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.
