1. The method getRequestContext() is undefined for the type IRequestCycle.
The RequestContext doesn't exist anymore. Now we have the Infrastructure
object. Also, in order to support portlets, the Infrastructure object doesn't
give you HttpServletRequest or HttpServletResponse objects, but instead give
you a custom object called WebRequest and WebResponse. If you want a reference
to the actual HttpServletRequest, you can inject it into the page. With
Tapestry annotations, that's done like this:
@InjectObject("service:tapestry.globals.HttpServletRequest")
public abstract HttpServletRequest getRequest();
I'm not sure how to get a reference to the Servlet or ServletConfig, but I'm
reasonably certain that it would be in a similar manner.
2. The method getServiceParameters() is undefined for the type IRequestCycle
IRequestCycle.getServiceParameters() is now
IRequestCycle.getListenerParameters().
3. The method getObject(Class) in the type IBinding is not applicable
for the arguments (String, Class<Browser>)
Retrieval of values from Ibinding objects has been simpllified; you now just
call getObject(), or getObject(Class) if you want to perform an assignability
check. So yeah, calling .getObject(Browser.class) should work just fine.
5. (What happened to 4? :))org.apache.tapestry.event.PageRenderListener; is not
used in TP4
what should I use here?
PageRenderListener was split into PageBeginRenderListener and
PageEndRenderListener.
The information is kind of spread around, so I can understand that it's a bit
hard to find, but there are several pages to look to for this kind of help.
Here are some I found useful:
