IndexedPropertyDescriptor has null readMethod/writeMethod

[Paul Stanton]

hi. i am trying use work with an indexed property in struts 1.1.
i have set up my form bean as follows:
----code----
public class WelcomeForm extends ActionForm
{
        List things = new ArrayList();
        public List getThings()
        {
                return things;
        }
        public void setThings(List things)
        {
                this.things = things;
        }
        public SampleBean getThings(int i)
        {
                return (SampleBean) things.get(i);
        }
        public void setThings(int i, SampleBean thing)
        {
                while (things.size() >= i)
                        things.add(new SampleBean());
                things.set(i, thing);
        }
}
----/code----
my form is populated and on the request when it gets to my jsp, which 
has the following lines somewhere in the body

----code----
<logic:iterate name="/WelcomeForm" property="things" id="thing" 
indexId="beanIndex"><%
	String colProp = "things[" + beanIndex.intValue() + "].color";
	String foodProp = "things[" + beanIndex.intValue() + "].food";
	String numProp = "things[" + beanIndex.intValue() + "].number";%>
<tr>
	<td>color:<html:text property="<%= colProp %>"/></td>
	<td>food:<html:text property="<%= foodProp %>"/></td>
	<td>number:<html:text property="<%= numProp %>"/></td></tr>
</logic:iterate>
----/code----

this looks fine to me and i'm sure i've done it before.. anyway, when 
run i get: "javax.servlet.jsp.JspException: No getter method for 
property things of bean /WelcomeForm"

from breakpointing etc i have identified the problem: an 
IndexedPropertyDescriptor is created for the 'things' property, however 
the 'readMethod' and 'writeMethod' fields are null. i would expect the 
IndexedPropertyDescriptor to find my indexed methods and my non-indexed 
methods.. why is this happening?

thanks.
