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!
