RequestAction

gives the ability to execute actions when url parameters/values are submitted. To do that, RequestActionValue must be called too, as it is shown at example below.

<xvw:requestAction id='requestAction' requestParameter='param'>
      <xvw:requestActionValue id='requestActionV1' value='option1' serverAction='#{viewBean.request}' />
</xvw:requestAction>

For the example above, when the url like this

my_url?param=option1

is submitted, the component runs the viewBean.request
