Hello everybody,
Hi!
i had a problem trying to use the tapestr5 IoC from tapestry 4 pages,
its a big system whit tpaestry5 and tapestry 4 pages, when i call a
service that handles the request (org.apache.tapestry5.services.Request)
from tapestry5 pages everything is ok, but when i call this service from
a tapestry4 page i get a java.lang.RuntimeException, everithing is ok
but when the service call some method from the request i get this error.
I guess this happens because Request is a shadow service: actually, when
you use an injected instance of it, you're calling
RequestGlobals.getRequest(). This method returns a Request instance set
during Tapestry 5 request processing. Whan a request is handled by
Tapestry 4, RequestGlobal, which is a perthread service, doesn't have the
Request set, then you have your exception. One possible solution is to
invoke RequestGlobals.storeRequestResponse(Request request, Response
response) yourself before Request is used.
