I found that in chameleon-2.0 the widget ClearPoints doesn't work.

here the corrections that make it works for me:

I change the PerseURL function....

 function  ParseURL()

        if ($this->isVarSet("CLEAR_POINTS") &&
            $this->getVar("CLEAR_POINTS") == "1")
            $oMap = $this->moMapObject->oMap;
            $oLayer = @$oMap->getlayerbyname("MapNotesAnnotation"); 
//doesn't work with "cwc_tmp_point"

            // First step, clearr all point from shape file
            if (file_exists($oLayer->data.".dbf")) //doesn't work with 

            // Then, clear point layer from current map file
            if ($oLayer !== false)
                $oLayer->set("status", MS_DELETE);

                $_SESSION["gszCurrentState"] = 
        // return success
        return true;
