OAF的TABLE中的LOV依赖

经常在一个页面中出现在一个table展示过程中,对其中的一列(LOV)进行修改,此LOV依赖于另一列(lov或text)

效果

结构图

• DepartmentVO和EmpVO为两列LOV的VO
• DeptLovRN.xml和EmpLovRN.xml是外部LOV的Region
• TableVO为最终显示页中的VO

        OAViewObjectImpl vo = (OAViewObjectImpl)am.findViewObject("TableVO");
        if (!vo.isExecuted()) {
            vo.executeQuery();
