Question for Freddy, which may be answered by the real code, but the
link on the TTS site is still 404
In the ActivateActionBean, there is code such as
User existingUser = Database.getUser(user.getUsername());
Which throws the expected null pointer exception because the variable
user has not been initialized.
Where should that happen?
On initial activation, has a User been put in the Session or
FlashRequest? Where does that happen, because I don't see that in my flow.
Thanks

Pat,
I'll take a stab at it. The form that hits the event handler probably
has a field like <s:text name="user.username"/>. Stripes would hit your
ActionBean and if user is null it would call the default no-arg
constructor for User and then call the setter for username as long as
the field wasn't left blank. I'm guessing that you're either leaving the
field blank or calling the event from somewhere other than the correct form.
Adding a
@ValidateNestedProperties([EMAIL PROTECTED](field="username",required=true,on="myEvent")})
to the user declaration in your ActionBean (changing myEvent to match
the event that is being called) should at least get rid of the NPE.
