Well, I found out that Seam does allow multiple elements inside a root element,
but only if they're in the right order! For instance, this doesn't work:
| <rule if-outcome="FP1">
| <redirect view-id="page1.xhtml" />
| <begin-conversation join="true" pageflow="PF1" />
| </rule>
|
but this does:
| <rule if-outcome="FP1">
| <begin-conversation join="true" pageflow="PF1" />
| <redirect view-id="page1.xhtml" />
| </rule>
|
So, with that discovery, I was able to greatly reduce the configuration needed,
to the point that I'm pretty much satisfied now :). Only unfortunate things are
that I still need a controller JavaBean to force the navigation rules to be
evaluated on page load and that beginning a pageflow doesn't automatically
redirect to its start-page.
The solution:
| <page view-id="/controller.xhtml" action="#{controller.getFlow}">
| <param name="flow" value="#{controller.flow}" />
|
| <navigation>
| <rule if-outcome="PF1">
| <begin-conversation join="true" pageflow="PF1" />
| <redirect view-id="page1.xhtml" />
| </rule>
| <rule if-outcome="PF2">
| <begin-conversation join="true" pageflow="PF2" />
| <redirect view-id="page1.xhtml" />
| </rule>
| <rule if-outcome="PF3">
| <begin-conversation join="true" pageflow="PF3" />
| <redirect view-id="page4.xhtml" />
| </rule>
| </navigation>
| </page>
