Digging through the docs and the Templavoila code, I found the following
function:

    /**
     * Common function for rendering of the Flexible Content / Page
Templates.
     * For Page Templates the input row may be manipulated to contain
the proper reference to a data structure (pages can have those inherited
which content elements cannot).
     *
     * @param    array        Current data record, either a tt_content
element or page record.
     * @param    string        Table name, either "pages" or "tt_content".
     * @return    string        HTML output.
     */
    function renderElement($row,$table)    {
        // ...
    }
 
I assume this is the one I have to use to render a Flexible CE. But when
I try to use it, I get this error:

Fatal error: Call to a member function editIcons() on a non-object in
/var/www/onlinetaz/typo3_src-4.0.5/typo3/sysext/cms/tslib/class.tslib_pibase.php
on line 910

I have tried to access the function in this way:

    $FCE_Renderer = t3lib_div::makeInstance('tx_templavoila_pi1');
    return $FCE_Renderer->renderElement($ce, 'tt_content');

What am I doing wrong?
