----------------------------------

Hey Brian,

I reproduced the issue on metamer. I verified that function on data attribute is called twice.

Here is the [facelet|https://github.com/richfaces/qa/blob/master/metamer/application/src/main/webapp/components/a4jJSFunction/rf-12510.xhtml] and here the [test|https://github.com/richfaces/qa/blob/master/metamer/application/src/main/webapp/components/a4jJSFunction/rf-12510.xhtml].

I also reproduced the issue on Tomcat 7 and JBoss AS 7.1.1.Final, both on Chrome and Firefox.

> When a4j:jsFunction is called then function on data is called twice. Once before action and then after action. How to disable it? RF 3.3.3 have called it just once.
> {code}
> <a4j:jsFunction name="myFunc" data="#{myBean.data}" action="#{myBean.action}"/>
> {code}
> So that myBean.data is called before action call and after action call. How to prevent it?
