TABLE中动态设置poplist的值跟着当前行的某些列动态变化

核心方法

 OAAdvancedTableBean table = (OAAdvancedTableBean)webBean.findChildRecursive("TimeEntryTbl");     
 OAMessageChoiceBean elePoplist = (OAMessageChoiceBean)table.findChildRecursive("ElementSelect");     
 elePoplist.setListVOBoundContainerColumn(0, table, "EmployeeGroupName");     
 elePoplist.setListVOBoundContainerColumn(1, table, "PeriodEndDate");     
 elePoplist.setListVOBoundContainerColumn(2, table, "AssignmentId");     
 elePoplist.setPickListCacheEnabled(false); 

问题扩展。

在页面中有添加新一行的操作，如何使添加的新一行中的poplist的值集跟着当前行的LOV返回的值变化而变化。

核心思路：

在MessageChoice中绑定poplist取值来源的时候不要使用dependent poplist，而是使用View Instance。

有些关联list是需要上下文限制的，如 省市选择，甚至还是在table中。2个poplist通过pvo实例化，在根据事件，刷新VO是不行的，因为是多行，而且局部事件是早于poplist数值获取的，这样也没办法加限制条件。【摘自oraclearea51 的Sudhakar Mani文章】
