[JBoss Seam] - Extending EntityQuery and using ScopeType.SESSION question
by fernando_jmt
Hi.
I have extended EntityQuery and defining that component as SESSION scope. Then I defined a page action which will call the super.refresh() in order to clear the result data and execute the query every time the view is accessed (only one time because I'm using @Factory). But, the query is executed as expected the first time I enter the page, but then (when trying to show another page using the paginator) I always get exceptions saying "EntityManager is closed".
If I change the scope type to STATELESS, then it seems to work fine.
Is there some restriction regarding what scope to use with components extending EntityQuery object? or what am I doing wrong?
Any help will be appreciated.
Thanks in advance.
My source code is below:
Component class:
|
| @Name("userListing")
| @Scope(ScopeType.SESSION)
| public class UserList extends EntityQuery {
|
|
| @DataModel
| private List<User> usersResult;
|
| private UIData data;
|
| @Override
| public String getEjbql() {
| return "select u from User u";
| }
|
| @Override
| public String getOrder() {
| return "u.username desc";
| }
|
| @Override
| public Integer getMaxResults() {
| return 5;
| }
|
| public void reload() {
| super.refresh();
| usersResult = null;
| }
|
| @Factory(value = "usersResult")
| public void initialize() {
| int first = 1;
| if (data != null)
| first = data.getFirst();
| setFirstResult(first);
| usersResult = new PageList(getResultList(), getResultCount().intValue(), getMaxResults().intValue(), getFirstResult());
|
| //PageList is an extension to List which intends to be used by datatable and paginator.
| }
|
|
|
| public UIData getData() {
| return data;
| }
|
| public void setData(UIData data) {
| this.data = data;
| }
| }
|
|
|
pages.xml:
|
| <page view-id="/user/list.xhtml" action="#{userListing.reload}"/>
|
|
/user/list.xhtml:
| <rich:dataTable value="#{usersResult}" var="userItem" id="userListId"
| binding="#{userListing.data}"
| rows="#{userListing.maxResults}">
| ...//columns... and the Paginator.
|
| </rich:dataTable>
|
The exception stacktrace:
| GRAVE: Error Rendering View[/user/list.xhtml]

[JBoss Seam] - @DataModel does not create a component
by laksu
Hi,
I have a SFSB:
| /*
| package datassist.gop.action;
|
| import datassist.gop.domain.Istek;
| import datassist.gop.domain.Uzman;
| import java.io.Serializable;
| import java.util.List;
| import javax.ejb.Remove;
| import javax.ejb.Stateful;
| import javax.persistence.EntityManager;
| import javax.persistence.PersistenceContext;
| import javax.persistence.PersistenceContextType;
| import org.jboss.seam.ScopeType;
| import org.jboss.seam.annotations.Begin;
| import org.jboss.seam.annotations.Create;
| import org.jboss.seam.annotations.Destroy;
| import org.jboss.seam.annotations.End;
| import org.jboss.seam.annotations.Logger;
| import org.jboss.seam.annotations.Name;
| import org.jboss.seam.annotations.Scope;
| import org.jboss.seam.annotations.datamodel.DataModel;
| import org.jboss.seam.annotations.datamodel.DataModelSelection;
| import org.jboss.seam.log.Log;
|
| @Stateful
| @Name("isteklerAction")
| @Scope(ScopeType.SESSION)
| public class IsteklerAction implements Serializable, IsteklerActionLocal {
|
| @PersistenceContext(type=PersistenceContextType.EXTENDED)
| private EntityManager entityManager;
|
| public IsteklerAction() {
| }
|
| @Create
| public void init(){
| System.out.println("initing istekler. logger is "+((logger==null)?"null":"not null"));
| refresh();
| }
|
| @DataModel
| private List<Istek> isteklerList;
|
| public void refreshIstekler(){
| System.out.println("refreshing istekler");
| isteklerList=entityManager.createQuery("from Istek i").getResultList();
| for(Istek i:isteklerList){
| System.out.println("Istek: id="+i.getId()+" konu="+i.getKonu()+" acan="+i.getAcan().getAdSoyad());
| }
| }
|
| private List<Uzman> uzmanlar;
|
| private void refreshUzmanlar(){
| System.out.println("refreshing kullanicilar");
| uzmanlar=entityManager.createQuery("from Uzman u").getResultList();
| for(Uzman u:uzmanlar){
| System.out.println("Uzman: id="+u.getId()+" ad="+u.getAd());
| }
| }
|
| public void refresh() {
| refreshIstekler();
| refreshUzmanlar();
| }
|
| @DataModelSelection()
| private Istek istek;
|
| @Begin
| public void setIstek(Istek istek){
| System.out.println("Istek=");
| System.out.println("Istek: id="+istek.getId());
| System.out.println(" konu="+istek.getKonu());
| System.out.println(" acan="+istek.getAcan().getAdSoyad());
|
| this.istek=istek;
| entityManager.refresh(istek);
| }
|
| @Begin
| public void select(){
| System.out.println("Istek=");
| System.out.println("Istek: id="+istek.getId());
| System.out.println(" konu="+istek.getKonu());
| System.out.println(" acan="+istek.getAcan().getAdSoyad());
| }
|
| @End
| public void clear() {
| istek=null;
| }
|
| public List<Istek> getIsteklerList() {
| return isteklerList;
| }
|
| public void setIsteklerList(List<Istek> istekler) {
| this.isteklerList = istekler;
| }
|
| public List<Uzman> getUzmanlar() {
| return uzmanlar;
| }
|
| public void setUzmanlar(List<Uzman> uzmanlar) {
| this.uzmanlar = uzmanlar;
| }
|
| public void logSomething(){
| System.out.println("Trying to log something dummy and the logger is "+((logger==null)?"null":"not null"));
| }
|
| @Logger
| private Log logger;
|
| @Remove @Destroy
| public void destroy(){}
|
| }
|
and I have the following in my page:
|
| <h:dataTable var="istek" value="#{isteklerlist}">
| <h:column>
| <f:facet name="header">No</f:facet>
| <s:link value="#{istek.id}" action="#{isteklerAction.setIstek(istek)}"/>
| </h:column>
| <h:column>
| <f:facet name="header">Tarih</f:facet>
| #{istek.acilis}
| </h:column>
| <h:column>
| <f:facet name="header">Konu</f:facet>
| #{istek.konu}
| </h:column>
| </h:dataTable>
|
I cannot make the table to display the isteklerList. The table's header shows up but no data. I have verified to print that the data exists. I have a similar page in another app working but this one does not. In fact the DataModel component is not even created. I checked with the debug page to see that no component named "isteklerList" exists.
What am I missing?
