Question

我正在使用MF 6.3.0.00.20150204-0610并使用混合应用程序。我在应用程序中添加了JSONStore，可以在applicaiton-descriptor.xml中清楚地看到它。但是，当我尝试使用该功能时：

def = WL.JSONStore.init("people").done(function() {
    console.log("Ok, I think I did the store?");
});

我在控制台中收到此错误：

错误：无法调用WL.JSONStore.init，因为应用程序中缺少JSONStore。将JSONStore添加到应用程序描述符，重建并部署它。

我现在已经多次重建和部署 - 多次。

Answer 1

这是我做了什么，然后通过成功消息获得提醒：

创建了一个新的项目和应用程序，添加了iPhone环境
添加了JSONStore功能（来自应用程序描述符设计视图）

共同的\ js \ main.js：

var def;

function wlCommonInit(){
    def = WL.JSONStore.init("people").done(function() {
        alert("store created");
    }); 
}

右键单击iphone文件夹，然后选择Run As＆gt; Xcode项目
在XCode的iOS模拟器中运行应用
得到以下提醒

我想问题应该是 - 你是如何初始化JSONStore的？

我刚尝试使用MFP CLI并让它正常工作。这是我的个人设置：

JDK 1.7和$ JAVA_HOME设置（MFP尚不支持1.8）
MFP CLI版本6.3.0.00.20150204-0610（mfp -v）
使用git在步骤中显示已更改的文件，添加功能，构建和部署
使用MFP Tutorial JSONStore – JavaScript API

在终端

    $ javac -version

    javac 1.7.0_72

    $ echo $JAVA_HOME

    /Library/Java/JavaVirtualMachines/jdk1.7.0_72.jdk/Contents/Home

    $ mfp -v

    6.3.0.00.20150204-0610
