ProxyPlace: converting a token to EntityProxy

[Y2i]

I'd like to implement something similar to non-existent ProxyPlace:
http://google-web-toolkit.googlecode.com/svn/javadoc/2.1/index.html?com/google/gwt/app/place/ProxyPlace.html

Is there a standard way to convert a token to a sub-class of
EntityProxy in PlaceTokenizer<P>.getPlace(String token)?
Should I use my own sub-class of AbstractPlaceHistoryMapper<F> instead
of combination of PlaceTokenizer<P> and PlaceHistoryMapper?
If AbstractPlaceHistoryMapper<F> is the best alternative, what would
be the best candidate for a token? Should it be a string
representation of Entity's ID or something else?

Your thoughts will be greatly appreciated!

RequestFactory#getProxyId
http://google-web-toolkit.googlecode.com/svn/javadoc/2.1/com/google/gwt/requestfactory/shared/RequestFactory.html#getProxyId(java.lang.String)
(if you used getHistoryToken to generate the token, of course)

No, you have to create a PlaceTokenizer for the ProxyPlace, which
you'll initialize with a RequestFactory instance (which means you have
to use PlaceHistoryMapperWithFactory with a method in your factory
creating the PlaceTokenizer with the RequestFactory)

You can actually find the code for ProxyPlace et al. if you go back in
history in the SVN repository.
(or download GWT 2.1 M3 for example, which contained them)
