Conversation - setting and getting

[urosmil]

Hi,

I have 2 questions:

1) is it possible to set conversation scope in faces-config.xml; in the same way as for session scope:

<managed-bean-scope>session</managed-bean-scope>

2) how go get conversation scoped bean through java code, as it's possible for session scoped bean:

MyBean myBean = (MyBean) FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("myBean" );

Thanks,
Uros!

No. And a bean declared in faces-config.xml isn't a Seam component.

2) how go get conversation scoped bean through java code, as it's possible for session scoped bean:

Contexts.lookupInStatefulContexts("foo")

or

Contexts.getConversationContext().get("foo")

Hi petemuir,

both "Contexts.lookupInStatefulContexts("myBean")" and "Contexts.getConversationContext().get("myBean")" return null when I try to get conversation bean in session scoped bean.

I open pop-up window from conversation bean (offerBean). That pop-up use other session scoped bean (offerPreviewBean). Inside offerPreviewBean I try to access offerBean and I got null.

Is there some conditions in which code you post doesn't work?

Thanks,
Uros!

Are you propagating the conversation to the popped up window?

[urosmil]

Hi petemuir,

pop-up is not in conversation. I don't it should be inside conversation. Pop-up use other session scoped bean.
Am I making mistake in use?
In what situations is possible to access conversation scoped bean?

Thanks,
Uros!

Hi,

I will explain my problem hopping someone can help:

From page which is in conversation I open pop-up window with url: offer.jsf?lang=en&id=173&type=offerId. Page offer.jsf use session (doesn't need to be session; can be request to) scoped bean "offerPreviewBean". In "offerPreviewBean" bean I try to access conversation scoped bean "offerBean".

Is this possible and if it isn't how to solve this problem?

I can explicitly add objects I need in session but if I use that practice I'm moving back to JSP world.

Thanks,
Uros!

Ok, fair does. Can you post the content of the popup window and any beans you call off it (offerPreviewBean, offerBean).

Hi petemuir,

this is link:

offer.jsf?lang=en&id=173&type=offerId

this is pages.xml part:

<page view-id="/offer.xhtml">
 <param name="lang" value="#{offerPreviewBean.lang}"/>
 <param name="id" value="#{offerPreviewBean.id}"
 converterId="javax.faces.Integer"/>
 <param name="type" value="#{offerPreviewBean.offerIdType}"/>
 <action execute="#{offerPreviewBean.setOffer}"/>
</page>

this is OfferBean:

@Name("offerBean")
@Scope(ScopeType.CONVERSATION)
@Conversational(ifNotBegunOutcome = "offerBook")
public class OfferBean extends BaseBean{
 // ...
}

this is OfferPreviewBean:

@Name("offerPreviewBean")
@Scope(ScopeType.SESSION) //ScopeType.EVENT
public class OfferPreviewBean extends BaseBean{
 public OfferPreviewBean() {
 offerBean = (OfferBean) Contexts.getConversationContext().get("offerBean");
 }
}

I think other code is not relevant because in use case where "offerBean" object in OfferPreviewBean bean is not needed pop-up is working perfectly.

Thanks,
Uros!
