Hi Walter first of all I propose to write the php like this:

<?php

if($this->isNotEmpty()) {
	$content='<ul>';
	for($this->rewind();
		$this->valid();
		$this->next()) {
			$content.='<li>';
			$this->printAsText( $this->current() );  ##
			$content.='</li>';
		}
	}
	$content .='</ul>';
	echo $content;
}

?>

It's a lot clearer to read and I think avoids some faults.

Concerning your problem have a look at line with the ## at the end.
I'm not sure, but $this->current() logically has no function printAsText().

Best regards
