[TYPO3-dev] Display a plug-in's field in the content element form

[Francois Suter]

Answering to myself in case it helps another lost soul...

As a last resort I started from scratch again and the code that does the 
job is:

t3lib_div::loadTCA("tt_content");
t3lib_extMgm::addTCAcolumns("tt_content",$tempColumns,1);


t3lib_div::loadTCA('tt_content');
$TCA['tt_content']['types']['list']['subtypes_excludelist'][$_EXTKEY.'_pi1']='layout,select_key';
$TCA['tt_content']['types']['list']['subtypes_addlist'][$_EXTKEY.'_pi1']='tx_myext_confirmation_page;;;;1-1-1';
