but this seems really really flaky, undeterministic and appserver
dependent..
If you really want to create a SpringContext/TapestryIoC love child :)
could you create a new ContextLoaderListener to replace spring's that
does what you want?
So that both the SpringContext and TapestryIoC are loaded properly
before anything else (servlets, filters, etc)??
Or again, can you have the feature you're adding be backward compatible
and not require changes to the way people load up their spring
context... (though i know the new feature would be turned off at that
point).

We need to figure out the order that the filters are initialized, so
that the Tapestry filter can be initialized first. I think just
listing it first in the web.xml may do the trick.

I just tried it, and it won't work like that :(
Like I said, I use spring outside of tapestry. So I need a valid working
spring context before the first request ever gets to tapestry filter..
Here is my exception when I comment out the normal ContextLoaderListener..

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.
