TYPO3 Core

K, this error comes up if I uninstall
css_styled_content; it seems the felogin
is more dependent on csc as I thought.

The problem in detail is, that "addTcaSelectItem"
tries to load the TCA for tt_content, but fails to
load the whole TCA, because before somewhere in
another extension, the TCA array is filled with
some configuration, without loading the whole
TCA before.

Meaning, "loadTCA" only loads the TCA, if the
TCA[$table] array is EMPTY, but if some extension
pre-populates TCA[$table] with any data, "loadTCA"
just won't load the default/whole TCA.

Thats why the code in "addTcaSelectItem" throws
an error - because the TCA['tt_content'] is available,
but the column 'CType' is not available inside it.

The same problem seems to occur for the form extension.

This extension also adds values to the TCA array but does not call loadTCA() before that.

Maybe this can be included in the pending patch?

After digging into this I figured out two things.

First: the problem is not caused by css_styled_content. At the beginning of it's ext_tables.php file it calls

\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addPiFlexFormValue('*', 'FILE:EXT:css_styled_content/flexform_ds.xml', 'table');

This calls \TYPO3\CMS\Core\Utility\GeneralUtility::loadTCA('tt_content'); at the beginning, so another loadTca() would be superfluous.

Second: The problem can only be reproduced, when the extensions are loaded in a defined order. Put this order into you LocalConfiguration.php file:

'form',
'css_styled_content',
'felogin',

Now you can clear all caches and reload your Frontend. You will see the exception.
