InvalidOwnerException在ADF中以编程方式创建主/详细视图对象的行

Question

我有2个viewObjects，Strategy和Objective，两个表之间有一个主/细节关系。我已经创建了两个视图对象之间的关联。

Strategy has primary key strgID, and strgName

和Objective表有

objvID as primary key, strgID as foreign key, and objvName

我将数据作为JSON对象获取，其中有一个策略，下面有许多目标。我需要做的是在策略表中插入一条记录，获取由DBsequence自动生成的ID，并在插入目标表时将此ID用作外键。

我正在尝试使用ViewObjectImpl类以编程方式执行所有操作，这是我的代码：

 AppModuleImpl am = null;

    try {

        am = (AppModuleImpl) Configuration.createRootApplicationModule(AM_DEF_NAME, AM_CONFIG_NAME);


         BpmStrgViewImpl strgView = am.getBpmStrgView1(); // this the master viewobject
        BpmObjvViewImpl objvView = am.getBpmObjvView1(); // this is the detail viewobject

//我遍历了JSON并获得了在主视图对象中插入行所需的值

Row row = strgView.createRow();

        // the StrategyID is DB Sequence

        row.setAttribute("StrgNameAr", json.get("name"));

        strgView.insertRow(row);

现在masterViewObject有1行现在我将插入详细viewObject Rows，这是代码//而json有目标行我将执行以下操作：

         Row row = objvView.createRow(); // The Exceptions Happens at this line exactly 


        // object id is DB Sequence 
        row.setAttribute("strgID" , " the new generated sequence value from the master row " ) ;
        row.setAttribute("objvName", "Value");
        objvView.insertRow(row);
         am.getTransaction().commit();

nd this is the Exception :

Answer 1

我通过以下方式解决了这个问题：

am.getStrgObjvViewLink().setSource(strgView);
am.getStrgObjvViewLink().setDestination(objvView);
