Hi Alex, I've filed TOMEE-2757 for the serializer issue you identified during the vote. Can you identify where in your classpath this is being picked up: org.apache.xalan.processor.TransformerFactoryImpl?
It isn't included in 7.1.2 TomEE release - are you including Xalan in your application? This should be using the javax.xml.transform.TransformerFactory mechanism: https://github.com/apache/myfaces/blob/2.2.x/impl/src/main/java/org/apache/myfaces/config/DefaultFacesConfigurationProvider.java#L521 - so if you have Xalan in your application you should be able to either remove it, or add serializer to your application. Just building some snapshots for you to test against. Jon
