[xwiki-dev] [Proposal] New generic Action for calling an API and returning the result as XML

[Vincent Massol]

I talked briefly to ludovic and he says we could reuse our GWT API.  
We would need some wrappers in order to be able to call it directly  
(for the serialization for example). That would allow us to focus on  
having one AJAX API.
