JSF expression language (EL) question

I have a menu item that I want to show/hide only if the user has certain roles.

I'm using the rendered attribute for this, but I'm stuck on something. This works ...

rendered="#{loginHandler.hasStaffRole}"

... but this does not ...

rendered="#{loginHandler.hasStaffRole or loginHandler.hasInstructorRole or loginHandler.hasVolunteerRole}"

The error I get in Eclipse for the problem one is:

"cannot apply expression operators to method bindings"

Any idea how I should fix this?

I had the same issue: rendered="#{user.canEdit or user.isRole('ROLE_1', 'ROLE_2')}"

The "solution" for my Eclipse 4.3 was to reverse the arguments: rendered="#{user.isRole('ROLE_1', 'ROLE_2') or user.canEdit}"

Adding parentheses did not cure it. Your mileage may vary.

Answering my own question. The problem was the LoginHandler.hasStaffRole() method needed to be worded LoginHandler.isHasStaffRole() in order to be recognized as a property. (In the end I changed it to .isUserHasStaffRole.)

Thanks.
