你好上午还挺新的，使用JayData和OData的，所以请原谅我的无知。
这是我的对象结构：
$data.Entity.extend('PlannerModel.vMasterPlanner', {
'Sequence_Number': { key:true,type:'Edm.Int32',nullable:false,required:true },
'Scenario_Name': { type:'Edm.String',nullable:true,maxLength:250 },
'Activity_ID': { type:'Edm.String',nullable:false,required:true,maxLength:250 },
'Activity_Description': { type:'Edm.String',nullable:true,maxLength:500 },
'Object_ID': { type:'Edm.String',nullable:true,maxLength:250 },
'Object_Description': { type:'Edm.String',nullable:true,maxLength:400 },
'Operation_Code': { type:'Edm.String',nullable:false,required:true,maxLength:250 },
'Operation_Description': { type:'Edm.String',nullable:true,maxLength:50 },
'Crew_ID': { type:'Edm.String',nullable:true,maxLength:250 },
'Crew_Name': { type:'Edm.String',nullable:true,maxLength:50 },
'Period': { type:'Edm.Int32',nullable:true },
'vActivity': { type:'PlannerModel.vActivity',required:true,inverseProperty:'vMasterPlanners' } });
$data.Entity.extend('PlannerModel.vActivity', {
'Activity_ID': { key:true,type:'Edm.String',nullable:false,computed:true },
'Activity_Name': { type:'Edm.String',nullable:false,required:true },
'vMasterPlanners': { type:'Array',elementType:'PlannerModel.vMasterPlanner',inverseProperty:'vActivity' } });
$data.EntityContext.extend('PlannerServiceLibrary.PlannerEntities', {
ProgressDetails: { type: $data.EntitySet, elementType: PlannerModel.ProgressDetails },
ProgressHeaders: { type: $data.EntitySet, elementType: PlannerModel.ProgressHeader },
vCrews: { type: $data.EntitySet, elementType: PlannerModel.vCrew },
vPeriods: { type: $data.EntitySet, elementType: PlannerModel.vPeriod },
vOperations: { type: $data.EntitySet, elementType: PlannerModel.vOperation },
vActivities: { type: $data.EntitySet, elementType: PlannerModel.vActivity },
vMasterPlanners: { type: $data.EntitySet, elementType: PlannerModel.vMasterPlanner } });
只是一个小的解释：表万事达规划器是一个详细表和表活性是标题表我需要选择所有从活动表中的活动（标题），其中，其在例如详细表实测值= 2如何船员ID我这样做的OData使用和JayData
我目前使用
provider.vActivities.filter(function (ac) {
return ac.vMasterPlanners.Crew_ID == "FM2_F/W" })
.toArray(function (e) {
console.log(e);
});
这是误差未知表达类型来处理：EntitySetExpression本地主机/移动网络/ htdocs中/资产/ jayData / jaydata.js 89线
请帮助任何人！
谢谢 ！
