[JBoss Seam] - Exception: No session or session closed
by damatrix
I'm using JBoss 4.2.1.GA and Seam 2.0 CR1. I have an SFSB as follows
| */
| @Stateful
| @Name(value = "fairListing")
| @Scope(ScopeType.SESSION)
| public class FairListBean implements FairListLocal {
|
| @In
| EntityManager entityManager;
|
| @In
| FacesMessages facesMessages;
|
| @DataModel
| private List<FairDTO> fairs;
|
| @DataModelSelection("fairs")
| private FairDTO fair;
|
| @Factory("fairs")
| public void list(){
| fairs = new FairQM(entityManager).findAll();
| }
|
| public void showDetails(){
| this.fair = entityManager.merge(fair);
| }
| }
|
I'm using this to manage a Master-Detail page showing a dataTable of fairs. when a fair is selected, the showDetails() action is called and the details of a fair are shown below the dataTable using an <a:outputPanel>.
I read that using the ManagedPersistenceContext configured in components.xml and injected in your code does not throw LazyInitializationException (hope i got that right :-) ). I was quite surprised to find this exception being thrown.
Can anyone point out what i'm doing wrong?

[JBoss Seam] - Problems with HtmlSelectOneListBox and EntityConverter added
by Neiti01
Hi,
I try to add a SelectOneListbox, which uses the Seam EntityConverter, dynamically in a method of a EJB-Stateful-Session-Bean with the following code:
HtmlSelectOneListbox headerHersteller2 = new HtmlSelectOneListbox();
| headerHersteller2.setId("edit_headerHersteller2");
| headerHersteller2.setSize(5);
| HtmlSelectItems headerFirmenItems = new HtmlSelectItems();
| ValueBinding vb = context.getApplication().createValueBinding("#{logins.firmenItems}");
| headerFirmenItems.setValueBinding("value", vb);
| headerFirmenItems.setVar("firma");
| headerFirmenItems.setValueBinding("label", context.getApplication().createValueBinding("#{firma.namen}"));
| headerHersteller2.getChildren().add(headerFirmenItems);
| headerHersteller2.setConverter(context.getApplication().createConverter("org.jboss.seam.ui.EntityConverter"));
| headerHersteller2.setValueBinding("value", context.getApplication().createValueBinding("#{logins.umgebung.solution.firma}"));
|
The SelectOneListbox is added with the items as expected but there is no option preselected even tough the corresponding value for the ValueBinding #{logins.umgebung.solution.firma} is containing an object.
I read through the FAQ of the Entity-Converter and marked the method adding the Listboxm with the @Begin-Annotation to ensure Seam is in a long-running conversation.
Is there another setter i need to call on either the HtmlSelectOneListBox or the HtmlSelectItems (maybe the setValue()) ?
I am using JBoss-4.2.1.GA and Seam-2.0.0.CR1.
Thanks in advance.
Regards
Markus Neubrand
