Q:

org.jboss.seam.RequiredException: @In attribute requires non-null value: selectAccountPageBean.accountSessionBean

The "Caused by:" section of my stack trace says:
Caused by: org.jboss.seam.RequiredException: 
@In attribute requires non-null value: selectAccountPageBean.accountSessionBean

The Page-scoped bean has this:
@Name("selectAccountPageBean")
@Scope(ScopeType.PAGE)
public class SelectAccountPageWidgetBean 
    extends BaseWidgetBean implements Serializable
{
...
    @In(create = true)
    private AccountSessionBean accountSessionBean;
...
}

The Session-scoped bean has this:
@Name("accountSessionBean")
@Scope(ScopeType.SESSION)
public class AccountSessionBean implements Serializable
{
...
}

When I refer to the Page-scoped bean from a facelet, I get the error.
I've done this same thing in other apps and it worked fine.  Is there some configuration value that I'm missing somewhere?

A:

I'm not sure which change fixed it, but we did two things.

We added in a components.properties file.  Someone suggested that we should have one on
the classpath even if it's empty.
We had a problem with the package that the component was in.  The package structure was 
something like:
foo.bar.baz

But the component was in a directory like:
foo/bar/pirate/monkey/baz

We simply moved the file to the proper directory.
