-------------------------

    Attachment: HelloStruts.zip

Actually this is not a bug, I am adding this file because 

in my requirement the form element 

<input type="text" name="list[2].name" value="C"> - <BR>

will be dynamic say

<input type="text" name="list[2].name" value="C"> - <BR>
<input type="text" name="list[3].name" value="C"> - <BR>
<input type="text" name="list[4].name" value="C"> - <BR>

since the form object (ArrayLisy) which don't have the index 2,3,4 

i am getting this exception.

can any one help me ?

> I have an ActionForm that has a getter and setter for a Collection of Objects.  The jsp uses the logic:iterate tag to output the indexed nested properties.  Everything works fine until the session times out.  Then I get the following stack trace:
