Hello, I try to update the relations between tt_news and tt_news_cat using the TCE. $this->tce->start($data, array()); $this->tce->process_datamap(); tt_news_cat_mm is a typical T3 MM-Table, but somehow I can't figure out, how to apply TCE for this standard case. It's not coverd by the Core API. Thank you for any hints Elmar
