Re: extend UiBinder engine

Hi Joseph and Jens,

I didn't have the time to answer to your comments yesterday. 

 Instead of @RequireRole("superAdmin") you would then use @RequirePermission("canMakePersonToAdmin") . 

It's pretty the same: my issue is that I cannot group widgets under the same umbrella : nothing says that is a profile "pizzayolo" will have access to button A and B in a given solution implementation, the buttons A and B will not be able to be accessed by the same profile for a second implementation, each will require an independent condition. So I need a per widget granularity of permissions.

Hi Joseph, 

 the same widget is retained in the DOM and reused many times for the sake of speed and conserving memory.

this is not an issue since a user who doesn't have rights will consume less resources anyway. If he loggs in as a different profile with more permissions, the widgets will be created eagerly and conserved (this is the job of the ClientFactory which indirectly delegates the call to the UiBinder, so it is easy to invalidate widgets on logout, or completely reload the page)

Thanks again for your answers

Hi all,

I have a special need in authorization where I want to control if UiBinder will create or not a widget (I could use visibility visible={roles.admin} in my widgets but I want a smarter solution).

I'd like to use the info in ui:field at template parsing and decide whether the field should be created or not: a central singleton will say if yes or no, that element should be created.

So is there an extension point where I can centrally intercept the internal widget factory?

If the idea is not clear, I'd like to extend a GWT class where I could have a method somehow like

 public  void createWidget( Class widgetClass, Widget parent, String uiField ) 

then rebind the default factory interface with mine in the module definition.
