I have the following zk page

<?page title="new page title" contentType="text/html;charset=UTF-8"?>
<zk>
    <window id="id_without_spaces" title="old title" border="normal">
        <zscript><![CDATA[
                     id_without_spaces.setTitle("new title"); // works fine
        ]]></zscript>
    </window>
    <window id="id with spaces" title="old title" border="normal">
        <zscript><![CDATA[
                     id with spaces.setTitle("new title"); // how to reference?
        ]]></zscript>
    </window>
</zk>
