title: Method call to bind a bean parameter
body: <p>A manage bean is configured in a bounded task flow as pageflow scope and in that taskflow I have a method call.The method needs a string as input and I wanna bind the value with a parameter in the  bean.
  While doing that i.e making the EL I cannot find any bean in ADF Manage Bean. 
  I have tried with different scope like request,backing bean,session,etc but none works.
  Any solution u can suggest??? </p>
