Facelets EL functions do not work after form submit (both normal and ajax). It 
is certainly classloading problem - org.apache.el tries to load EL function 
impl. class but there is no appropriate classloader. I studied JBoss 
classloading model and probed various configurations - without result.

Environment:

  | JBoss Seam 1.2.1.GA
  | JBoss AS 4.2.0.GA
  | JSF 1.2 (Sun) 1.2_04
  | Facelets 1.1.12
  | Ajax4jsf 1.1.1
  | Richfaces 3.0.1
