[TYPO3-project-formidable] renderlet:BUTTON: Do something if clicked without JS

[Hauke Hain]

Hi,

at the moment I use this:
<renderlet:BUTTON name="delete" label="LLL:be.delete">
          <onclick>
            <userobj>
              <php><![CDATA[
                $aRow = t3lib_div::_GP('tx_preview');
                $GLOBALS["TYPO3_DB"]->exec_UPDATEquery(
                    "fe_user",
                    "uid='" . $aRow['uid'] . "'",
                    array("deleted" => '1')
                 );
              ]]></php>
            </userobj>
          </onclick>
    </renderlet:BUTTON>

Now I want the same functionality realised in another way. Is there one in 
formidable?
I would prefer a way without JavaScript.

One reason I am looking for another possibility is this bug (see the third 
note (0027693)): http://bugs.typo3.org/view.php?id=10631

Kind regards,
Hauke
