LOV with a query Bind Parameter

Question

Hello,
I am following the JHeadStart PDF tutorial over the HR Schema. On the page 45 this tutorial shows how to make a Dynamic Lookup with a Query Bind Parameter to choose the employees of a department with the expresion "p_dpt_id=#{bindings.DepartmentsDepartmentId.inputValue}".
After that I tried to make the same using a LOV instead of a Lookup but on the popup window opened with the LOV table the "#{bindings.DepartmentsDepartmentId.inputValue}" value is null and I can´t access to this information. If on the LOV definition I write for example "p_dpt_id=30" this work ok and filters the query for the employees of the departen 30, but not with "p_dpt_id=#{bindings.DepartmentsDepartmentId.inputValue}"
There is another way to do that?
Thank you very much

I have done this task using the aid of the JHeadstart manual and these two previously posted threads,
Group Used as LOV does not return records
Query Bind Parameters and LOV's [JHS 10.1.3.1]
The actual process to do it feels rather unintuitive and complicated, but I've tested it and thus far is works flawlessly.
I whipped up a demo of this using the HR schema and JHeadstart, maybe I will post it on here.
