Have you tried the nested tags on this?
<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).
