PM92784: INCONSISTENT RESOLUTION OF THE VARIABLES IN F:AJAX@LISTENER METHODEXPRESSIONS

Fixes are available

APAR status

Closed as program error.

Error description

An inconsistent resolution of the variables in
f:ajax@listener MethodExpressions is observed while resolution
of the same variables in a h:commandLink@action
MethodExpression and a ValueExpression worked as expected.
Generally, it occurs:

1. If the f:ajax tag occurs in a JavaServer Faces(JSF) page
below a ui:include AND
2. If a name referred to in the listener MethodExpression is
redefined by a ui:param passed to said ui:include.

*                  (JSF) MyFaces.                              *
****************************************************************
* PROBLEM DESCRIPTION: Variable resolution in a <f:ajax/>      *
*                      listener attribute can be               *
*                      inconsistent.                           *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
When a <f:ajax/> tag occurs in a JSF page below a
<ui:include/> tag and the name referred to in the listener
MethodExpression is redefined by a <ui:param/> in the
<ui:include/>  the variable could be resolved incorrectly.

Problem conclusion

The following fix was pulled into WebSphere Application Server
from the Apache MyFaces Open Source Community to resolve this
problem:
1) https://issues.apache.org/jira/browse/MYFACES-3246

To enable the new behavior the following context parameter
needs to be set to "true" in the web.xml of the application:

com.ibm.ws.jsf.updateFaceletContextKey(true/false - default)

The fix for this APAR is currently targeted for inclusion in
fix packs 8.0.0.8 and 8.5.5.2.  Please refer to the Recommended
Updates page for delivery information:
