setSelectedIndex in selectionListener (Tabs)

[Maaike]

I tried to swipe between tabs and add tabs 'on the fly', like mentioned here: Swipe to replace container.

When swiping to the previous tab, I add a new tab with 'insertTab' with index 0. Then I change the current tab with 'setSelectedIndex' (because current index is now 1). This is going ok when doing this for the first time (so when first showing the Tabs, I show the current one with current date, make a new one on index 0, change the index to 1 and I can swipe 'back' to the newly added tab with index 0).

I'm trying to add new tabs in the SelectionListener: when I'm on tab with index 0, I add a new one on index 0. The problem is: setSelectedIndex is not going well here. I'm always staying on the newly added tab at index 0, but I want to go to the 'current' tab, with new index 1. I hope you understand what I mean. 

Here is my code:

    public class SelectTabListener implements SelectionListener
    {


        public void selectionChanged(int oldSelected, int newSelected)
        {
            DateContainer dc = (DateContainer)swipeContainer.getTabComponentAt(newSelected);
            Date currentDate = dc.getDate();
           
            dateLabel.setText(dateFunctions.getDateString(currentDate));
           
            if (newSelected == 0)
            {
                Calendar c = Calendar.getInstance();
                c.setTime(currentDate);
                c.add(Calendar.DAY_OF_MONTH, -1);
                Date newDate = c.getTime();
                DateContainer newContainer = getDayListContainer(newDate);
                swipeContainer.insertTab("", null, newContainer, 0);
                swipeContainer.removeSelectionListener(selectTabListener);
                swipeContainer.setSelectedIndex(newSelected + 1);
                mainContainer.revalidate();


                swipeContainer.revalidate();


                swipeContainer.addSelectionListener(selectTabListener);
            }
        }

    }

I'm sorry I didn't search better. I already found the (working!) answer:

Extend the tabs of codename on so to set a limit

Just wrap the code in the body with 

Display.getInstance().callSerially(new Runnable() {
   public void run() {
        ... your code here
   }
});


Normally this is used to send data back to the EDT but in this case it can be useful to deffer a call to the next EDT cycle and let this event chain complete.
