OK, so, at least for conversation descriptions and timeouts, I've taken a whole
new tack now. I hated seeing conversation.switchableOutcome() everywhere in the
example apps, and I could not quite figure out why. It just *felt* ugly and
wrong.
Now I've decided that this stuff is really metadata about the "state". The
"state" is welldefined when you are using jPDL pageflows, so you can just write
stuff like:
<page name="browse"" view-id="/brows.xhtml" timeout="300000">
| <description>Search results for: #{search.searchPattern}</description>
| <transition name="select" ... />
| </page>
Unfortunately, for the case of JSF navigation, we have a stateless navigation
model, where there are welldefined transitions, but no welldefined *sates*.
Upon reflection of this issue, I decided that it is OK to use the closest thing
to a state in JSF, which is the page.
Now, JSF has no such thing as a place to put metadata about a page, so I added
the concept of a pages.xml file, which lives next to faces-config.xml in the
WEB-INF directory.
Here is an example:
<page view-id="/main.xhtml" timeout="300000">Search hotels:
#{hotelBooking.searchString}
<page view-id="/hotel.xhtml" timeout="300000">View hotel: #{hotel.name}
<page view-id="/book.xhtml" timeout="600000">Book hotel: #{hotel.name}
<page view-id="/confirm.xhtml" timeout="600000">Confirm:
#{booking.description}
This essentialy defines the states (well, "non-states") that the navigation
rules refer to.
This let me *really* clean up the code of the booking and issues example apps.
