Note that it's not restoring any (of mine) RequestVars I'm after, but
maybe Lift uses RequestVars internally to hold some internal state it
then uses to look-up snippet-invications?

Snippets are stored in an internal RequestVar so if you snapshot the RequestVars (the generateSnapshotRestorer() method snapshots *all* requestvars) then you'll get the snippets.
 

I updated github (in file ProjectSnippet) with code like the above, with
no luck. The snippet-instance is re-used once I try to re-edit an
already edited project (without reloading the page).

Right... aren't you trying to reuse the snippet?

The overall goal is to create new snippet-instances (backing the dialog) *only* when one clicks "New project" or "Edit" on the base page (the page showing the list). Once the dialog is shown I want to reuse the snippet backing it (for validation etc.), but I don't want that instance re-used after closing/saving.

To be more precise: I only want to re-use the snippet backing the dialog (ProjectEditSnippet) when I perform operations "inside" the dialog. This works fine, but after saving, the snippet backing the dialog performs the callback (stored in projectUpdatedCallbackFuncVar, set by another snippet, ProjectSnippet), which re-renders the "Edit-link" and "modified" in the list, the "Edit"-link is rendered in a way that makes Lift reuse the previous snippet-instance, which I don't want.
