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:
