The level parameter in an attribute(show,4) for ex is not working.
This is because in eztemplateattributeoperator.php on line 115 the last paramter "$txt" is wrong.
$this->displayVariable( $item, $formatter, $showValues, $max, $level + 1, $txt );
It must be changed to "$outputString" to make the level paramter working.
$this->displayVariable( $item, $formatter, $showValues, $max, $level + 1, $outputString );
