Re: extend UiBinder engine

@RequiresRole("superAdmin")

@UiField

CheckBox makeAdmin 

this code is too specific for me: I'm creating a CMS and I cannot attach hardcoded roles to my fields: each solution will make its own decision on what fields are allowed for which profile.

Well ok. A CMS is permission based because users of your CMS can create their own roles. Instead of @RequireRole("superAdmin") you would then use @RequirePermission("canMakePersonToAdmin") . Then you check if a user has the permission.

We do the same for one of our apps. All permissions (the effective permissions as a user can have multiple roles defined by our customers) are embedded in our index.html file as JSON. The app loads this JSON and then has a userSession.hasPermission(<string / enum>) to get the information. Then you only have to generate the glue code for configuring the view.

So this approach is possible for both situations: static roles or dynamic roles that pull in permissions of a static set of permissions defined by the app.
