[TYPO3] TYPO3 Fatal Error: Extension key "tt_products" was NOT loaded! (t3lib_extMgm::extRelPath)

Hello Michael,

$EM_CONF[$_EXTKEY] = Array (
	'title' => 'Shop Categories',
	'description' => 'Enables hierarchical categories for products. Works 
with every version of tt_products and table.',
	'category' => 'misc',
	'shy' => 0,
	'dependencies' => 'tt_products',

It uses hooks to extend tt_products.

// Hook for extending tt_products TCA
$TYPO3_CONF_VARS['EXTCONF'][TT_PRODUCTS_EXTkey]['extendingTCA'][] = 
MBI_PRODUCTS_CATEGORIES_EXTkey;

The TCA for the products categories will be changed with the categorie 
tree.
And you have where clauses which directly access the tt_products tables.

  if ($this->pid_list) {
	$SPaddWhere = ' AND tt_products_cat.pid IN (' . $this->pid_list . ')';
  }
Therefore this dependancy is needed to avaid SQL error messages.


And in the next version there will be a category mm table:
// Hook for extending the products list
require_once(PATH_BE_mbiproductscategories.'lib/class.tx_mbiproductscategories_category.php');
$GLOBALS['TYPO3_CONF_VARS']['EXTCONF'][TT_PRODUCTS_EXTkey]['prodCategory'][] 
= 'tx_mbiproductscategories_category';
