Subject Strange behavior: Trying to implement saveToken() in display actions.
Date Tue, 01 Apr 2008 18:02:39 GMT
I am trying to implement a pattern so that I can use struts tokens to
help prevent double submission.  I seem to be getting a strange
sequence of events that I don't quite follow.  Here is what I want to
do at a high level

displayCreateAccount  -- forwards to -->  CreateAccount.jsp (with form
action defined as /createAccount)
createAccount -- forwards to --> displayCreateAccountStep2 -- forwards
to --> CreateAccountStep2.jsp

The actions that start with 'display' merely set the struts token (e.g
saveToken( request ); )
Then it forwards it along to a jsp.

The actions that start with 'Create' check to see if the token is
valid then it processes the form submission and then
forwards it to another display action which will then set the next
toke for the next display of a JSP.

I have checked and rechecked all of my configs but I do not see a
mistake.  I have also rebuilt the entire war
and cleaned out EVERYTHING in Tomcat but I get the same result.  When
I hit the first displayCreateAccount action
it properly forwards control to the jsp page that is then presented.
When the form on the jsp page is submitted
the displayCreateAccountStep2 action is found (see log below) in the
mapping YET the original displayCreateAccount is executed.  I have
turned on
debug of org.apache.struts.  Here is my struts-config.xml and a
snippet of the logs showing what is happening.

I am curious as to why this is happening.  I really want to understand
what I am doing wrong or why it is working this way.
Please let me know if I need to supply any more supporting documents.

thanks

Doug
