Breeze.js How to display Validation Error Message

during Save changes, there are instance when validation is failing, but how do i get back and display the actual Error Message. The saveFailed function is executed, but i want more details information, about what validations failed and those individual error emssages

 function saveChanges() {
       if (manager.hasChanges()) {
           manager.saveChanges()
               .then(saveSucceeded)
               .fail(saveFailed);
       } else {
           alert("Nothing to save");
       };
   };


   function saveSucceeded() {
       alert("changes saved successfully");
   };

   function saveFailed(error) {
       alert("Error while saving changes" + error.message);
   };

Have a look at the TODO sample that is provided with the breeze download.

The dataservice.js clearly shows you how to catch and display validation errors.

The 'error' object returned by the fail handler, should contain additional details, depending on the error. The following properties should always be there

error.message - the error message error.status - http error code - usually a 400 or 500 code error.detail - any details relevant to the error error.XHR - the raw XML HttpResponse object error.responseText

For validation errors, right now they appear in the error.message, but we are looking at breaking them out in a cleaner fashion, possibly into another property. But for now they will appear in the error.message.
