Nope, you can't... T4 used OGNL where you could, but T5 is pretty much just calls bean properties. See here:
http://tapestry.apache.org/tapestry5.2-dev/guide/propexp.html But this is a good thing, for it stops you from putting logic and programming in your template. So what you can do is: < t:if test="user.hasIdOf(99)"> and have a method on User: public boolean IsHasIsOf(int is) { return this.id == id; } If you don't like polluting your entities with T5 methods (esp if they're only used the once) then you could stick them on your page / component class where they're used.
