I am a bit confused now. I follow the example: https://developers.google.com/web-toolkit/doc/latest/tutorial/i18n As I understand the GWT.create should create proper implementation

The issue is that they would need to integrate these messages with their translation system, but they don't have the hooks to do so. For example, there is no @Generate notation here, and no way to put one appropriate for whatever they are doing with translations. They can't specify MD5 keys or some other key that won't collide with what they have elsewhere in their app. It is possible to supply the translations anyway, but they will have to know about it themselves and do something different than every other message in the app.
Problem with passing an instance of this is that it's practically an
inner class
of CellTree, so I would have to allow passing this interface to
CellTree - is
that expected? How does GWT handle more complicated widgets?
AFAIK, there aren't any other widgets that need translations. Basically, either the widget should be self-contained, which means it has all the translations for all supported languages, or it needs to allow the caller to pass in the messages to use. You can leave a helper method without Messages that just GWT.creates it and hopes for the best (hopefully only used by people that aren't localizing their app). For example, the caller could create an empty extension of the Messages interface (which would need to be moved so it could be accessed) and add their own @Generate* annotations on it as needed to tie into their translation system, and then GWT.create it themselves when creating the widget. http://gwt-code-reviews.appspot.com/1739803/ -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
