</code>
if ( count( $nodeListArray ) > 0 )
</code>

we somehow made it that nodelistarray was FALSE and a count on FALSE returns 1. it was joining the if clause even if nodelistarray was FALSE.

additional you can add a check for the existance of the variable?

patch could look like this:

if ( is_array($nodeListArray) && count( $nodeListArray ) > 0 )
or
if ( $nodeListArray and count( $nodeListArray ) > 0 )

Steps to reproduce

<?php
$testArr = FALSE;
echo count($testArr);
?>

Will output: 1
