Damn, get an exception with f:attribute. I thought that should work.
To do <h:commandLink action="college"/> I would have to do a choose/when
condition checking the value of #{linkPage} which can have like 12 different
values. Seems like a messy solution to me.

How about using the f:attribute tag for name="action"?

You are correct. It's trying to resolve it as a method binding.
You need to either use
<h:commandLink action="#{yourBean.yourMethodReturningCollegeAsAString}"/>
or
<h:commandLink action="college"/>
The attribute "action" takes only a string literal or a method binding
that returns a String. It does not take a value binding that
evaluates to a String. So if you need the action target to be
variable, you need to write java code to perform this logic.
Possibly you could use some kind of JSP EL expression instead of a JSF
EL expression, but I wouldn't recommend this approach.
