[jboss-user] [JBoss Seam] - Cannot @In(ject) a Stateful Session Bean into another Statef
Hello,
we're evaluating SEAM 1.2.1 together with ICEfaces 1.6 Alpha and Facelets on GlassFish
v2. It was easier than we thought, but we didn't manage to inject (or biject!) a
stateful session bean into another.
What we want to do is the following:
| - Have a "controller" bean for every window/tab
@Scope(ScopeType.CONVERSATION) that holds information about currently selected item,
navigation history etc.
| - Have a "model" stateful session bean for storing available items for each
view in use.
|
|
| This way one could write the following expression
|
|
| | <h:outputText value="#{controller.selected.name}"/>
| |
|
| (Bean-Code is at the end of the posting...)
|
|
|
| What happens is the following:
|
|
| | * The ControllerBean is created in Conversation-Context when used in the
presentation layer.
| | * In NamingManagerImpl.java the following componentId is used as the namespace for
lookup "MY_EAR_MY" (where "MY_EAR" is the (Eclipse)
application-project and "MY" is the name of the web-application project)
| | * Note: this also works for the other component if used (and created) in the
presentation layer (i.e. "model.getItems()")
| | * @In(jection) takes place, but of course there is no ModelBean in the session
context
| |
|
| Now the Seam-Interceptor tries to auto-create a ModelBean, but when it comes to the
lookup NamingManagerImpl retrieves the componentId relative to the ControllerBean
| (using ComponentInvocation ci = im.getCurrentInvocation();)!
|
| Thus it searches the namespace
componentId "MY_EAR_MY_EJB.jar_ControllerBean_77129428636467201" which fails
because there is no ModelBean component registered there.
|
| But: If we change the componentId in the debugger manually to "MY_EAR_MY"
everything works fine. Question is did we make a configuration error or is this a bug? We
can't explain why direct creation works but @AutoCreate in another component does not.
Any hints and help appreciated, thanks in advance!
