Overview

In Series 40, the value of TextField.NUMERIC must not exceed the value of 2147483646 (Integer.MAX_VALUE-1), otherwise an IllegalArgumentException is thrown.

Description

The integer value inserted in TextField defined with the TextField.NUMERIC constraint must not exceed the value of 2147483646 (i.e. Integer.MAX_VALUE-1) in Series 40, otherwise an IllegalArgumentException is thrown. In S60, this value may be exceeded without the exception.

How to reproduce

Use, for example, the following piece of code to reproduce this issue:

  TextField textField = new TextField("Enter Number:", "", 10, TextField.NUMERIC);
  long n = Integer.MAX_VALUE;
  textField.setString(Long.toString(n));
  System.out.println("OK for Integer.MAX_VALUE, i.e. " + n);
  try {
      textField.setString(Long.toString(++n));
  }
  catch (IllegalArgumentException e) {
      System.out.println("FAILED for Integer.MAX_VALUE + 1, i.e. " + n);
  }

Solution

Avoid using values starting from Integer.MAX_VALUE and higher with the TextField.NUMERIC constraint in Series 40.
