TYPO3 Core

The problem still exists today (TYPO3 4.7.4) and definitely is a problem with the (classical) "New content wizard" only (the TemplaVoila wizard is not affected though). I could track it down to the following reason:

For each registered wizard item (mod.wizards.newContentElement.wizardItems.xxx.elements.xxx) the wizard checks for each given tt_content default value (tt_content_defValues.xxx) if the value part is present in the keepItems list. Now imagine the wizard definition of the "textpic" item (PHP representation):

array(
    [icon] => gfx/c_wiz/text_image_right.gif
    [title] => Text und Bilder
    [description] => Eine beliebige Anzahl von Bildern mit umfließendem Text.
    [tt_content_defValues] => Array
        (
            [CType] => textpic
            [imageorient] => 17
        )

)

Given the above, the wizard does not only check if the (CType value) "textpic" is contained in the keepItems list, but also looks for the number "17" (default value for the "imageorient" property).

The short term solution is to simply add "17" to the keepItems list:

TCEFORM.tt_content.CType.keepItems = textpic,17

The wizard will then show the "textpic" element as expected. Similar would have to be done for any other default value defined for any wizard item you want to be shown.

Of course this is not a valid long term solution and could also lead to unexpected side effects. At long sight the wizard has to be patched to only check for the CType default value, which would be pretty easy and straightforward.
