[jboss-user] [JBoss Seam] - Multiple component instances or how to use a component multi

Hi all, I really love bijection; it makes things so much easier. However, I have a requirement that makes it somehow hard to use contextual components. Let's suppose we have a Checkout page, were you can enter shipping and a payment addresses. These addresses obviously belong to a model of the same type. Let us further assume, that entering an address triggers some logic (beyond validation) so we need a controller, say: @Name("checkoutAddressController") | public class CheckoutAddressController { | | // maybe a persistence manager | @In SomeService service | | // our model | private Address address; | | // [...] | // some logic, getter / setter etc | | } Now on my checkout page, I want my address forms to have the above controller as a backing bean. So I need two instances of the same component on the same page. From the manual I read that maybe @Role could help here. But if the designer chooses to add another address form, I would have to add another Role. What if the designer wants to add 100 addresses? (yes, he's a maniac) Can composition help? I thought something like this? @Name("checkoutPage") | public class CheckoutPage | { | @In(scope=ScopeType.STATELESS, create=true) | CheckoutAddressController c1; | | @In(scope=ScopeType.STATELESS, create=true) | CheckoutAddressController c2; | | // or even | List<CheckoutController> ctls; | | @Create public void create() { | ctls = new ArrayList... | ctls.add(Component.getInstance("checkoutAddressController", ScopeType.STATELESS, true)) | } | } Will this work? Are there other solutions? Am I making things to complicated? Regards Patrick View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4068226#...
