> Page actions are incredibly useful, but sometimes they can get in the way during a postback. I would like to see a postback attribute added to the <action> tag that can be used to disable the action on postback. It's possible using a conditional, but it is ugly and a lot of typing.
> Here is the logic that would go into Pages.java
>     private boolean isPostBack(FacesContext facesContext)
>     {
>         return facesContext.getExternalContext().getRequestParameterMap().
>               containsKey(ResponseStateManager.VIEW_STATE_PARAM);
>     }
> The conditional alternative would be:
> <action execute="#{component.action}" if="#{empty param['javax.faces.ViewState']}"/>
