[jboss-user] [JBoss Seam] - outputlink order problem
hello
i really don't get the reason for this strange problem:
first my environment:
the entity a simple foto with a number attribute
| import java.io.Serializable;
|
| import javax.persistence.*;
|
| import org.jboss.seam.annotations.Name;
|
| @Entity
| @Name("photo")
| public class Photo implements Serializable
| {
| private static final long serialVersionUID = 1L;
|
| @Id @GeneratedValue
| private long id;
| private String number;
|
| public long getId() { return id;}
| public void setId(long id) { this.id = id; }
|
| public String getNumber() { return number; }
| public void setNumber(String number) { this.number = number; }
|
| }
|
|
the facelet
| <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
| <html xmlns="http://www.w3.org/1999/xhtml"
| xmlns:ui="http://java.sun.com/jsf/facelets"
| xmlns:h="http://java.sun.com/jsf/html"
| xmlns:f="http://java.sun.com/jsf/core"
| xmlns:s="http://jboss.com/products/seam/taglib">
| <head>
| <meta http-equiv="Content-Type" content="text/html;
charset=ISO-8859-1" />
| </head>
| <body>
|
| <h:form>
| <h:inputText value="#{photo.number}"/>
| <h:commandButton type="submit" value="Add"
action="#{formAction.addItem}"/>
| </h:form>
|
| <h:outputLink value="test.html" rendered="#{myservice.value ==
true}">Is True</h:outputLink>
|
| </body>
| </html>
|
|
with the corrosponding pages def.
| <page view-id="/test.xhtml">
| <action execute="#{myservice.load}"/>
| </page>
|
and the bean from where the page gets the data
|
| import org.jboss.seam.ScopeType;
| import org.jboss.seam.annotations.Logger;
| import org.jboss.seam.annotations.Name;
| import org.jboss.seam.annotations.Out;
| import org.jboss.seam.annotations.Scope;
| import org.jboss.seam.log.Log;
|
|
| @Name("myservice")
| @Scope(ScopeType.EVENT)
|
| public class MyServiceBean
| {
| @Logger
| private Log log;
|
| private boolean value = true;
| public boolean getValue() { return this.value; }
|
| @Out(required=false)
| private Photo photo;
| public Photo getPhoto() { return this.photo; }
|
| public void load()
| {
| log.info("loading");
|
| this.photo = new Photo();
| this.photo.setNumber("testPhoto");
| }
| }
|
|
so when the page is loaded the method load is executed and the photo is being outjected.
which i then access in my facelet form
now to the strange part:
| import javax.ejb.Remove;
| import javax.ejb.Stateful;
|
| import org.jboss.seam.annotations.Destroy;
| import org.jboss.seam.annotations.In;
| import org.jboss.seam.annotations.Logger;
| import org.jboss.seam.annotations.Name;
| import org.jboss.seam.log.Log;
|
| @Stateful
| @Name("formAction")
|
| public class FormActionBean implements FormAction
| {
| @Logger
| private Log log;
|
| @In
| Photo photo;
|
| public void addItem()
| {
| log.info("adding: "+photo.getNumber());
| }
|
| @Remove @Destroy
| public void Destroy() {}
|
| }
|
| public interface FormAction
| {
| public void addItem();
| public void Destroy();
| }
|
|
when i try to submit the form and access the addItem method it won't work.
an exception is thrown because @In is not non-null
BUT it works when i put the outputlink above the form.
i found out its the rendered attribute which messes it up. if i omit it there won't be
an error
i hope someone can help me i tried to post all the necessary files
thanks in advance
