Does that answer your question?
D'oh, thanks for seeing the obvious. works great with s:hasRole
Now comes the next question, I didn't know you could use semi-colon notation in an EL expression, can somebody tell me what makes it different from the regular dot (.) notation ?
It's often good to know why things are such a way in order to remember it.
I don't think a colon has any special meaning in normal EL but Seam has an own EL-resolver so they are free to use whatever they like. It is probably needed anyway in order to separate it from a normal EL-resolve involving an variable named s.
