How do you call List.size() from a JSF 2.0 Facelets Template?

Question

What is the syntax for calling list.size() in a JSF 2.0 Facelets template (eg, using an h:outputText element)?

Answer 1

It's not a problem with JSF 2.0 exactly. The JSF spec still requires a class that conforms to the bean spec. The collection classes don't do that with the .size() method. It would still have to be .getSize(). Given the need for a "standard" way to access the class values, we're not getting around that in JSF any time soon. Somebody needs to fix the collection classes.

Answer 2

How about this:

<h:outputText value="#{fn:length(someBean.someList)}" />

You'll need to reference the functions taglib in your JSF page (URI: http://java.sun.com/jsp/jstl/functions).

Answer 3

just try #{myBean.myList.size()}
