Seam Injection of Collections into backing beans

[ngeadah]

How would one achieve injection of a Collection of Seam components into a backing bean? I know I can setup outjection of a List of components using an @DataModel annotation (coupled with an @Factory method it works great). I want to do injection...

i.e. Assume a Seam component exists (MyComponent). I would like my backing bean to have:

@In
private List<MyComponent> myComponents;

Assuming this is supported, how should my JSF be setup to inject correctly? Would something similiar to this work?

<h:inputText id="total" value="#{MyComponent[0].attribute}"/>

I think via @In(value="#{myComponents}"). Like that it's possible to inject non-Seam-components.

I don't know if you can uses an index number to access array elements. Try it out. But I'd suggest that you use ui:repeat or h:dataTable instead in order to iterate over all elements.

Why don't you try it out?

@In myComponents is pretty much exactly equivalent to @In(value="#{myComponents}").

Is there a wiki page or guide anywhere that goes into more detail about mixing JSF and Seam? All I've done is migrated some JSF backing beans to Seam components, but I never thought of actually mixing Seam into JSF. What are the limitations involved? I presume backing beans don't participate in conversations or business processes, for example...

There is no problem at all in using a JSF managed bean in a Seam app.
