In attribute requires value for component

[taprogge]

Hi!
I am totally confused...
I am working with an existing Seam application running inside JBoss Portal (JBoss 4.0.4.GA, EJB3 rc8, Portal 2.4.0.CR3) with the MyFacesGenericPortlet.
All existing components work.
Now I tried to add a new component and get said error.
I have stripped it down in trying to find the cause, but had no luck.
Perhaps one of you can tell me what I am doing wrong.

This is my POJO to hold the entered information. Even scoping it "SESSION" did not make any difference.

@Name("userinput")
@Scope(SESSION)
public class UserInput {

 private String username;
 private String password;

 public String getPassword() {
 return password;
 }
 public void setPassword(String aPassword) {
 this.password = aPassword;
 }
 public String getUsername() {
 return username;
 }
 public void setUsername(String aUsername) {
 this.username = aUsername;
 }
}

This is my SessionBean:

@Stateful
@Conversational(ifNotBegunOutcome = Outcome.REDISPLAY)
@Scope(CONVERSATION)
@Name("usercreate")
public class UserActionBean implements UserAction {

 private static Logger logger = Logger.getLogger(UserActionBean.class);

 @PersistenceContext(type = EXTENDED)
 private EntityManager em;

 @In(create = true)
 private UserInput theUser;

 @Begin
 public String beginStuff() {
 logger.info("begin called");
 logger.info("Data so far: username="
 + theUser.getUsername());
 return Outcome.REDISPLAY;
 }

 @Remove
 @Destroy
 public void destroy() { }
}

And this is the jsp I use as default view for the portlet:

<f:view>
<h:form>
<table border="0">
 <tr>
 <td align='left'>username:</td>
 <td><h:inputText id="username"
 value="#{userinput.username}"
 required="true" />
 <h:message style="color:red" for="username" /></td>
 </tr>
 <tr>
 <td align='left'>password:</td>
 <td><h:inputText id="password"
 value="#{userinput.password}"
 required="true" />
 <h:message style="color:red" for="password" /></td>
 </tr>
 <tr>
 <td height='60' align='left'>
 <h:commandButton type="submit" value="create user"
 action="#{usercreate.beginStuff}" /></td>
 <td align="right"><input type="reset" value="reset"></td>
 </tr>
</table>
<h:messages style="color:red" />
</h:form>
</f:view>

Now, entering no information at all results (correctly) in "required" messages to be displayed for each field.
Entering any data and hitting the button results in a

org.jboss.seam.RequiredException: In attribute requires value for component: usercreate.theUser

being thrown.

Any thoughts?

You are trying to inject the seam component: "theUser" while your Seam component is called: "userInput"

either:
1) Change
private UserInput theUser;
to
private UserInput userInput

2) Change
@Name("userinput")
to
@Name("theUser")

3) Change
@In(create = true)
to
@In(value=userInput, create=true)

Indeed...
Sometimes I just hate myself ;-)

You are, of course, correct. After changing the names, it works fine.
It's even in the Seam Reference Guide for crying out loud.

Well, thanks a lot for saving me from my own ignorance.

Phil
