Re: Getting the currently selected item in a ListBox
It's a timing issue - having used a MouseUpHandler, you're assuming the
list box will already have handled the MouseUp event before you get
called (which it looks like it doesn't).
Use a ChangeHandler instead - this will be called after the ListBox has
handled the change.
Also, if you were to use a MouseUpHandler, then you wouldn't get events
relating to the listbox changing through the keyboard. ChangeHandler
gets changes regardless of how they occur.

Getting the currently selected item in a ListBox
This seems like a silly question but it does not work for me.
When I use .getSelectedIndex() on a ListBox it returns the previously
selected item in history, not the one I selected just now.
What is going on?
cmbDefinitionSelection.addMouseUpHandler(new MouseUpHandler() {
public void onMouseUp(MouseUpEvent event) {
int index =
cmbDefinitionSelection.getSelectedIndex();
txtDefinition.setText(cmbDefinitionSelection.getItemText(index));
}
});
