Limiting the size of xforms:textarea

Hi,

 Is it ok to limit the size of a text area like this? (since xxforms:size
does not work on textareas)?


     <script language="javascript" type="text/javascript">
       var textarea1 = document.getElementById("PREFERED_CALL_TIME");
       textarea1.onkeydown=function () {
               var val =  ORBEON.xforms.Document.getValue("PREFERED_CALL_TIME");
               if(val.length &gt;= 10)
                       ORBEON.xforms.Document.setValue("PREFERED_CALL_TIME",
val.substring(0,9));
               };
     </script>



Is there a better way? Are there any unexpected by-products of this
approach?

Thanks

Nicolas

Will the addition of the incremental attribute result in a server call
on every keystroke?

Thanks
