Rails - Aug 2006 - Named routes and url generation?

Hi all

In my application I''ve some named routes defined this way...

map.label_context1 '':context1/label'', :controller =>
''mycontroller''

map.label_context2 '':context1/:context2/label'', :controller
=> ''mycontroller''

map.label_context3 '':context1/:context2/:context3/label'',
:controller
=> ''mycontroller''

The controller for the 3 routes is the same but obviously it behaves
differently whether 1 or 2 or 3 contexts are given.

The routes and the controller just work fine BUT...

Now, on the same page of my application, I want to generate links for
all the possible levels my controller can act...

I.e. if I''m in context3 I want to provide links to context1, context2
and context3 urls

So I''ve done something like

label_context1_url params
label_context2_url params
label_context3_url params

This code just returns n times the most complete url.

i.e. if I''m in context3 the code above will generate 3 identical urls

:context1/:context2/:context3/label

Can someone explain to me this beahviour?

my opinion is that if the *_url method is overfed with parameters that
exceed the parameters of the named route, the method will fallback on
a standard route generation returning the most complete url.

How can I force the *_url method to generate the url from the given named route?
Or, how can I ask a named route which parameters is able to take, so I
can dynamycally delete the parameters in surplus?

Thanks

Paolo

I''ve found a reply to my question.
My issue is a known problem of named routes which appears to be fixed
in trunk version.
