Hi all,
I cannot make the examples in chapter 11 working:
http://docs.jboss.com/seam/2.0.0.B1/reference/en/html/framework.html
I've started with Person and PersonHome, with the creation button only. And
worked up to that point.
Then I've added update and delete, and I've added a query object, so that I can
have an access point to the edit page.
What I get is: 1) Creation still works 2) when I select some item to be updated
and I submit the edit form anything is updated. If I click on delete, anything
is deleted either 3) After having clicked on update or delete, I am bring back
to the creation page (with Create button only)
I've tried to extend update() in PersonHome, to add a logging message, and I
may see the method is not called at all, same for delete. I also have tried to
add a foo() action to the home, and this isn't called either.
Please find the code below. I am afraid I am missing something important.
Thanks in advance for any help.
Cheers.
Marco.

Also I have the parameter specification in pages.xml:

And the query spec in components.xml:
| <framework:entity-query name="people" ejbql="select p from Person p"/>
