beforePhase in interface javax.faces.event.PhaseListener

writeCodeBeforeBodyEnd

public static void writeCodeBeforeBodyEnd(javax.faces.context.FacesContext facesContext)
                                   throws IOException

In case of StreamingAddResource and a documentBody-Tag, this method will be called with the normal response writer set. It will directly render out the javascript-text at the current position (immediately before body-closing). In the case of DefaultAddResource, this method will be called with a wrapped response writer - and we'll buffer the javascript-text in the request, for the ExtensionFilter to catch and render it.

Parameters:

facesContext - The current faces-context.

Throws:

IOException - Exception if writing to the output-stream fails.
