Hi,
Looking over your code again I just noticed something's amiss. Where's
the Java code for the Layout class? You seem to have posted the
InnerLayout class twice.
Anyhow, I think I've figured out what's really going on. Your using
InjectContainer in Layout, but that doesn't inject the page, it injects
the InnerLayout. This, of course, fails.
A potential solution would be to use ComponentResources#getPage to get
your page in a getter and just use that in your layout.

Hi,
Your BasePage should be in the base subpackage, that's test.base in your
case. What happens is that Tapestry tries to cast BasePage to Component,
which fails because it hasn't been enhanced by Tapestry - this only
happens for components in the base, components, and page subpackages.
That's my (more or less informed) guess having checked the source of
InjectContainerWorker, anyhow.

Hi
I'm getting the following exception:
Component TestPage:innerlayout is not assignable to field
test.components.Layout.page (of type test.BasePage).
The skeletons for my components are below. Essentially, my page has an
(inner) layout, which in turn has an (outer) layout. I try to inject the
page into both (inner and outer) layouts.
The page is successfully injected into the inner layout, but the outer
fails. @InjectContainer seems to be selecting the wrong component in
this
case. It makes no difference if I remove the injection for the inner
layout
(so it doesn't seem to be a conflict).
Should this work?
