Problem in using nested dependent items with jheadstart 1013

Question

Dear JHeadstart Team,
Suppose we We have 3 following tables ( z is child of y and y is child of x) and we have a view object which have joined all 3 tables together. we have
mad a page on this view.
x (
code1 PK
,Name
y ( code2 PK
,x_code
Z ( code3 PK
, y_code2
MyViewObject contains the following fields : z.code3,z.y_code2,y.x_code,y.code2,x.name,x.code
I want that when a user enter a valid value in y_code2 field it automatically retrieve related information of that code and show it. we set "depends on
item property" of x_code ,code2,name ,code1 to y_code2 but when user enters value for y_code2, only code2,x_code get correct value and
code1,name remain null. I also set "depends on item property" of code1,name to code2. I hoped that with changing the value of code2, these field got
correct value but again these fields remained null.
To simplify the situation I removed the x table from view object and add a transient field to view object (which use a database function with this format
getXName (y.x_code) ) but surprisingly enough It did not work either.
These seemed to me something like bug. Am I right? Is there any workaround for these problems ?
What is the best solution for implementing this functionality ?
Best Regards,
Navid
P.S. We are using JHeadsart 10.1.3 Service update 1 and jdeveloper 10.1.3

Dear Steven,
Thank you very much for your paying attention to this matter. I checked the adf bc tester and I realized that when I filled y_code2 only the fields in the y table were automatically updated. To simplify the problem I made a simple project based on the HR schema objects using JHeadstart . I add country and location to department view object and checked it with adf bc tester. I realized that when I enter value in locationId in the department view only location fields are automatically updated and country fields remain null. I also used your techniques in the "What to do when ADF BC Tester does not update the lookup item" section but it does not work either. I think that maybe the normal behavior of ADF is to just fetch only the first level lookup information and ADF does not care to fetch information of lookup of lookup ( I mean nested lookup).
I understand now that my problem is not a JHeadstart related issue however any help,reference or link to implement such functionality would be highly appreciated.

Navid
