The DOMException is with 1.7.2 SP1. Here is the beginning of the exception when using 1.8 RC2:

23:38:44,356 INFO [MainServlet] Adapting to Push environment.

Sample app demonstrating issue. Uses 1.8 RC2 jars.

The page renders correctly but the exception is thrown in the server logs. I've attempted to add xercesImpl and xml-api but no luck.

This is caused by the simultaneous presence of both JSF 1.2 and MyFaces 1.1.

MyFaces has been specified for initialization through the WAR_BUNDLES_JSF_IMPL parameter, but JSF 1.2 is still on the classpath. ICEfaces automatically detects JSF 1.2 and performs certain operations under that assumption. In this case, JSF 1.1 and 1.2 conflict over the role of the View tag: with JSF 1.1, the View tag is responsible for rendering, but with JSF 1.2, the ViewHandler takes this role. When both JSF 1.2 and JSF 1.1 are present, ICEfaces attempts to render the view twice resulting in the exception (the DOMResponseWriter document has been cleared by the termination of the initial render pass, so is null for the redundant pass driven by JSF 1.2 detection).

Candidate fix is to disable JSF12 detection when MyFaces is detected.
