Yep, I apologise. The from-action quoted below is indeed valid.
This is *not* actually an EL-expression, though; just compared literally
with the actionListener property of the command component that was used
to generate the outcome. See class ActionListenerImpl: it just stores
the value of methodBinding.getExpressionString() before it invokes the
methodBinding so that literal string can later be used to select the
matching navigation rule using the from-action clause.
Still seems weird - particularly when the t:aliasBean concept is
factored in! As Mike says, it's probably a feature to avoid. For example
it's pretty ugly for a rename of the action method to invalidate a
navigation rule...
Using from-view-id and from-outcome should be sufficient, and more stable.

It is legal, and it is the correct syntax.
However, I don't understand the usage. from-outcome seems like it's
a "push" to a page. from-action appears to be a "pull" to a page. I
don't see how these can coexist.
In any case, Mick, I don't think I'd recommend using from-action.
It's certainly not the norm, and I think it's going to double-process
your #{ userBackingBean.prepareForEdit} method, once when you trigger
the action with the button, and again when you navigate to the user
detail page.

By the way,
I don't think this is legal:
<from-action>#{ userBackingBean.prepareForEdit}</from-action>
If it is legal, I doubt that's the correct syntax.
