Row selection messed up after sorting

Question

JDev version: 11.1.1.4 (but also reproducable in 11.1.2.1)
See http://kpdwiki.be/Bart_L/tableIteratorSortSync.zip (open BO726.jws and run runThis.jspx)
Situation:
- iterator 'EmployeesIterator' which points to a view with Employees -> ChangeEventPolicy='none'
- Bindings which all point to this iterator:
- Tree binding 'Employees' used for an af:table with employees (firstname, lastname)
- Attribute bindings 'FirstName' and 'LastName' which is used in a formLayout to show the currently selected employee
- Operation Bindings to iterate through the employees (First, Previous, Next, Last)
- runThis.jspx
- formlayout with FirstName and LastName
-> partialtriggers: Next-button and table (for the rest, no partialtriggers)
- Next-button
- table with employees
Problem:
1) if you select one of the employees in the table, and sort one of the columns, the first row will be selected. This is normal behaviour
2)
a) select the first row
b) press the 'Next' button a few times. Now the selected employee in the iterator is 'X'
c) in the table, select employee 'X' by clicking on its row
d) sort one of the columns.
Result: In the iterator, the first row of the table is selected, while the table selection shows something different!
--> this is different behavior than the situation described in 1)
--> after doing something with the table (sorting, filtering, selecting rows, ...), I would expect that the selected row in the table is always the same as the selected row in the iterator.
Questions:
1) Is this a bug?
2) If yes, is this a known bug?
3) If no: am I doing something which is not allowed? Or should I do something different here?

Answer 1

I can reproduce the problem in 11.1.1.4.
First employee is Steven King, which is selected. I then press next a few times till the output text reads Bruce Ernst (the table selection is still on Steven King, while the iterator points to Bruce Ernst). I then click on Bruce Ernst in the table, so it is selected (iterator stays on the same record). If I then sort the table, the table selection stays on Bruce Ernst, while the output text shows the first record in the table after the sort.
We have the same issue using a non-modal popup to edit table rows (non-isolated task flow, sharing data controls & transaction). Our edit popup has navigation controls. When we scroll through records in the popup, the table selection doesnt refresh (changeEventPolicy = none). If we then select the record in the table that we scrolled to in the popup , without closing the popup, and then sort the table (with the popup still open), the selection stays on the previously selected record, whille the popup shows the first record in the table after the sort.
