jcombobox - arrayindexoutofbounds exception

[Sue]

I have the following code,
and always get the error exception
java.lang.ArrayIndexOutOfBoundsException

try{
jComboBox1.removeAllItems();
}
catch (Exception ex){
System.out.println("exception " + ex);
}

The value for selectedIndex for this combo box seems to default to -1
even though I change it to zero -- could this be the problem?

Thank you very much.

1) Are you sure your jComboBox1 contains any objects?
The selectedIndex == -1 indicates that nothing is selected; if the
combobox is empty you can't change the index to zero by selecting an object.

2) Are you sure the exception is raised by calling removeAllItems()?
It shouldn't do this, so I suspect you left out some essential code in
the above quote...

Paul.

-1 means no selection, 0 means the first item is selected. You should
not select item 0 after removing all items.
