The method names need to match I was thinking it would work things out, but i guess that the indexed property name must match the method even when the object is scoped during the iteration.

Sure the method names were just an example rather than copy n pasting my code into a mail.
I'm not using the nested tags lib as I don't mind drilling through to nested objects. The form renders fine and i can set the values, its when i submit the form, i don't get the values that the user sets in the jsp, but rather those that are set in the action before forwarding to the form.
I've been getting n setting my indexed properties like you say. I've tried just using arraylist and not casting to an array.
Like i said i've a work around, but I dont like it as i need to match the name of the object thats scoped during the iteration.
I'm sure it should work because nesting beans is so useful. out of interest have you been able to do this?
Absolutely. I still tend to favor the nested tags for indexed and nested
properties. Are you sure the HTML for the form is really being rendered
correctly? Since you can access your data explicitly through
request.getParameter, it just seems like there's a mismatch between the rendered
parameter names and the properties exposed by the form.

<html:form ...> <nested:iterate property="beans"> <nested:text property="foo"/> <nested:iterate/> </html:form>
For the form class, the JavaBeans pattern for an indexed property is the following:
public void setter(int index, PropertyType value); public PropertyType getter(int index); public void setter(PropertyType[] values); public PropertyType[] getter();
For Struts, since it leverages BeanUtils, you can shorthand it to:
public void setter(List values); public List getter();
I'm not really sure you're exposing the properties you think you are because you're using inconsistent method names (getBeans and getBean) as well as property types (Object[], ArrayList, and NestedBean).

Has anyone else had any problems setting nested bean values
Here's and example of what i mean..
public class DemoForm extends ActionForm {
private ArrayList beanList;
public DemoForm() { this.beanList = new ArrayList(); }
public Object[] getBeans() { return beanList.toArray() } public void setBeans(ArrayList beanList) { this.beanList = beanList; } public NestedBean getBean(int i) { NestedBean bean = (NestedBean) beanList.get(i); return bean; } //and so on }
..
public class NestedBean { private String foo;
public String getFoo() { return foo; } public void setFoo(String foo) { this.foo = foo; } }
.. <c:forEach var="bean" items="${myForm.beans}"> <html:text name="bean" property="foo" indexed="true" /> </c:forEach>
The problem comes when i change values in the form element the values
dont change so i guess the jsp and the servlets aren't interacting. I
work around by retrieving form the parameter map
String target = "bean["+ i +"].foo"; String value = request.getParameter(target).toString();
This works okay , but I'd really like to know wether i can do this without this hack.
