Stuart Douglas updated JBSEAM-3507:
-----------------------------------
Attachment: seam-immediate-navigation-v1.diff
A patch that adds an immediate attribute to <navigation> that allows the rule to be run before the page actions are run.
> Allow for navigation rules to take effect before the view is displayed
> ----------------------------------------------------------------------

> Key: JBSEAM-3507
> URL: https://jira.jboss.org/jira/browse/JBSEAM-3507
> Project: Seam
> Issue Type: Feature Request
> Components: Core
> Affects Versions: 2.1.0.CR1
> Reporter: Stuart Douglas
> Attachments: seam-immediate-navigation-v1.diff
>
>
> Allow the developer the specify navigation rules that are evaluated before the view is rendered.
> For example, say we do not want logged in users to be able to view the login page, we cannot do this:
> <navigation>
> <rule if="#{identity.loggedIn}">
> <redirect view-id="/main.xhtml"/>
> </rule>
> </navigation>
> Instead you must either use a page action that contains the navigation logic, or specify a dummy page action such as ''.toString()
> and use this action as the from-action in your navigation rules. I propose we add an 'immediate' attribute to the navigation attribute that
> specifies that this action is evaluated before page actions are run.
