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
