Hi Matthias, hi Edmond,
I was facing the same error (during initialization of Trinidad) when I tried a
simple example last weekend.
I could track it down to the following:
During Context-Initialization (ContextServletListener) MyFaces uses a fake
Proxy (org.apache.myfaces.application._SystemEventServletRequest) for
HttpRequest.
This proxy returns
java.lang.UnsupportedOperationException: This request class is an empty
placeholder
regardless which method is invoked.
On the other hand Trinidad tries to detect if this request is a partial request.
This detection wants to read request header "Tr-XHR-Message".
org.apache.myfaces.trinidadinternal.renderkit.core.CoreRenderKit.isAjaxRequest(CoreRenderKit.java:148)
at
org.apache.myfaces.trinidadinternal.renderkit.core.CoreRenderKit.isPartialRequest(CoreRenderKit.java:163)
at
org.apache.myfaces.trinidadinternal.config.xmlHttp.XmlHttpConfigurator.getExternalContext(XmlHttpConfigurator.java:61)
at
org.apache.myfaces.trinidadinternal.config.GlobalConfiguratorImpl.getExternalContext(GlobalConfiguratorImpl.java:351)
at
org.apache.myfaces.trinidadinternal.context.FacesContextFactoryImpl$CacheRenderKit.<init>(FacesContextFactoryImpl.java:90)
I don’t really know who is using the wrong assumptions.
Should the MyFaces HttpRequest-Proxy allow method invocations like
request.getHeader("Tr-XHR-Message ")?
Or should Trinidad not try to read any request values, headers, attributes,
etc. during initialization?
Hopefully this could point you in the right direction.
