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

In general the hash fragment the GWT places framework generates consists of two parts: a unique prefix that represents the place type and a token that contains the serialized state of a place instance. Both are separated by a colon.

You can use @Prefix to change the default unique prefix of a Place which is the concrete Place class simple name, e.g. CustomerPlace.

To fill a Hyperlink target history token you would use the PlaceHistoryMapper.getToken(new CustomerPlace(<optional state>)) method which basically returns Prefix + ":" + tokenizer.getToken(place) .

If you don't like the colon you can also use your own logic by either implementing the PlaceHistoryMapper interface yourself or by creating just a single PlaceTokenizer<Place> with a prefix @Prefix(""). This tokenizer will act as a catch-all tokenizer and you can then freely implement your getToken() / getPlace() logic for all places inside that tokenizer. The catch-all tokenizer is kind of a cheat, so I would prefer implementing PlaceHistoryMapper directly. 

For example my apps usually use history tokens that look like /#!/archive/2014/august/
