pages.xml redirect if loggedIn

[damianharvey]

My understanding is that navigation rules in pages.xml fire after the page render (eg. after an action). Is there any way to use a navigation rule to fire before the render (ie. similar to an action)?

Currently I have a rule in my login.page.xml that redirects users to the home page after they login successfully. This works fine, however if a user has bookmarked the login page and calls it again after login, the navigation rule is not hit (as it is before the render) and the login page is displayed again - and typically the user thinks that they've been logged out.

<page>
 <navigation>
 <rule if="#{identity.loggedIn}">
 <redirect view-id="/secure/home.xhtml"/>
 </rule>
 </navigation>
</page>

This same rule exists in the Booking example and the same behaviour occurs.

I've designed around this but am still curious as to how pages.xml might be used to get around this.

Cheers,

Damian.

Yes, you can fire an action before render.

I resolved a similar problem as follows:

<page view-id="/login.xhtml" action="#{authenticator.checkIfLoogedIn}">
 <navigation from-action="#{authenticator.checkIfLoogedIn}">
 <rule if="#{identity.loggedIn}">
 <redirect view-id="/home.xhtml"/>
 </rule>
 </navigation>
 <navigation from-action="#{identity.login}">
 <rule if="#{identity.loggedIn}">
 <redirect view-id="/home.xhtml"/>
 </rule>
 </navigation>
 </page>

The authenticator.checkIfLoogedIn method is called before render the page (it is an empty dummy method). So, if the user is already logged in he is redirected to correct page instead showing the login page again.

HTH.
