had a similar issue and found this thread, but then I figured it out, if you haven't here it is.

I originally added my new field right under the declaration of the validfields like so:

PHP Code:

    var $validfields = array();
    $this->validfields['MYVAR'] = array(TYPE_INT, REQ_NO); 


But then, duh, I realized, this is a class. You can't do random operations outside of functions and stuff, so if you move that to a function it works. I moved mine into

PHP Code:

function vB_DataManager(&$registry, $errtype = ERRTYPE_STANDARD) 


So it looks something like so:

PHP Code:

    function vB_DataManager(&$registry, $errtype = ERRTYPE_STANDARD)
    {
        if (!is_subclass_of($this, 'vB_DataManager'))
        {
            trigger_error("Direct Instantiation of vB_DataManager class prohibited.", E_USER_ERROR);
        }

        $this->validfields['MYVAR'] = array(TYPE_INT, REQ_NO);
///...rest of function
