is a bug, the hidden flag is simply being inherited by the page above it, which will override the TSconfig you posted above, you can use the below TCA below to remove the hidden field from this list of fields which get their value inherited, just remove 'hidden' from the list.

$TCA['pages']['ctrl']['useColumnsForDefaultValues'] = 'doktype,fe_group,hidden';

I've put in ext_tables.php:

$TCA['pages']['ctrl']['useColumnsForDefaultValues'] = str_replace(array(',hidden', 'hidden'), '', $TCA['pages']['ctrl']['useColumnsForDefaultValues']);

but it still doesn't work.

I think that in Live workspace there has to be hidden page as default always, until the whole page is completed. Then you can un-hide it.
