>             Project: JBoss Seam
>          Issue Type: Bug
>          Components: Core
>    Affects Versions: 2.0.1.CR1
>            Reporter: Ajay Gupta
>
> I have a SEAM component as follows:
> @Name("customer")
> @Scope(CONVERSATION)
> public class Customer
> {
>    @In (create=true)
>    private Address address;
>    @Factory(value="address")
>    public void getAddress()
>    {
>        this.address = ....//logic to populate address attribute in Customer.
>    }
>    public void doSomething() {
>    ....
>    }
> }
> In this case, when Customer.doSomething() is called and if customer.address = null, then the code as shown above fails with an exception stating:  "non-null address value should not be null".  To make the code above to work, I have to add required = false to the @In annotation.  SEAM still calls the factory method for address to populate the Address attribute in Customer before calling Customer.doSomething().  
> I would think that if create=true is specified on an @In annotation and required attribute is not specified on @In, then an exception should only be thrown if the attribute is truly null (if the attribute can be given a non-null value using a @Factory method, then required=true should not be enforced).
