On my quest to write the support of the JSF 2 client behavior support,
I ran across a problem with the Trinidad render kit and JSF 2. In JSF
2, the ConfigManager starts the call chain for configuring faces
elements when the faces context is parsed. The render kit is
org.apache.myfaces.trinidadinternal.renderkit.RenderKitDecorator and
it relies on using the Trinidad RequestContext to get a
getApplicationScopedConcurrentMap to store the render kit in. The
problem I am having is the RequestContext is setup by the global
configurator which seems to be initializing the contexts when the
request is processed. Since the config manager runs before the global
configurator is processed, the request context is not available to get
the map.
I am not as familiar with this area of our framework and do not feel
confident making changes to fix this issue. We need to somehow be able
to instantiate the RenderKit instance when the ConfigManager runs, not
when the request is processed. I am not sure if we want to relocate
the code from RequestContext to a non-request based object or make
changes to the configurator to setup the information during faces
config parsing and not upon the request processing.
Ideas?
Thanks,
Andrew
PS - here is the stack trace so you can see when the call is taking
place (Ignore the line in the RenderKitDecorator as I have tried some
changes):
