[jira] Created: (STR-2989) NullPointerException on indexed

NullPointerException on indexed properties only on session timeout
------------------------------------------------------------------
Key: STR-2989
URL: http://issues.apache.org/struts/browse/STR-2989
Project: Struts 1
Issue Type: Bug
Components: Core
Affects Versions: 1.2.9
Environment: Windows XP, WebLogic 8.1
Reporter: Steve Klosterbuer
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:
java.lang.NullPointerException

Hi Paul,
It is session scope. But, I've also tried request scope, which had the same
results.

[jira] Commented: (STR-2989) NullPointerException on indexed

Posted by "Paul Benedict (JIRA)" <ji...@apache.org>.
[ http://issues.apache.org/struts/browse/STR-2989?page=comments#action_39132 ]
Paul Benedict commented on STR-2989:
------------------------------------
The logic tags throw a NPE when they reference a null object. This is not a bug. If you need graceful handling of null objects, use JSTL which can check when references are empty.
As for the arrays, I am pretty sure arrays are not allocated automatically. They return to null after a request or when the session expires. If the array has to be there, you need to instantiate it in your constructor.

----------------------------------------
I'm not sure that I follow. This occurs when I attempt to submit the form
after the session has expired. Before the Action class gets the request,
the collections within the ActionForm are not successfully populated and I
get the resulting NPE.

[jira] Updated: (STR-2989) NullPointerException on indexed
properties only on session timeout
Posted by "Jayaraj (JIRA)" <ji...@apache.org>.

Jayaraj updated STR-2989:
-------------------------
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 ?

----------------------------------------
Hi Guys,
Thanks for following up with this, but it's probably something we can close
out now. I've moved on to another employer and project, so I don't have
access to this code base any longer.
Thanks for your help.
