Newbie question: access session attribute from view

[javri28]

Hi everybody!

I have one may ba stupid question, but I could't find any answer on it...

On my page I have to check if the user is logged in(let's say there should be shown different images for logged and not-logged user).

I have User component in session scope. During registration I'm doing common thing:

Contexts.getSessionContext().set("loggedIn", true);

The only condition that I have found for my "rendered" attributes on pages to check if the user is logged-in is #{user.userName != null}.

Is this the only way to do it on the page?
I just whant to be sure before I use it everywhere(not in many places, but it doesn't metter)

I hope I have explained a problem correctly.

Thanks in advance!

Since you store the "loggedIn" in the session scope, you can use the "rendered" to be something like
<.... rendered="#{loggedIn != null}" />

Seam automatically would look for the loggedIn attribute in all the scopes and you could render the components accordingly.

If I understand you correctly, this should work:

rendered="#{sessionScope.loggedIn}"

Thanks a lot, guys!
Both variants are functioning properly.

For what it's worth, #{sessionScope.loggedIn} should be a little faster. "sessionScope" is an implicit object. Implicit objects are always evaluated first by the ELResolver. Searching of all the scopes usually happens last.

I agree - this is a better way - to know thet you are using the attribute of the RIGHT SCOPE.
