How to reference the Parent view Object attribute in Child View object

Question

Hi , I have the requirememt to generate Tree like struture to display Salary from joining date to retirement date in yearly form.I have writtent two Pl/SQL function to return parent node and child nodes(based on selected year).
1.First function --> Input paramter (employee id, retirement date , joining date) --> return parent node row with start_date and end_date
2. 2nd function --> input paarmter(employee id, startDate, end_date) --> return child node based on selected parent node i.e. start date and end date
I have created two ADF view object based on two function return
Parent Node --> select * from Table( EUPS.FN_GET_CONTR_SAL_BY_YR(employeeId,retirement Date, dateOf joining)) ;
Child Node --> select * FROM TABLE( EUPS.FN_GET_CONTR_SAL_FOR_YEAR( employeId,startDate, endDate) ) based on selected parent node.
I am giving binding variable as input for 2nd function (child node) . I don't know how to reference the binding variable value in child view from parent view.
Like I have to refernce employeId,startDate, endDate values in 2nd function from parent view object. some thing like parentNode.selectedStart_date parentNode.employeeId.
I know we can achive this writing the code in backing bean.But i want to know how can we refernce parent view object attribute values in child view object using Groovy or otherway?
I will appreciate your help.

I have two view com.ContractualSalaryByYearlyView for Parent Node and com.ContractualSalaryByYearlyView for child Node.
I have created view link(ContractualSalYearlyByYearViewLink) betweem two view by giving common field empId, stDate , endDate.(below is the view link xml file).
I tried give the binding attribute values using parent object reference like below in com.ContractualSalaryByYearlyView xml file but getting error
Variable ContractualSalaryByYearlyView not recognized.I think i am using groovy expression.
