Hi again Tom,

I think the problem is that popupDataDialog ends up adding the selected data in 
a thread:
    Misc.run(new Runnable() {
            public void run() {
                try {
                    addNewData(clonedList);
                } catch (Exception exc) {
                    logException("Selecting new data", exc);
                }
            }
        });

I am refactoring this code so you can now directly call:
 List<DataChoice> choices = selectDataChoices(dialogMessage, from, multiples, 
categories);
Instead of calling popupDataDialog. This just returns the list of selected 
choices.


I'm checking this in right now.
