[JBoss Seam] - Can't find Stateful Bean...
by pdpantages
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?

[JBoss and NetBeans] - Re: Netbeans + Seam Plugin = Success !!
by ericcart
I didn't try sem-gen command line. I used all the others tools. For example Jboss IDE Beta, creating a JBoss IDE Project (EAR, WAR and EJB... and adding the libraries and files). I thought Seam was supported... It's very tricky to configure and the environment does not help.
I just checked sem-gen command line... ant setup... ant new-project... etc... It's very far from I was looking for.... and seam documentation does not describe to use it as a fundamental thing to configure a project (may be, because It's not very handy to be running ant commands).
The key with netbeans is that Seam Plugin uses sem-gen command line as a wizard (very easy to create all the project configuration).
In a couple of hours, I migrated all the tests and I'm working with the final project at netbeans.
Thanks,
Anibal
