NotSerializableException:ThreadLocal when using PAGE scope
Hello all.
I'm porting the display side of an existing EJB3 backed webapp to
Seam w/ JSF/Facelets and EJB3 on Jboss AS.
( jboss 4.0.5GA w/ Seam 1.1.1GA )
A few pages are working front to back so the plumbing is at least generally functional.
The current issue is that i have a Seam managed bean (pojo) into which is injected another pojo that has a SESSION scope.
Things work fine if my first object is event scoped or session scoped, but if i change the scope to "PAGE" then i get this serialization Exception.
is this supposed to work ?

also, is this mention of JspStateManager in the stacktrace a concern given that JSPs aren't supposed to be involved here at all ?

Here are the classes in my stripped down test case.
the bean that's injected:
@Name("loginSessionFoo")
@Scope(ScopeType.SESSION)
public class TestSessionScoped implements Serializable {
@Logger
private Log log;
private String foo;
public String getFoo() {
return foo;
}
public void setFoo(String foo) {
this.foo = foo;
}
}
the one into which it is injected
@Scope(ScopeType.PAGE)
@Name("contentDisplay")
public class ContentDisplay implements Serializable {
@Logger
private Log log;
private Date oneDayAgo;
@In(value="loginSessionFoo", create=true)
private TestSessionScoped foo;
/**
* Currently acts only to give out a date 1 day ago today to see
* that's used for display calculations.
*
*/
//CHECK does this still seem like a good idea
@Create
public void initialize() {
Calendar cal = new GregorianCalendar();
cal.add(GregorianCalendar.DAY_OF_YEAR, -1);
this.oneDayAgo =cal.getTime();
}
// some action methods removed....
}
any pointers appreciated. thanks.
