Creating EL functions (non-facelets)

[lightguard]

I noticed that Seam cheats and the s: functions like s:hasRole aren't facelet functions.  Is there a way to do the same thing in my app that Seam is doing (and be able to use both) or am I limited to facelets functions which are only available in the view layer?

SiA:

The function s:hasRole maps to the static method defined here. This method uses
the identity component to verify whether the authenticated user is a member of the
given role:
public static boolean hasRole(String name) {
return Identity.instance().hasRole(name);
}

This most likely means that you can programmatically (i.e. from your Seam components) execute this method as well.

Yes, but I want to be able to create my own EL function that can be used like the Seam ones (inside pages.xml, annotations etc) but it looks like Seam doesn't allow that kind of extension atm.

I think you're talking about adding your own custom tag libs.  If you want to use s:foo then you'll most likely have to modify the Seam codebase.  Otherwise, you can use foo:bar or similar to create your own...

Yep, exactly.  Dan Allen said they're looking at better extensibility in Seam 3, but we're probably SOL until then.
