dvd store question

[kgoedert]

In the dvd store example in the admin page there is this

<s:button action="#{accept.viewTask}" taskInstance="#{task}"
value="Review"/>

In the AcceptAction there is an injection of

@In Long orderId;

and in the viewTask method is the orderId is used to do the search. My question is, how is orderId injected? Or, which property on the admin page sets the value of orderId?

Thanks

It is placed in the business process context in CheckoutAction.java:

@Out(scope=ScopeType.BUSINESS_PROCESS, required=false)
long orderId;
