Not sure if this is this a MyFaces issue, but as I don't remember having it
when my projects were running with with Mojarra, I'd like to see if you can
help me.
I'm eventually seeing this exception in my Tomcat 7.0.47 log:
java.lang.IllegalStateException: Cannot change buffer size after data

It happens in different pages, but since the exception doesn't happen in
any of my managed beans, I have no idea of what is happening.
Currently I'm using MyFaces 2.2.4, but this was happening with previous
2.2.x releases too.
Any ideas?
Thanks in advance.
