Is it possible to create bidirectional multiselect tables? Help.

Question

Hey everyone (once again since you are in fact great in helping me out),
I was wondering if it would be possible to create bidirectional multiselect tables to interact to each other, like the behaviour qlikview has, since thats my goal.
Imagine that i have 3 tables in my schema/database:
Departments (from HR schema), with the following attributes: department_id (primary key), department_name, manager_id, location_id;
Salary_by_job (created for this purpose), with the following attributes: job_id (primary key), department_id, salary, min_salary, max_salary;
Employees (from HR schema), with the following attributes: employee_id,......, job_id, salary, manager_id, department_id
Can it be possible to creat bidirectional multiselect tables?
Like the following:
- I click on a department, it shows the data relevant to that department in the salary_by_job table and in the employees table.
And after clicking that, i could click on one employee and the department table would look the same (because its a employee from the same department) but the salary_by_job would only show the information regarding the job_id from that employee.
I'll try to show it from text in here:
Department (selected row = 1) = Department of Information (which has 3 employees)
Employees = X (with the job_id = admin), Y (with the job_id = manager) and Z (with the job_id = intern)
Salary_by_job = Admin, with data bla bla bla, Manager, with the data bla bla bla and Intern, with the data bla bla bla
And next i would click on the Employee X and the result would be:
Department (selected row = 1) = Department of Information (which has 3 employees)
Employees = X (with the job_id = admin)
Salary_by_job = Admin, with data bla bla bla
Can something like that be done? If so, how?
I'm thinking of doing that with bindings attached to each table and having the bindings go back and forth.
If someone has a idea of how to do this, please respond, it may be usefull.
Thanks so much for all the help. Have a wonderfull day!

FredericoSB,
Have you tried adding a setPropertyListener for the tables and change the collectionModel for the 3rd table accordingly?
Ex :  Assume you have three tables, Parent (VL)->Child (VL)->GrandChild. There is a relation between Parent (VL)->GrandChild.
Now, you can have tree bindings for both the GrandChilds (say GrandChildViaParent and GrandChildViaChild).
Your jspx could be something like
<af:table id="parent" value="#{bindings.Parent.collectionModel}"...... />
<af:table id="child" value="#{bindings.Child.collectionModel}"...../>
<af:table id="grandchild" value="#{bindings.GrandChild.collectionModel}" ..../>
If all your tables are read-only, then you could change this to something like
<af:table id="parent" value="#{bindings.Parent.collectionModel}"...... >
     <af:setPropertyListener from="Parent" to="#{viewScope.tableName}" type="selection"/>
</af:table>
<af:table id="child" value="#{bindings.Child.collectionModel}".....>
     <af:setPropertyListener from="Child" to="#{viewScope.tableName}" type="selection"/>
</af:table>
<af:table id="grandchild" partialTriggers="parent child" value="#{viewScope.tableName=='Parent'?bindings.GrandChildViaParent.collectionModel:bindings.GrandChildViaChild.collectionModel}" ..../>
This is just a sample. You could implement the same for all the properties in the grandchild table as EL to make it editable as well.
This is without coding. If you care to code a bit, you could use a Dynamic Table in place and bind the value accordingly in each of the table's selectionListener (which would be a neat approach)
