List_SortColumn

  
The columns on my list all have List_SortColumn widgets, and filter input widgets, which are mostly textbox input fields; the List_SortColumn and textbox all go to the same "refreshtable" screen activity. On one of these filter texboxes I have an Input_Calendar widget. The problem is that as soon as the calendar pops up, the List_SortColumn gets triggered, and the calendar selection never gets recognized. Filtering works fine without the sorting widget. How can I have both?
I decided to implement my own version of List_SortColumn, and can now have both functions.
