Leonardo Uribe commented on MYFACES-3200:
-----------------------------------------
Thanks for the example. It helped a lot to find out the problem
To reproduce it properly it is necessary to set this param:
<context-param>
<param-name>javax.faces.FACELETS_REFRESH_PERIOD</param-name>
<param-value>-1</param-value>
</context-param>
There are two small bugs:
1. We don't enable PSS when faces-config version is 2.1, only when 2.0 is set.
We need to add that check too.
2. There are some wrappers for ValueExpression/MethodExpression that requires
to implement Externalizable, to be saved and restored correctly.
The good news are if you add this on your web.xml:
<context-param>
<param-name>javax.faces.PARTIAL_STATE_SAVING</param-name>
<param-value>true</param-value>
</context-param>
PSS will be enabled and everything will work well. Thanks a lot for the
examples, they were very useful solving this issue.
