title: Text Input error / validation and restore previous correct value in Flex
body: <p>I have text input boxes. There is validation for each of the boxes using numberValidator.
  Now, the thing is that am using alert box to show if any error occurs.</p>
  
  <p>Flowchart ::</p>
  
  <p>1> Insert value in textBox.
  2> NumberValidator validates the input on "trigger=change".
  3> If error, alert message is displayed. The user clicks OK to go back to form.
  4> Focus set back to the TextBox.
  5> But, alert box makes the text input value blank / null. i.e. Both the previous error value entered by user and the default correct value will not be displayed now.</p>
  
  <p>Goal : Display the most recent correct value that was entered in the text box. Not the default of any other, but the most recent correct value entered by the user.</p>
  
  <p>can anyone help ??</p>
