Hi,

When displaying double values in textfields I use:

double tmp = Double.parseDouble(stringWithDouble.getText());
sizeTextField.setText(String.valueOf(df0.format(tmp))); 
//df0.applyPattern("###,###") i.e. 0 decimals

If the stringWithDouble is formatted to ex. 1,234 I get:

java.lang.NumberFormatException: For input string: "134,099"
  at 
java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)

  at 
java.lang.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:1207)
  at java.lang.Double.parseDouble(Double.java:220)

I think there is a way to use formatting when parsing strings but I 
can't find it.

Magnus

double tmp = df0.parse(stringWithDouble.getText()).doubleValue();
