I just googled "needsReloading(FileManager.java:209)" and found [1] :)
it seems has been a bug and has fixed in 2.1.8.

Please create a GitHub repo with your code and I'll take a look. Note that
the examples from the book were tested only on Tomcat, and a pretty long
time ago. I'll need any server details you're using.
Also note that S2 is fairly different now than when the book was written.

StrutsSpringTestCase extends StrutsTestCase which extends another class that
depends on JUnit 3 not JUnit 4.
So you cannot use JUnit 4 annotations and the SpringJUnit4ClassRunner.

1. Yes. The LoginAction is annotated with @Namespace("/login"), and
the register() action is annotated with @Action(value="register").
2. I'm not sure what you're saying. Since StrutsTestCase initializes
this to a new object, why do I need to check for null?

Hi Musachy,
Thanks for the reply. I debugged and just found that the select tag could
not render "children[i]" as a list element.As I mentioned before if I change
children[i] to children(i), just to try whats happening, the page loads
fine.
Since we work on Agile and had a deadline of an hr or so,
can you debug it and see what is actually null? It seems like a bug.
That being said, I am building 2.1.8 as we speak, so if you are
planning to upgrade, it might be worth waiting a bit.

The two lines I think you want to validate first are:
String sqlQuery = ((ExecuteQueryForm) form).getSQLQuery();
and
session.setAttribute("query",form);
Since they are not within your catch, they could cause problems. If your form
is null, as someone else said, you'd be in trouble.

Hi,

get this error. However, I noticed that in your action
mapping in struts-config.xml,
you do not specify the complete path for your input
