Seam Application Framework: In depth details !

[allforjava.allforjava.aol.in]

Hi,

Through 'Generate Seam Entities' Tasks.java, TaskList.java & TasksHome.java are generated along with the respective .xhtml & .page.xml.

1.I need to know how an instantion [of Task.java] is handled by _Home.java [EntityHome] and _List.java [EntityQuery].
2. Also whether there is any way [Home/List].java communicates on 'create'.
3. Along with the limitations and features of [Home/List].java

I'd read through [http://docs.jboss.com/seam/latest/reference/en-US/html/framework.html]. However the concept is not clarified.

[TODO]: For example: We want to select a value from listbox_1 [eg:Country] and accordingly load the values into listbox2 [eg: States] dynamically. These details are stored in tables with relation.

Thank you in advance.
