Re: RenderSupport in pages?
The fact that you can @Inject RenderSupport as well as use @Environmental is something explicitly set up in TapestryModule, to allow non-components access to RenderSupport. The service's implementation simply gets the RenderSupport from the Environment and delegates all method invocations to it.

Hi Piero In this case it seems that Tapestry doesn't like it when you use @PageLoaded or @PageAttached, though I can't explain why this wouldn't work... > It is an abstract class - but that shouldn't matter? No, not at all I have done this too. I don't know what to make of the docs, they seem a bit conflicting: "The Environmental annotation only works inside components." well this is not true, I am using it in pages without problems. @Environmental works per request, and so does @PageAttached and @PageLoaded, so it is a bit of a puzzle... although these are not really the render phase methods with which RenderSupport is best suited for. regards, Peter - Original Message - From: "Piero Sartini" To: "Tapestry users" Sent: Friday, 19 June, 2009 14:27:59 GMT +02:00 Athens, Beirut, Bucharest, Istanbul Subject: Re: RenderSupport in pages?

Nope.. as soon as I try to access the RenderSupport in pageAttached or pageLoaded. It is an abstract class - but that shouldn't matter? The Page has some AJAX event handlers as well.. maybe that's the problem? I now ended up creating a helper component called RenderMyStyle which is included in the template.

Re: RenderSupport in pages?
You don't have access to the RenderSupport environmental until the page is actually rendering. So it's available between the setupRender and cleanupRender phases, but outside of that (i.e in your pageAttached/pageDetached phases) it has not been placed in the environment yet.
