ADF selectOneChoice filtering - Oracle ADF mystics

Question

Hi clever guys,
I wanna filter a selectOneChoice component based on the value of another component using JUCtrlListBinding.filterList(..) in the managed bean (onValueChange)
based on Frank Nimphius' article
[http://www.oracle.com/technetwork/developer-tools/adf/learnmore/90-filter-adf-bound-lists-508190.pdf]
Say my selectOneChoice contains 10 rows with different pointId attribute - POINTA, POINTB, POINTC.
If we filter on pointID, which is contained only in 1 row, then the filter returns all the rows - filtering is not applied. As soon as a specific pointID is contained at least in 2 rows, the filtering works and only these rows are returned.
Say we display selectOneChoice with attributes productId and pointId. Rows, before filtering, are like this
- PRODUCT1, POINTB,
- PRODUCT2, POINTA,
- PRODUCT3, POINTB,
- PRODUCT4, POINTC,
- PRODUCT5, POINTC,
- PRODUCT6, POINTB,
- PRODUCT7, POINTC,
If we tell JUCtrlListBinding.filterList() to select only rows with POINTB or POINTC, it works fine (returns 2 resp. 3 rows), because they are contained in 2 or 3 rows. If I filter on POINTA, all rows (7) are returned (filtering is not applied). As soon as I insert 1 more row for POINTA, it works.
My code snippet>
JUCtrlListBinding listBinding = (JUCtrlListBinding) bindings.get("productId1");
listBinding.getDCIteratorBinding().getViewCriteria().clear();
HashMap m = new HashMap();
m.put("pointId", selectedPointId);
listBinding.filterList(m);
I write out the contents of listBinding values with System.out... just before and just after the filterList method, that's how I can see that this method behaves like that.
Guys, do you have any idea on what could go wrong and how to workaround it?
Thanks a lot.

Thanks for the quick response!
Using the department / employee example... I'm trying to create a form that allows a user to create a new department. I have dragged the "Department" object (located under queryDepartmentFindAll()) over to my jspx form. A form with corresponding fields is created.
I notice that no field was created for employeeId. I expand the "Department" object (again, under queryDepartmentFindAll()) and observe that "Employee" is present, as a list (expanding Employee provides access to employee object attributes along with another list entitled departmentList).
I know that it's unlikely that only one employee would be selected in the creation of a department... but I'm sticking to the example...
So, I drag the "Employee" (again, under queryDepartmentFindAll()) object over to the newly created form and from the pop-up menu I choose selectOneChoice as the desired component. I run the jspx page, Internet Explorer 7 browser pops up and all labels display on the page, all fields but no selectOneChoice component appears on the screen... the space is there for it but it appears to be invisible. I have checked the Employee table and there is data to be displayed... it's just that I must be missing something...
