Property value getting null in beforeRenderResponse

Hi,
I have a project with a JSF page containing the <f:phaseListener> tag with its binding attribute equal to its own backing bean , which means the Page's Backing Bean is a PhaseListener.

Now there is a beforeRenderResponse() method implemented in the backing bean which gets called just before the before the RENDER_RESPONSE phase gets executed.

As well as there is a String Property str(initiallly str= null). Its value is set in an action method bound to a <h:commandButton> on the page(this would take place in Invoke application phase - before the Render Response phase) ,
to a String as following .

str=" myvalue";

But when I try to print the value of str in beforeRenderResponse() It comes out to be null. Where does the value of str get changed if no new bean instance is created??
 
It is sorta covered in the JavaRanch Style Guide.
