keeping result of datatable

ajanz Jul 28, 2009 11:47 PM

i got an ear deployed app wiht a query page with a rich:datatable.

i want to keep the result list of the table, so every time the user comes back he will see his last result.

first i implemented the bean with result with @Scope(ScopeTye.SESSION)

but i think this is the wrong way....

so i tried using @Stateful, but every time the page renders the result is newly created.

any tips what i am doing wrong?

Use conversation scope for you backing bean (typically JavaBean or SFSB).

Use @Begin(join=true) on your action method (or when the page loads in pages.xml) to start a LRC (long-running conversation). In Seam, there is always a temporary conversation but if it is not promoted to a LRC then the component will be destroyed by Seam.

You can test this by adding the following code and a debug brkpt in your IDE:

@Destroy public void destroy() { log.info("in destroy"); //<-- brkpt here! }

Before and after you after you add the @Begin(join=true) annotation.

You will likely need an @End as well on your submit method or equivalent.

Read the Seam ref doc, this is basic conversation mgmt stuff...
