[JBoss Seam] - Re: @Out-jection fails to work in certain conditions - Bewar
by gothmog
Hi Norman,
Yes I can confirm that by simply changing the scope to SESSION and removing the @Begin does make the example work.
I also tried the @Out(required=false) Item and changed the page to read the @Out-jected item instead of the action class getter and left the scope as CONVERSATION. I got the following:
1. The @Create annotation method did fire, makes sense as there is now no reference to the testPage class in the rendering as all reference is to the out-jected item variable.
2. The example works, albeit slightly differently as item is null to begin with until you press the New Item link, but otherwise everything works as expected.
If I force the @Create to run by inserting a dummy #{testPage.item} into the page, leave the scope as CONVERSATION the example goes back to not working.
If I use @Factory("item") instead of create the example fails. (Scope is still CONVERSATION)
If I change the scope to SESSION and use @Factory("item") the example fails
If I change the scope to SESSION and use @Create (with and without forcing the @Create method to run) the example works!
Hope this helps, its sure baffling me. It seems curious combinations of @Create @Factory and session scope are causing the failure
As an aside does anyone know why jboss 4.2 keeps running out of PermGen Space on deployment?
I am using:
Seam 2.0.0BETA
RichFaces 3.1.0
Jboss 4.2.GA

[Installation, Configuration & DEPLOYMENT] - nullpointer at DatabasePersistencePolicy.listTimerHandles
by hejulrik
Hi!
When I deploy my application in Jboss4.0.5GA ( clustered) I get nullpointer exception at org.jboss.ejb.txtimer.DatabasePersistencePolicy.listTimerHandles ........
.....
Is it some database-connection problem or some configuration error ?
I've succed to deploy it when running non-clustered Jboss4.0.5.
Here is the stacktrace:
Problem starting service jboss.j2ee:ear=ebill-ear-1.0-SNAPSHOT.ear,jar=ebill-engine-1.0-SNAPSHOT.jar,name=DefaultExternalInvoiceSystemBrokerBean,service=EJB3

[JBoss Seam] - getter problem
by skanky78
hi,
my problem is a well known problem but nonetheless i'm wondering how to do it right..maybe one of you can help me with this issue:
i have a datatable which uses an extended datamodel (similar to this example http://wiki.apache.org/myfaces/WorkingWithLargeTables) to cope with large amount of data. the problem is that @datamodel doesn't work with that kind of object so i need another way how to avoid that my buisness logic (database calls) in the getter are executed several times per request.
class:
@Scope(ScopeType.SESSION)
| @Name("component")
| public class Component {
|
| public getDataModel() {
| // calls to database etc.
| }
|
| }
xhtml:
anonymous wrote :
| <rich:datatable id="dataTable" value="#{component.dataModel}" var="product" >
|
| ...
|
| </h:datatable>
the data of the table should be refreshed with every request, for example if the user hits the refresh button of the browser. how can i remove my buisness logic from the getter? is there a way to use @factory (and @datamodel)?
thanks in advance,
sven
ps: i'm not using hibernate...
