Hi. I tried the new functionality. Step 1 works: In my edit client link
function I call S.setSnippetForClass("Clients", editSnippet) and it brings up
the page, using the correct snippet.
Now the editing page has a submit button, "Duplicate", which for testing
purposes I commented out its function to do nothing. When the snippet has been
instantiated by Lift internally, clicking Duplicate correctly reuses the
snippet when it reloads the page. However when the snippet was pre-registered
using S.setSnippetForClass, the submit button causes a new snippet to be
instantiated for the reload. Even registerThisSnippet doesn't work -- it's
necessary to call setSnippetForClass in the submit function. Not that that's
such a big deal but it's probably not the intended behavior.
So in short, S.setSnippetForClass works but doesn't survive a reload via a
submit button, nor does registerThisSnippet extend its lifetime.
Thanks.

I opened a ticket for this. I'll expose functionality so you can register
stateful snippets as part of the request process.
