problem using the pages.xml to call action method?

[fredf]

Hello all.

I am having problem using the action attribute in the page element in the file pages.xml.
I have a view-file which has a form and a datatable element.
I want to populate this datatable with data from a seam component when the user loads the page, not in the response of the form submit.

I have defined a method initAllMessages that populates my list (my list has @Out @DataModel) with data
and I use that list in the datatable

<h:dataTable value="#{allMessages}" var="message">
 <h:column>
 <h:outputText value="#{message.text}" />
 </h:column>
</h:dataTable>

I instruct seam to call the initAllData with the action parameter
in a page element in pages.xml like this:

<pages>
 <page view-id="/input.jsp" action="#{post.initAllMessages}" />
</pages>

The problem is that I get an exception:

2006-12-21 10:42:39,640 ERROR [org.jboss.portal.portlet.container.org_apache_myfaces_portlet_MyFacesGenericPortlet] The portlet threw an exception
javax.faces.el.EvaluationException: Exception while invoking expression #{post.initAllMessages}


The class in where I define my method to call implements an interface, has conversation scope and the Name annotation. The method it self has the @Create annotation
The seam view-file is loaded in a portlet contained in JBoss Portal.


Why am I getting this exception when seam tries to call the method?
Is there better/another way to populate data in a datatable on a non-faces get request?

thank you.

Having @Out @Datamodel on the same variable is a BAD idea - you're outjecting two different things to the same context variable. Just use @DataModel.

The most common way of populating data is via @Factory.

It's impossible to tell the problem from that little bit of a stack trace, you need to post the whole thing.

This is the complete stack trace.
In the middle it says:

Caused by: org.jboss.seam.RequiredException: In attribute requires value for component: post.message

That might be a clue..?

This is my action class:

@Name("post")
@Scope(CONVERSATION)
public class PostAction implements Post{
 Logger logger = Logger.getLogger(getClass().getName());
 private PostService ps = new PostService();

 @In @Out
 private Message message;

 @In(create=true)
 private transient FacesMessages facesMessages;

 @Create
 public void initAllMessages() {
 allMessages.add(new Message("hej din toker"));
 allMessages.add(new Message("sweet ride"));
 allMessages.add(new Message("cool page man!"));
 }

 @DataModel("allMessages")
 private List<Message> allMessages = new ArrayList<Message>();

 public String sayHello(){
 logger.info("\"" + message.getText() + "\"");
 try{
 ps.postMessage(message);
 }catch(UnfriendlyMessageException e){
 e.tellError();
 facesMessages.add("The message was rude. Behave, goddamit!");
 }

 return "recieved";
 }
 @Remove
 public void remove(){}
}

Can you see any obvious flaws in my code?

Yes. You've specified that message must be injected and outjected (i.e. not null on both injection and outjection). It is null. use required=false

That did "susen" (as we say in sweden) ie: It works.
Thanks!!
