Conditional templating with the EL

[christian.bauer]

I have a datatable and in one of the columns I need to decide what to render based on the type of an object. I looked for an "instanceof" operator in the Unified EL, but it's only a reserved keyword with no implementation.

I've seen solutions that use a custom JSF component, this seems overkill for such a common scenario. Does anyone have a more practical solution?

If your using facelets, why not use a custom function

rendered="#{my:instanceOf(object, 'java.lang.String')}"

public static boolean instanceOf(Object object, String clazz) {
 return Class.forName(clazz).isAssignableFrom(object.getClass());
}

Can you do #{foo.class='MyClassName'} ?

Doh, #{node.class.simpleName} works great.
