[TYPO3] TS Help: how to get the title of the current page's parent into a TEXT cObj?

[Ricardo Scachetti Pereira]

    Hi all,

    I need to get the title field (or nav_title) of the parent of the 
current page into a TEXT cObj. Can anyone help me write the TypoScript 
that does that? Thanks!!

    The following gives me the title of the current page into a TEXT cObj:

page.10 = TEXT
page.10 {
    field = nav_title // title
    wrap = <h2> | </h2>
}

    How do I get the title of the parent? Thanks.

Ricardo
