Hello I have just made an tested an add on for your script for auto-complete feature with script.aculo.us. I wish only to give for some one that whant to use it

<?php

/**
* extend original FormHandler
*/

class FormHandlerExt extends FormHandler {

    /**
     * FormHandler::setAutoCompleteScriptaculous()
     *
     * Set Ajaxconnection  and field for autocomplete field
     *
     * @param string $field: The field which should be auto complete
     * @param array $options: The list of options for the uto complete
     * @return void
     * @access public
     * @author HonorÃ© Vasconcelos, based on original made by Teye Heimans
     */
    function setAutoCompleteScriptaculous( $field, $Link )
    {
        static $setJS = false;

        // check if the field exists and is a textfield
        if( !$this->fieldExists($field) || strtolower(get_class( $this->_fields[$field][1] )) != 'textfield')
        {
            trigger_error(
            'You have to declare the textfield first! '.
            'The field "'.$field.'" does not exists in the form!',
            E_USER_WARNING
            );

            return;
        }

        // check if the options are correct
        if( is_array( $Link ) )
        {
            trigger_error( 'You have to a link to ajax handler!', E_USER_WARNING );
            return;
        }


        // add the javascript file if not done yet
        if( !$setJS )
        {
            $setJS = true;
            $this->_setJS( FH_FHTML_DIR.'js/prototype.js', true );
            $this->_setJS( FH_FHTML_DIR.'js/scriptaculous.js', true );
        }

        // create the javascript object to handle Ajax transfer
        $js = "\n".'new Ajax.Autocompleter("'.$field.'", "'.$field.'_choices", "'.$Link.'", {paramName: "value"});'."\n";
        $this->_setJS($js, false, false);
        $this->_fields[$field][1]->_sExtraAfter .="\n<div id=\"".$field."_choices\" class=\"autocomplete\"></div>\n";

    }
}

?>

Hello honore vasconcelso, your extension looks good. Do you only have this one new function for autocompletion? I want to create an ajax extensioncalss to FH, too.
