Srinivas,
This has come up a little while ago and I've added to the nested
extension to allow for it. The problem is, is that if you have other
nested tags inside an iterate tag or similar, they will work on a
property returned from that object from the list etc. What was needed
was to access the object itself. This was just not possible in the
original tags or otherwise.
To allow this I've added the ability to access the current object from a
parent. Using "./" or "this/" as the child tag's property, you will
access the parent object itself. So if it's a string, you can write it
out, make it an input field etc.
For example...
<nested:iterate property="stringList">
<nested:text property="this/" />
</nested:iterate>
...will loop through an array of Strings and make text inputs for them.
There is one specific detail to get this working properly. In your bean,
you have to provide the more literal form of indexed setter property,
rather than the collection form used for the getter.
Example where I'm setting the value back to my ArrayList...
public void setStringList(int index, String str) {
myList.set(index, str);
}
My getter remains unchanged as the collection form...
public ArrayList getStringList() {
return myList;
}
This is all because the system which sets it wont be pulling out the
collection, making the modifications, and then returning it altered. It
will leave everything up to you. This is still good however.
This functionality is in the nightly build from the 23rd of Jan, or you
can download an updated jar from the site.

As a small disclaimer, the ArrayList getter shown above is only possible
with a nightly build. Users of Struts 1.0/1.01 will need to return an
Object array as in "arrayList.toArray()".
Hope this does what you're after.
Arron.
