I am not sure if this has been identified or addressed in 2.2 ... placing in 2.0
as a tracking bug so we don't lose it.

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()
   {
       parent::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
$_SESSION['gszTmpPath'].session_id().".dbf"
           {
               unlink($oLayer->data.".dbf");
           }

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

               $_SESSION["gszCurrentState"] = $this->moMapObject->saveState();
           }
                 }
             // return success
       return true;
   }
