Hello,

I am having trouble with the getSelectedIndex() method of ObjectListField.
Supposedly, when there is no selected index, it returns -1. But how come it always returns the index of the last item?

To demonstrate, i created my own dialog that has a similar functionality to the "Select Device Dialog" of the Bluetooth application in BB. I have an ObjectListField and a Cancel Button. What i simply did is change the label of the button to show the selected index. I have attached my sample code below.

public class MyDialog extends Dialog
{       
        private ObjectListField m_list;
        private ButtonField m_btn;      

        public MyDialog ()
        {
                super("Select Device:",null,null,0,Bitmap.getBitmapResource("bluetoothIcon.PNG"),Manager.FOCUSABLE);

                m_list = new ObjectListField();
                m_btn = new ButtonField("Cancel",Field.FIELD_HCENTER);
                m_list.set(new String[]{"first","second"});

                add(m_list);
                add(m_btn);
        }

    protected boolean navigationClick(int status, int time)
    {   
        m_btn.setLabel(Integer.toString(m_list.getSelectedIndex()));

        return true;
    }
}

Can somebody help me on this problem? Is there something wrong with my code or is the API buggy? All i want to happen is to return a -1 index if there is no item selected in the list.

Also, I have tried the isFocus() method using it to check if the list is being focused, it always returns false eventhough the list is OBVIOUSLY being focused. I have run out of options on how to determine the solution to this problem. please help!

Thanks a lot.

This may seem like a stupid question - Is it possible that you're checking the values in the list to see what is there and accidentally selecting an item?

Are you by any chance scrolling down past the bottom of the list to select & click the button?
Or are you invoking getSelectedIndex when the screen is no longer on top?
I use getSelectedIndex in several apps and confirm that it works perfectly on every simulator & device that I've tested on (from 4.2 up).

Hi jacytan,

Did you ever get this resolved? I'm running into the same problem with some code I'm working on now.

Thanks,

Hi squished18,

Here is what i did.

    
protected boolean navigationClick(int status, int time)
{   
     if(this.getLeafFieldWithFocus() == m_list)
     {
        m_btn.setLabel(Integer.toString(m_list.getSelectedIndex()));

        return true;
     }
     return false;
}

Do you get it?
