Subject Re: spring context troubles
Date Mon, 29 Dec 2008 23:41:01 GMT
This is a change in behavior from Tapestry 5.0; it was necessary in
order to coordinate Spring and Tapestry IoC.  It is necessary to let
Tapestry initialize Spring and use Tapestry-specific subclasses of
XmlWebApplicationContext and DefaultListableBeanFactory, to hook in
the logic that allows Spring beans to use @Inject and @InjectService.

You should be fine if you just remove the ContextLoaderListener from
your web.xml.
