使用 Worklight JSON Store 时面临的问题

Question

我是 Worklight Studio 的新手，正在尝试使用 JSON Store。面对错误信息

Uncaught TypeError: Object # has no method 'exec'

var globalPID = [ {
    "start_date" : "\/Date(1341212400000-0700)\/",
    "PID" : "96052",
    "project_name" : "Copy and Print Microsite Implementation"      
}]; 

var searchFields = { PID: 'integer', project_name: 'string' };
var addSearchFields = { Probability : 'integer' };
var options = {onSuccess: win, onFailure: fail};
var pidCollection = WL.JSONStore.initCollection('globalPIDs', searchFields, options);
pidCollection.store(globalPID,options);

LogCat 中的消息：

在 Cordova 准备就绪后调用 JSONStore 代码（在 wlCommonInit 内部或之后执行）。
