UnsupportedOperationException when rendering 'updates' for the render target on
postback
----------------------------------------------------------------------------------------
Key: TRINIDAD-1649
URL: https://issues.apache.org/jira/browse/TRINIDAD-1649
Project: MyFaces Trinidad
Issue Type: New Feature
Components: Components
Affects Versions: 2.0.0-core
Environment: Running Trinidad 2.0.x; with Facelets; no Partial State
Saving and using JSF Ajax request rather than the Trinidad PPR mechanism
Reporter: Pavitra Subramaniam
1. Download the patch onto your Trinidad 2.0.x branch (minus the ResponseWriter
class changes). Run the page ajaxPPRDemos.jspx. Click on the "Partial Submit"
button which posts back to the server using the JSF Ajax communication channel
rather than the trinidad. Notice the UnsupportedOperationException.

2. It looks like JSF 2.0 added new methods startCDATA() and endCDATA() methods,
which need to be used by the trinidad ResponseWriterDecorator and other
implemetations of ResponseWriter.
3. the ReponseWriter fixes patch makes the following fixes:
ResponseWriterDecorator.java (now extends ResponseWriterWrapper. Ideally we
should remove ResponseWriterDecorator entirely and just use JSF2.0
ResponseWriterWrapper)
HtmlResponseWriter.java (overrides 2 new methods sneakily added to
javax.faces.context.ResponseWriter but never really gives a compilation error).
XmlResponseWriter.java (same as above)
XhtmlResponseWriter.java (-do-)
Note that under normal circumstances these exceptions are not seen. Only when
testing with JSF 2.0 Ajax.
