    Weird injection issue

    Louis Coetzee Apprentice

      Hi,

      I have been having trouble with regard to a very weird injection issue, where some elements are injected, while others are not (this happening while the conversation has ended (I think ;-))). I will try and explain:

      I have an entity bean:

      @Entity
      @Name("grouping")
      @Table(name = "grouping")
      public class Grouping {...


      This gets outjected in one of my beans (but using a different name):
      @Out(required = false , scope = ScopeType.CONVERSATION)
       private Grouping selectedGroupingForView;
      

      selectedGroupingForView is visible in the conversation context through the debug.jsf page.

      In another bean (contentManagementBean) I inject selectedGroupingForView.


      @In(required = true,value="selectedGroupingForView")
       @Out(required=true)
       private Grouping selectedGroupingForView;
      

      During normal usage this works as expected, with the selectedGroupingForView outjected and then injected and used (I have a page "viewContent" from where a s:link action can be invoked on contentManagementBean (<s:link action="#{contentManagementBean.createContent}" ... ) ).

      However, when some time is allowed to pass before invoking the link the contentManagementBean is created with things started to be injected (ideally it should have thrown me out saying that a valid conversation is required). Quite a few things are injected, but I always get an exception saying that selectedGroupingForView is required). Looking in the log file I see the following:

      [org.jboss.seam.Component] trying to inject with hierarchical context search: content
      [org.jboss.seam.contexts.Contexts] found in conversation context: content
      
      [org.jboss.seam.Component] trying to inject with hierarchical context search: selectedGroupingForView
      , but note that it has not found it, while it did inject other elements.

      Subsequently I get the following exception:
      ERROR [org.jboss.seam.interceptors.ExceptionInterceptor] redirecting to debug page
      org.jboss.seam.RequiredException: In attribute requires value for component: contentManagementBean.selectedGroupingForView

      This has been giving me quite a tough time, so any suggestions are welcome.

      Thanks

          Sounds like a conversation timeout to me. What about it you use no-conversation-view-id?

          • 2. Re: Weird injection issue
            Louis Coetzee Apprentice

            I agree that it is a conversation timeout.

            I have

            <component name="org.jboss.seam.core.pages">
             <property name="noConversationViewId">/public/error/errorPage.xhtml</property>
             </component>
            
            in components.xml

            as well as
            <pages
             no-conversation-view-id="/public/error/errorPage.xhtml">
            ...
            
            in pages.xml.

            As I understand it, it should through me out if I try to access the bean without the conversation.

            The complete method call from the xhtml page into the bean is:
            <s:link action="#{contentManagementBean.editContent}"
             id="editContent">
             <h:outputText value="#{msgs.editContent}" />
             </s:link>


            with the call itself:
            public String editContent() {
            .
            .
            
            


            The weird thing is that some things are still injected, while others are not.

            Regards
            L

              Well, things that had some other scope than CONVERSATION would still be injectable, as would anything with create=true.

              So, what you should focus on is why no-conversation-view-id is not working. What does the Seam debug log have to say?

                What I can see in the log file is that the bean (viewContentBean), which outjects the element initially (selectedGroupingForView) has been destroyed earlier

                [org.jboss.seam.interceptors.RemoveInterceptor] Stateful component was removed: viewContentBean


                but it seems that the conversation is still restored:
                [org.jboss.seam.core.Manager] Found conversation id in request parameter: 2
                2006-11-21 13:11:48,604 DEBUG [org.jboss.seam.core.Manager] Restoring conversation with id: 2
                
                . Obviously it does not find the various things to inject (and throws the exception because of the required=true).

                Still trying to decipher the log file to see why the conversation is still propagated...
