Grailsでparamsを使用してJSONオブジェクトを取得する

Question

Grailsの初心者です。 。小さなgitchしかしかもしれないその私がテストしたい私の最初のいくつかのデータフローのための障害で作成

私のjQueryのコール：

var jsonObjects = [{name: "IPAD", input: "IPAD", program: "IPAD", destination: "IPAD",  
priority: "IPAD", userData: "IPAD", email: "IPAD", webCallBackURL: "IPAD", copyToLocal:  
"IPAD", scriptPreProcess: "IPAD", deleteSource: "IPAD", moveToSource: "IPAD",  
scriptPostProcess: "IPAD", inputImage: "IPAD", leftImage: "IPAD", topImage: "IPAD", 
opacityImage: "IPAD", bImageAdAvBlanking: "IPAD"}] 

$.ajax({ 
    type: "POST", 
    url: 'http://localhost:8080/Medusa/jobControlREST/save', 
    data: {ipad: JSON.stringify(jsonObjects)}, 
    contentType: "application/json; charset=utf-8", 
    dataType: "json", 
    beforeSend: function(x) { 
     if (x && x.overrideMimeType) { 
      x.overrideMimeType("application/json;charset=UTF-8?"); 
     } 
    }, 
    success: function() { 
     alert('hi'); 
    } 
}); 

私のGrails：

def save = { 
    def jsonString = params['ipad'] //returns null 
    def json = JSON.parse(jsonString) // returns null obviously 
    println "this is POST call" +json // gets printed but json is null...sign ( 
} 

urlmapping: 
    "/$controller/$action?/$id?"(parseRequest:true) { 
     constraints { 
      action = [GET:"index", POST:"save", PUT:"update", DELETE:"remove"] 
     } 
    }
