Examples about Application Framework (Chapter 11)

[zakmck]

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:

 <page view-id="/person.xhtml">

 </page>

And the query spec in components.xml:

<framework:entity-query name="people" ejbql="select p from Person p"/>
