Hello,
In Chapter 6 of "Practical Apache Struts 2 Web 2.0 Projects", It explains how
to use the scope interceptor to create sort of wizard pages.
I've been trying to figure these out, but cannot get this to work.
Even the included example (downloadable from
http://www.apress.com/book/view/1590599039 ) do not work for me.
I was hoping someone could try them and tell me if they are indeed broken or if
i am doing something wrong. And what that might be?
Running the examples with no changes and when going to the second step in the
workflow I get the following error:
HTTP ERROR: 500
Error setting expression 'model' with value '[EMAIL PROTECTED]'
RequestURI=/app/event/selectLocation!input.action

Can provide full stack trace if needed
The following is also outputted from the example.
