i see error coming myfaces2, jsf implementation default websphere 8.5, tried implement mojarra 2.1.13 shared lib did not work (i followed steps ibm docs).

the other odd thing app rendered main page when rendering error shows up.

• does know error?

piero,

to resolve problem, add or replace following context parameter in web.xml file , republish project.

<context-param> <param-name>javax.faces.partial_state_saving</param-name> <param-value>false</param-value> </context-param> 

that because using default jsf implementation (myfaces) , have developed in mojarra, need set in order work myfaces.
