Hi,
I generated a new form using sean-gen (seam new-form) and added another field to it using an @In annotation:
@Stateful
@Name("dummy")
public class DummyBean implements Dummy
{
@Logger private Log log;
@In StatusMessages statusMessages;
@In private String bar;
private String foo;
public void doStuff()
{
String msg = "dummy.doStuff() action called with foo: #{dummy.foo} and bar: #{bar}. instance variable for bar:" + bar;
log.info(msg);
statusMessages.add(msg);
}
@Length(max = 10)
public String getFoo()
{
return foo;
}
public void setFoo(String value)
{
this.foo = value;
}
@Remove
public void destroy() {}
}
The interface is this one:
@Local
public interface Dummy
{
public void doStuff();
public String getFoo();
public void setFoo(String value);
public void destroy();
}
The problem is, when I try to access the properties I get:
javax.faces.FacesException: javax.el.ELException: /dummy.xhtml @22,52 value="#{dummy.foo}": Error reading 'foo' on type org.javassist.tmp.java.lang.Object_$$_javassist_seam_2

.

My view is this:

If I remove either 'fooField' or 'barField' the view renders and works correctly, but if I try to use both at the same time I get the above exception.
I also noticed that if I use only @In annotations (remove the accessor methods from the bean) the page works.
Is this something expected and I should be doing my homework before asking?
I'm using JBoss 5.1.0.GA, Seam 2.2.0.GA and Java 6.
