Hi
I almost forget to say one advice. Please try to remove:
<context-param>
<param-name>org.apache.myfaces.REFRESH_TRANSIENT_BUILD_ON_PSS_PRESERVE_STATE</param-name>
<param-value>true</param-value>
</context-param>
<context-param>
<param-name>org.apache.myfaces.REFRESH_TRANSIENT_BUILD_ON_PSS</param-name>
<param-value>true</param-value>
</context-param>
so org.apache.myfaces.REFRESH_TRANSIENT_BUILD_ON_PSS will set to auto
mode. Recent changes in 2.1.6 / 2.1.7 has improved that part. Maybe
your code will work doing that.
regards,
Leonardo Uribe
