Seam 1.2.1 GA
Tomahawk - 1.1.6
Hello Seamers,
Wrt my stateful bean error, I am still struggling with this.
One of my scenarios follows:
- I have an SFSB, CONVERSATION scope, containing a @DataModel
@Name("serviceMgmt")
- The Datamodel is used to render a data table using t:dataTable
- I have an ajax poll that checks the table bean for updates every 4s
- The table @Create method is annotated with @Begin so the table bean maintained in an
LRC.
- The table rows have an s:link rendered which is used to edit the
objects displayed in the table.
- The editor, another SFSB, is launched by an action annoated with
@Begin(nested=true), so the editing is done in a nested LRC.
@Name("sserviceEditor")
- The editor injects another SFSB (a table),with @In(create=true)
This bean should not exist inthe parent conversation.
@Name("serviceEndPointMgmt")
It is a reference to serviceEndPointMgmt causes the error.
Normally, evertyhing works correctly. The workspace switcher shows the
parent and nested conversation as I would expect.
However, if I leave the page alone for 15 minutes, touching nothing,
and then try the edit link, I get the "stateful bean error".
The error is due to a reference to the component "serviceEndPointMgmt"
(see code & logs below)
The ajax poller keeps the conversation alive, and the workspace
switcher confirms that the parent conversation is still active before
the attempted edit.
The table backing bean is annotated like so:
| @Stateful
| @Scope(CONVERSATION)
| @Synchronized
| @Name("serviceMgmt")
| @LoggedIn
| public class ServiceTableBean extends GenericTableBean implements ServiceTableLocal
| {
| ....
| }
|
The s:links in the table rows are defined like this:
| <s:link value="#{row.name}"
| title="Edit this service definition."
| action="#{sserviceEditor.edit(row.id)" >
| <f:param name="rowId" value="#{row.id}"/>
| </s:link>
|
The editor component:
| @Stateful
| @Scope(CONVERSATION)
| @LoggedIn
| @Synchronized
| @Conversational
| @Name("sserviceEditor")
| public class ServiceEditBean extends GenericEditorBean implements ServiceEditLocal {
|
| @In(create=true)
| @Out
| ServiceEndPointTableLocal serviceEndPointMgmt;
|
| ....
|
| @Begin(nested=true)
| public String edit(String id)
| {
| ....
| ....
|
| // The nested conversation has not started yet...
|
| // Here we get a "can't find stateful bean error" ... sometimes.
| serviceEndPointMgmt.setServiceProxy( this.serviceEntry );
|
| }
|
SEAM Logs:
I turned up the Seam logging level. I can see that the offending bean
seems to be available, but then the reference to it somehow triggers
its removal.
I do not really understand why serviceEndPointMgmt bean is initially
found in the conversation context (maybe because create=true), or why
would it be subsequently removed after/by the RootInterceptor?
