[flexcoders] Handling serverside error on assemblers method (with data Management services)

[fabio_sebastiano]

Hi, i would like to know how i can intercept and throw server side
errors and show the message on client side.
I'm using several assemblers and, actually, i just catch the error
thrown by the method and throw a generic "DataServiceException" in
this way:

 public void deleteItem(Object prevVers){
        try{
            tributiService.deleteSchedaImposta((SchedaImposta)prevVers);
        }catch (Exception e){
            e.printStackTrace();
            throw new DataServiceException();
        }
    }

But, when an error occur on that method, the fault.string is empty.
Any suggestion?

Thank you very much
