Dialog Box in Activity group inside a TabActivity not working

Question

I'm trying to run an ActivityGroup embedded inside another ActivityGroup. (Example : an ActivityGroup inside a TabActivity)

This seems to display properly but throw an exception when I'm trying to display a modal box like an AlertDialog.

TabActivity

• Tab1
• Tab2
• MyGroupActivity
• • ChildActivity1
• • ChildActivity2

If childActivity1 or 2 try to display a DialogBox I'm getting this exception :

ERROR/AndroidRuntime(2449): 
android.view.WindowManager$BadTokenException: Unable to add window -- 
token android.app.LocalActivityManager$LocalActivityRecord@43424620 is 
not valid; is your activity running? 

If Anybody know please reply...

This is my dialog box code

           final Dialog dialog = new Dialog(EditDeleteReqCardList.this);
  dialog.setContentView(R.layout.customdialougbox);
        dialog.setTitle("Request Card - "+reqid);

        // set the custom dialog components - text, image and button
        TextView text = (TextView) dialog.findViewById(R.id.text);
        text.setText("Do You Want to Delete This request Card ?");
        ImageView image = (ImageView) dialog.findViewById(R.id.image);
        image.setImageResource(R.drawable.dialougimage);

    Button dialogButton = (Button)    dialog.findViewById(R.id.dialogButtonOK);
        Button cancelbutton = (Button) dialog.findViewById(R.id.cancel);
        dialogButton.setText("Yes");
                   dialog.show();

use final Dialog dialog = new Dialog(getParent());
