[news.eclipse.technology.nebula] StringIndexOutOfBoundsException when ed

["Nelson Fernando" <java14@xxxxxxxxxxx>]

Hi im having some trouble using FormattedText for formatting number fields 
in a Eclipse RCP  application .


The code involving the text fields looks like this :


     FormattedText formatterText = new FormattedText(textField); ;
            Locale.setDefault(Locale.US);
     formatterTextField.setFormatter(new 
NumberFormatter("-##########0.00"));

When I look into the text fields (executing the aplication) they work fine 
but if I input a number ( ex: 125.23 ) select it using the mouse or SHIFT 
key  and press a number key replacing it or deleting the contents of the 
field using backspace I get a  out of bounds exception comming from 
TextObservableValue , heres a stacktrace :
