How could I avoid the SAVE dialog in my regular Blackberry application?

Question

I write a Blackberry app and click on the screens one by one (three times in a row)

Screen 1 displays Screen2 and Screen2 displays Screen3

When I press the "Back Key" on my Blackberry ie device, in bold 9700, its request calls up a dialog box with a picture of a question mark and the Save button. Cancel Cancel.

Why does this dialog box appear? How can I avoid this dialogue?

Please help thanks to SIA

Answer 1

You can avoid this type of dialog by overriding the onClose method for this screen:

public boolean onClose() 
{

  this.close();
  return true;
}

Answer 2

:

• isDirty() (: Blackberry - BasicEditField?):

  public boolean isDirty() { return false; }

• onSavePrompt() ( Blackberry - BasicEditField?):

  protected boolean onSavePrompt() { return true; }

Answer 3

Just write this code in the specified class:

 protected boolean onSavePrompt() 
   {
       return true;
   }  

The Save Hint dialog box appears.
