根据Key定位ViewObject中的一行的两种方法

a、通过findByKey()，示例如下：

Number departmentId =

((EmployeesRowImpl)(this.getEmployees().getCurrentRow())).getDepartmentId();

Key keyDepartment = new Key(new Object[] { departmentId } );

/**

* findByKey可以使用ViewObject的自带主键，而findByAltKey可以使用ViewObject的自定义主键

**/

// 第2个参数表示最多返回多少调记录

Row[] departments = this.getDepartments().findByKey(keyDepartment, 1);

// Row[] departments = this.getDepartments().findByAltKey("AltKey", key, -1, true);

if (departments != null && departments.length > 0) {

DepartmentsRowImpl department = (DepartmentsRowImpl)departments0;

}

b、通过ViewObject的getRow()方法：

Number departmentId =

((EmployeesRowImpl)(this.getEmployees().getCurrentRow())).getDepartmentId();

Key keyDepartment = new Key(new Object[] { departmentId });

DepartmentsRowImpl department =

(DepartmentsRowImpl)this.getDepartments().getRow(keyDepartment);

if (department != null) {

}
