Radek Mensik commented on STR-899:
----------------------------------

My solution, how to fix SAME NAMES IN ALL FORMS connected with same ACTION is : if the name of form is wrong, just try all forms, if they containt the element you wanna update.
Example : Replace this
function showCalendar(year, month, day, pattern, formName, formProperty, event, startYear, endYear) {
  
  
  if (document.forms[formName].elements[formProperty].disabled) {
			return;
	}

and fill the while cycle to find correct form

function showCalendar(year, month, day, pattern, formName, formProperty, event, startYear, endYear) {
	i=1
  while(document.forms[formName].elements[formProperty]==null&&i<20){
  formName=i;r
  i++;
  }
  
  if (document.forms[formName].elements[formProperty].disabled) {
			return;
	}

> If you have a JSP with 2 forms of the same name (action) - the javascript 
> rendered results in a javascript error.
> To solve - change this:
> <script language="JavaScript" type="text/javascript">
>   <!--
>  if (document.forms["uploadFiles"].elements["uploadedFile"].type != "hidden") 
>     document.forms["uploadFiles"].elements["uploadedFile"].focus()
>   // -->
> </script>
> To something like:
> <script language="JavaScript" type="text/javascript">
>   <!--
>  if (document.forms[1].elements["uploadedFile"].type != "hidden") 
>     document.forms[1].elements["uploadedFile"].focus()
>   // -->
> </script>
> So you'd have to know the number of forms on the page.  Also, the 
> language="Javascript" is not needed (it's invalid for XHTML), just the type.
