我有问题过滤基于选择另一个CB的CB。我做错了什么/错过了什么?请帮帮忙。我有第一个CB，它得到银行名称，这个CB根据先前CB的选择，即银行，获得银行分支机构。现在，当用户选择银行名称时，我要过滤第二个CB，即银行分行，仅显示该银行的相关分支。

我有这个BankDS.ds.xml，第一个CB用来填充银行CB，我有第二个BankBranchDS.ds.xml(代码如下所示)，它填充了银行支行CB。

我正在使用这个版本的SmartClient版本: v8.3p_2014-04- 23 /PowerEdition部署(构建于2014-04-23)，并在火狐浏览器版本23上进行测试。

这是我的DSRequest输出

{

operationType:"fetch", 
componentId:"isc_PickListMenu_10", 
data:{
    fieldName:"bankid", 
    operator:"equals", 
    value:1
}, 
startRow:0, 
endRow:75, 
textMatchStyle:"startsWith", 
resultSet:[ResultSet ID:isc_ResultSet_11 (created by: isc_PickListMenu_10)],

    caller:[ResultSet ID:isc_ResultSet_11 (created by: isc_PickListMenu_10)], 
    methodName:"fetchRemoteDataReply"
}, 
willHandleError:true, 
showPrompt:false, 
prompt:"Finding Records that match your criteria...", 
oldValues:{
    fieldName:"bankid", 
    operator:"equals", 
    value:1
}, 
requestId:"BankBranchDS$62712", 
internalClientContext:{
    requestIndex:{
        Class:"Number", 
        formatter:"toString", 
        localeStringFormatter:"toString", 
        localeProperties:Obj
    }
}, 
fallbackToEval:false, 
bypassCache:true
}

这是我的响应输出

这是我的ComboxItem代码

    bankBranchName = new CustomComboBoxItem()
    {
        protected Criteria getPickListFilterCriteria()
        {
            Integer bankid = (Integer) bankName.getValue();
            AdvancedCriteria criteria = new AdvancedCriteria("bankid", OperatorId.EQUALS, bankid);
                            return criteria;
        }
    };

我的BankDS.ds.xml看起来像这样
