How do I select an initial page after login chosen by user r

[zzztimbo]

I'm trying to edit my pages.xml to send a user to a specific page based on their user role. How do I do that?

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

For instance, how do I modify the above so that users with role = 'user' will be sent to user.xhtml while users with role = 'poweruser' will be sent to poweruser.xhtml?

One idea could be to extend the Identity class in order to return a custom outcome (public String login()) based in your roles and then use it in the pages.xml.

If the users have one role only, you could write it like this:

<page view-id="/login.xhtml">
 <navigation from-action="#{identity.login}">
 <rule if="#{s:hasRole('user')">
 <redirect view-id="/user.xhtml"/>
 </rule>
 <rule if="#{s:hasRole('poweruser')">
 <redirect view-id="/poweruser.xhtml"/>
 </rule>
 </navigation>
</page>

what about the

<rule if-outcome="loggedIn">

portion of the logic? if the user is already logged in and they try to go to the login screen, it should send them to the appropriate page: either user or poweruser.

[shane.bryzak]

If the user has either of those roles then it means they will be logged in, there is no need to check for it explicitly.

The best option is:

<rule if="#{identity.loggedIn}">

No need for any special changes to Identity.

[gavin.king]

Oh, oops, I misunderstood.

[zzztimbo]

The best option is:

<rule if="#{identity.loggedIn}">

No need for any special changes to Identity.

What should the behavior be for this:

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

I copied this from the pages.xml of the booking example.
After I log in from home.seam, I get taken to main.seam. This is to be expected. When I explicitly go back to home.seam, should it redirect me again to main.seam? The current behavior I am getting is that it just sits there at home.seam. Logging in again of course works and takes me appropriately to main.seam.

If the users have one role only, you could write it like this:

<page view-id="/login.xhtml">
 <navigation from-action="#{identity.login}">
 <rule if="#{s:hasRole('user')">
 <redirect view-id="/user.xhtml"/>
 </rule>
 <rule if="#{s:hasRole('poweruser')">
 <redirect view-id="/poweruser.xhtml"/>
 </rule>
 </navigation>
</page>

I'm getting an exception.

javax.faces.el.EvaluationException: Cannot get value for expression '#{s:hasRole('user')}'

This syntax works fine when I restrict page access using:

<page view-id="/user.xhtml">
 <restrict>#{s:hasRole('user') or s:hasRole('admin')}</restrict>
</page>

This is a bug with MyFaces not supporting EL Functions. We're currently working on a solution, please hold :)

[shane.bryzak]

No easy fix I'm afraid.
