Hide columns in JClient in function to BC4J Entity

Question

Hi:
I need to hide some columns dynamically in my JClient Panel in base to conditional BC4J Entity object bussiness rule.
For example if i put my pseudocode in Oracle Forms based (i don't remeber the syntaxis well): "if my Deparment.idDepartment = 1000 then....Hide the Employee.Salary".
Now, in JDeveloper, in my 'DepartmentImpl.java' put the condition, but i know, i can't write code to hide the column in runtime mode here. I need to do that in JClient.
How can i do this, passing a parameter between BC4J and JClient?
Regards

Shailesh:
The code not works well for me. I try to explain my requieriment:
I have a field named "Capturahoras". If "Capturahoras" is equal to "S" then, enabled mHorastrabajados, otherwise, disabled mHorastrabajados.
My "Idconepto" is my PK and when i selected another value for my PK, my field "Capturahoras" should be changed to "S" or "N" (Yes or Not).
Sorry, but i'm not an expert for JDev and some months ago i have been programming in Oracle Forms.
I put my code here but not works well:
