[jboss-user] [JBoss Seam] - How does the DataModel passes the data to the next page?

Hi all, I try to understand the Issue-Tracker example, and hope that someone could explain me a little bit more about the page and object flow. Esspecially I'm interested how the DataModel / dataTable works, because I need this in an application Therefore I took the ProjectFinderBean, ProjectSelectorBean and ProjectEditorBean and extended them with some debug messages. So I could figured out the dependencies between this 3 classes, if I click on one of the "View"-button: | Caller: ProjectFinder #1 | - (Create) | JSF(@Factory) -------------> findProjects | ProjectSelector #1 | JSF ----------------------------------------------> (Create) ProjectEditor #1 | @In ---------------------------> (Create) | JSF ----------------------------------------------> getButtonLabl (x-times) | JSF ----------------------------------------------> isCreateEnabled (x-times) | EndOfRequest (1) destroy | EndOfRequest (2) getIssueList | EndOfRequest (3) destroy | ProjectEditor #2 | "View"-button (4) @In --------------------------> (Create) | ProjectFinder #2 | (5) (Create) <---------------- @In | isCreateEnabled (x-times) | select | (6) getSelection <------------ | ------------------------------> setInstance | JSF getIssueList | . | . | . | The number in the brackets are the points which are not really clear to me. So here (maybe some newbie) questions: (1) and (3): Does the tranisient keyword destroies the instances or the end of the request? Or both? (2): Why is getIssueList() is called after destorying the ProjectEditorBean? (4) and (5): Why is the @In is called after clicking on the "View"-button? Because of (1) and (3) ? (6): How does the new instance of the ProjectFinderBean know which list entry was selected? Does this the PAGE-Scope on the @DataModel? And one last question: Why do I need session beans to pass the selected entry to another bean? Or is there a solution to do that with 2 beans.
