[Typo3-shop] Problem extending tt_products

thanks for this information.
However this has the drawback that all TCA will be loaded in frontend
and not only that of the tt_products tables.

The error comes from


/**
	* Loads the $TCA (Table Configuration Array) for the $table
	*
	* Requirements:
	* 1) must be configured table (the ctrl-section configured),
	* 2) columns must not be an array (which it is always if whole table
loaded), and
	* 3) there is a value for dynamicConfigFile (filename in typo3conf)
	* Usage: 84
	*
	* @param	string		Table name for which to load the full TCA array part
into the global $TCA
	* @return	void
	*/
function loadTCA($table)	{
	global $TCA,$LANG_GENERAL_LABELS;
	if (isset($TCA[$table]) && !is_array($TCA[$table]['columns']) &&
$TCA[$table]['ctrl']['dynamicConfigFile'])	{
		if
(!strcmp(substr($TCA[$table]['ctrl']['dynamicConfigFile'],0,6),'T3LIB:'))	{
		
include(PATH_t3lib.'stddb/'.substr($TCA[$table]['ctrl']['dynamicConfigFile'],6));
		} elseif
(t3lib_div::isAbsPath($TCA[$table]['ctrl']['dynamicConfigFile']) &&
@is_file($TCA[$table]['ctrl']['dynamicConfigFile']))	{	// Absolute path...
			include($TCA[$table]['ctrl']['dynamicConfigFile']);
		} else include(PATH_typo3conf.$TCA[$table]['ctrl']['dynamicConfigFile']);
	}
}


So probably the
$TCA['tt_products'] = Array (
...
'dynamicConfigFile' => PATH_BE_ttproducts.'tca.php',

causes that only the tca.php from EXT:tt_products will be loaded only.



There should be a better solution to this where still only the TCA for
the tt_products table will get loaded.
