TYPO3 Core

I just tried typo3 4.4.0 and the problem doesn't exist in this release. The problem is only present in 4.4.1.

Please test the SVN TYPO3_4-4 branch or test the upcoming TYPO3 4.4.2 release - the behaviour your reported is fixed there...

I can confirm this bug. Same problem in Typo 4.4.2 release.

I fixed the bug in Typo 4.4.2 by changing the function getIcon in class.t3lib_treeview.php (line 655 ff) as follows:

function getIcon($row) {
        if ($this->iconPath && $this->iconName) {
            $icon = '<img'.t3lib_iconWorks::skinImg('',$this->iconPath.$this->iconName,'width="18" height="16"').' alt=""'.($this->showDefaultTitleAttribute ? ' title="UID: '.$row['uid'].'"':'').' />';
        } else {
            $icon = '';
            if (is_array($row)) {
            $icon = t3lib_iconWorks::getSpriteIconForRecord($this->table, $row, array(
                'title' => ($this->showDefaultTitleAttribute ? 'UID: ' . $row['uid'] : $this->getTitleAttrib($row)),
                'class' => 'c-recIcon'
            ));
            }
        }

return $this->wrapIcon($icon,$row);
    }
--------------------------------

Don´t know about possible side-effects yet.

One more hint to the background of the described problem: It seem to have a relation to the extension tt_news. It occurs when an older version of tt_news (2.x) was installed before.

Yes, as Maik said, the problem occurs only, if an older tt_news plugin was installed. I upgraded to typo3 4.4.2 an tt_news 3.0.1, but it doesn't help.

I just tried typo3 4.4.4. It is still the same problem.

I applied the patch from Maik Matthis and it helped to solve the problem.
Hope this patch will be included in future releases.
