Major This is from the original question on stackoverflow.com:
http://stackoverflow.com/questions/8004233/jsf-2-how-to-pass-an-action-including-an-argument-to-be-invoked-to-a-facelets-s
As an example, this view:
<ui:param name="p1" value="#{myBean}" /> <ui:param name="p2" value="submit" /> <ui:param name="p3" value="#{myBean.toString()}" /> <h:form> <h:commandButton value="submit" action="#{p1[p2](p3)}" /> </h:form>
with this bean:
@ManagedBean @RequestScoped public class MyBean { public void submit(String arg) { System.out.println("submit with " + arg); } }
works fine on Tomcat 7.0.22, but on JBoss AS 7 it fails while loading the page:

Chapter 1.19 of EL spec says:
ValueSuffix ::= '.' Identifier MethodParameters? | '[' Expression ']' MethodParameters? MethodParameters ::= '(' (Expression (',' Expression )* )? ')'
So, I think that Apache EL is right. Please fix ASAP. This is often used/useful in lists where you have a DELETE button per list row.
