TYPO3 Core

Unsetting Stopwords in Info->Indexed Search [Detail Page View] is not possible.

If you just set one Word, save, uncheck and save again you will get this message:
"Invalid argument supplied for foreach() in /var/www/www/kbgk/2009/data/typo3/sysext/indexed_search/modfunc1/class.tx_indexedsearch_modfunc1.php on line 1345"

If you set and unset more words you doenst get any error, but every unchecked word is still checked.

A little Workaround for function processStopWords:

/**
     * Setting / Unsetting stopwords
     *
     * @param    array        Array of stop-words WIDs with 0/1 to set / unset
     * @return    void
     */
    function processStopWords($stopWords, $phash)    {

        if ($GLOBALS['BE_USER']->isAdmin())    {
                // Traverse words

            // Finding all words for this phash:
            $ftrows = $GLOBALS['TYPO3_DB']->exec_SELECTgetRows(
                        'index_words.*, index_rel.*',
                        'index_rel, index_words',
                        'index_rel.phash = '.intval($phash).
                            ' AND index_words.wid = index_rel.wid',
                        '',
                        'index_words.baseword',
                        ''
                    );
            foreach ($ftrows as $_ftrow_num => $_ftrow)
            {
                if ((int)$stopWords[$_ftrow['wid']] != $_ftrow['is_stopword'])
                {
                    $changed_stopwords[] = array('is_stopword' => (int)$stopWords[$_ftrow['wid']], 'wid' => $_ftrow['wid']);
                }
            }

            foreach ($changed_stopwords as $_stopwords)
            {
                $fieldArray = array(
                    'is_stopword' => $_stopwords['is_stopword'],
                );
                $GLOBALS['TYPO3_DB']->exec_UPDATEquery('index_words', 'wid=' . $_stopwords['wid'], $fieldArray);
            }
        }
    }

Are Stopwords allready in use, or is it not implemented yet?

(sorry for bad english).
