APAR status
Closed as program error.

Error description
JSF is thrown a java.lang.NullPointerException for parsing JSF
Expression Language (EL) expressions. The stack trace is as
follow:

 java.lang.NullPointerException
  at
com.sun.faces.el.MixedELValueParser.getNextToken(MixedELValuePar
ser.java
:140)
  at
com.sun.faces.el.MixedELValueParser.parse(MixedELValueParser.jav

  at
com.sun.faces.el.MixedELValueBinding.getValue(MixedELValueBindin
g.java:6
1)
  at javax.faces.component.UIOutput.getValue(UIOutput.java:147)

This problem can be reproduced by refreshing any of the
application's JSPs that included a JSF EL expression which
referenced a backing bean object or method.

* PROBLEM DESCRIPTION: A NullPointerException is observed      *
*                      when a Mixed value binding expression   *

* RECOMMENDATION:                                              *
****************************************************************
When a JSF application uses mixed value binding expressions
and the client side state saving method, the responsibility of
restoring the state is delegated to the base default value
binding implementation. But, while saving state a duplicate
local copy was used by the mixed value binding implementation
that had not yet been initialized.  This caused a
NullPointerException later in the request processing lifecycle.
Problem conclusion
The code has changed to allow all mixed value binding
expressions to work with client side state saving by using the
state in the base value binding implementation instead of a
local copy.  Also, the local copies of the state have been
removed from the code for the mixed value binding
implementation.

APAR PK37759 is currently targeted for inclusion in Service
Level (Fix Pack) 6.1.0.9 of WebSphere Application Server V6.1
for z/OS.
