## Ajax4Jsf
Tag actionparam

A combination of the functionality of two JSF tags, <f:actionListener>; and <f:param>. At the render phase, it's decoded by parent component (<h:commandLink>; or like) as usual. <br /> At the process request phase, if the parent component performs an action event, update the value specified in the "assignTo" attribute as its value. <br /> If a converter attribute is specified, use it to encode and decode the value to a string stored in the html parameter. <br />
