Re: Is there a tutorial that explains Places and Hyperlinks?

Actually everything you have asked is covered in http://www.gwtproject.org/doc/latest/DevGuideMvpActivitiesAndPlaces.html

- The URL representation of a Place is described in "Places" section (Prefix + ":" + token)

- The @Prefix is mentioned in "PlaceHistoryMapper" section and obviously you want to use it if you don't like the default prefix chosen by GWT (the Place class name)

- How to get a token for a Hyperlink is covered in section "How to navigate" (using the PlaceHistoryMapper.getToken() method)

So maybe you just need to read documentation a bit more carefully ;-)

Perhaps.  Maybe you can explain where my reading is going astray.  For instance:

" For more control of the PlaceHistoryMapper, you can use the @Prefix annotation on a PlaceTokenizer to change the first part of the URL associated with the Place. For even more control, you can instead implement PlaceHistoryMapperWithFactory and provide a TokenizerFactory that, in turn, provides individual PlaceTokenizers."

That says I can use @Prefix, but it doesn't say why I would want to, how I would use it, or how it gives me more control of the PlaceHistoryMapper.

And you're right, it does say I can call PlaceHistoryMapper.getToken() to get a token for a Hyperlink, but my Hyperlinks are laid out in UI Binder.  There's no option to invoke PlaceHistoryMapper.getToken() there.  The examples I can find for Hyperlink show tokens with no colons in them.  I only figured out I needed a colon in there by reading the source code for AbstractPlaceHistoryMapper.getPlace().
