[JBoss-user] [JBoss Seam] - Re: How do I reattach entities using a ManagedHibernateSessi
Yes, sorry I neglected to mention that. Here is the relevant code:
@Stateful
| @Scope(ScopeType.CONVERSATION)
| @Name(campaignEditor)
| public class CampaignEditorBean implements CampaignEditor {
|
| @Valid @In(required=false) @Out
| private Campaign campaign;
|
| @In(create=true)
| private Session session;
|
| @Begin(join=true)
| public String select() {...
|
| @End
| public String update() {...
| ...
|
| @Entity
| @Name(campaign)
| @Scope(ScopeType.SESSION)
| public class Campaign {
| ...
|
In my view, I reference properties on campaign. Whenever I try to reference
any property that is lazily initialized, I get the LazyInitializationException
unless I first manually call
sessionFactory.getCurrentSession().update(campaign).

The problem is the ScopeType.SESSION bit. This functionality is only for conversation-scoped data.

[JBoss-user] [JBoss Seam] - Re: How do I reattach entities using a ManagedHibernateSessi
Thanks for the reply. I modified the entity as follows:
@Entity
| @Name(campaign)
| @Scope(ScopeType.CONVERSATION)
| public class Campaign {
| ...
|
However, I still have the same problem. Here is the debug output from Seam
where it looks like it's resolving campaign:
2006-06-30 16:34:08,471 DEBUG [org.jboss.seam.jsf.SeamVariableResolver]
resolving name: campaign
| 2006-06-30 16:34:08,471 DEBUG [org.jboss.seam.contexts.Contexts] found in
conversation context: campaign
| 2006-06-30 16:34:08,471 DEBUG [org.apache.myfaces.el.VariableResolverImpl]
Variable 'campaign' could not be resolved.
| 2006-06-30 16:34:08,471 DEBUG [org.jboss.seam.jsf.SeamVariableResolver]
resolved name to seam component
|
Any other suggestions?

Did you actually retrieve the Campaign from the conversational persistence context? Or is it some other object you had lying around before the conversation started? It is really not helpful when you chop out the actually intersting code in select() and update().

[JBoss-user] [JBoss Seam] - Re: How do I reattach entities using a ManagedHibernateSessi
Sorry. The Campaign came from another SFSB (CampaignManager), where it came
from a list using @DataModelSelection. Here's the code without the omissions:
@Stateful
| @Scope(ScopeType.CONVERSATION)
| @Name(campaignEditor)
| public class CampaignEditorBean implements CampaignEditor {
|
| @In
| private CampaignManager campaignManager;
|
| @Valid @In(required=false) @Out
| private Campaign campaign;
|
| @In(create=true)
| private Session session;
|
| @Begin(join=true)
| public String select() {
| campaign = campaignManager.getSelectedCampaign();
| return editCampaign;
| }
|
| @End
| public String update() {
| session.update(campaign);
| return campaigns;
| }
| }
|
| @Stateful
| @Scope(ScopeType.SESSION)
| @Name(campaignManager)
| public class CampaignManagerBean implements CampaignManager {
|
| @DataModel
| private ListCampaign campaigns;
|
| @DataModelSelection
| private Campaign campaign;
|
| public Campaign getSelectedCampaign() {
| return campaign;
| }
| }
So yes, I guess you could say the Campaign was lying around before the
campaign started. Is there any way that I can use the @DataModelSelection
campaign in the conversation, so I can get around the
LazyInitializationExceptions?

Thats what I guessed. So you need to do:
| @Begin(join=true)
| public String select() {
| campaign = session.lock( campaignManager.getSelectedCampaign(),
LockMode.NONE );
| return editCampaign;
| }
|
In order to get a Campaign that is associated with the conversation. After
doing this once at the beginning of the conversation, you will not need to do
it again.

I spoke a little too soon. The second time that I try to invoke CampaignEditorBean.select on the same campaign, I get a reassociated object has dirty collection HibernateException from the session.lock call.
