                          </af:selectBooleanCheckbox>
                        </af:column>
facing two issue
1: When this popup appears and in table I have say 5 rows. If i check any of the rows checkbox other then first row it shows checked but again shows that checkbox unchecked. But if I check again any row that remain checked.
2. Now if i click to sort this checkbox column all checkbox become unchecked.
So please suggest wht may be the cause. I am using Studio Edition Version 11.1.2.4.0
Also I want to know how we can apply caseInsensitive sorting on table.
Thanks

Answer 1

The framework implements table sorting by re-executing VO's query with added ORDER BY clause (i.e. the sorting is not performed in-memory but through re-execution of the query). I suppose that the SelectUser attribute is a transient one. When the query is re-executed you lose the values of the transient attributes. This behavior is by design, it is not a bug.
