Currently JSF does not support decomposition of a web application into smaller
reusable fragments. For example, you can't build a collection of pages, managed
beans, and navigation rules to perform a common task like completing a consumer
transaction (enter shipping info, billing info, etc.) and package it as a
reusable component. Instead, JSF treats a web application as one monolithic
entity, which becomes problematic in large application. It would be useful to
able to package a portion of a web application into a reusable library.

Prepare to delete "spec" subcomponent.

I think the Servlet 3.0 spec addresses this. If you feel it does not, please re-open.

What I had in mind was more along the lines of a Spring WebFlow or an Oracle ADF
Task flow. I don't believe there's anything like this currently covered by any
of the JavaEE specifications.

This would be great to have, but it's not on the radar at the moment. Feel free to contribute it!

Should programmers use facelet includes to factor out modal dialogs, tab content, & the like?

Comment by daschneider [ 18/Apr/11 ]

The intent of this feature is not to handle page fragment use cases as the above comment suggests. It's intended to allow creation of application fragments that consist of multiple pages, managed bean definitions, navigation rules, etc. that can be packaged up into reusable units. For example, say you have a shopping site checkout flow that consists of several pages to collect billing informaiton, shipping information, confirm the order, etc. How can you build this as a reusable unit that can be used by multiple faces web applications? That's the type of use case this feature intendes to address.

This issue is a duplicate to http://java.net/jira/browse/JAVASERVERFACES_SPEC_PUBLIC-730.
they are sharing the same goal : modularization of a JSF application and it wouldn't make sense to achieve it in two different ways. So I think it is better to close this one in favor of the Tasksflow feature which is already meaningful.

Comment by Ed Burns [ 04/Feb/12 ]

This really is a subset of the requirements of task flows.
