STRUTS: Tags inside innerHTML

Hi!

I seem to be having problems using struts tags inside an innerHTML. The design of the page (in this case, it's a popup) is that I have a dropdown (let's say it's DropDown1 for now) box and beside it will be either a textbox or another dropdown(let's call this DropDown2 for now) box (depending on the value selected on DropDown1, it will either show a textbox of DropDown2). All the values for the dropDown boxes are taken from a db and stored in a collection(in my action for initializing the popup). I decided to use innerHTML for this one, but I seem to always get an error with the javascript code I have below. If I don't use struts tags (I tried it out with the regular html tags just to see test) it works fine...any help would be greatly appreciated. =)

I have the following declaration on my page:

<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>

Here's my javascript function:

function changeField()
{
      var value = document.advanceFilterForm.field.selectedIndex.value;
      
      if ( value == "Release Dates")
      {
            
          document.getElementById( 'valuediv' ).innerHTML =  '<html:select property="value" style="width:116px"><html:options collection="values" property="value" labelProperty="description" /> <html:select>'
      }
      
      else
      {
          document.getElementById( 'valuediv' ).innerHTML = '<html:text property="value" style="width:200px" />'
      }
}

</script>

Here's the error:

org.apache.jasper.JasperException: Cannot find bean under name org.apache.struts.taglib.html.BEAN

Using struts tags implies that you have an object holding the values in your form.  As you do not specifyc a name attribute on the struts tags, struts searches for a bean with the key 'org.apache.struts.taglib.html.BEAN' in page, request, session, application scope (in that order.)

As you haven't set one up, the obvious question is, why are you using struts tags for this?
