Default Refreshing ListField Items

Please Login to Remove!

Hello every one...



I have created a screen which uses a listfield to display the contents of a persistent vector object.

Now when I remove the element from that list.. It does fine to remove the element from persistent vector but from list it always removes the last element of the list... and when I go back (popping this screen) and again come to this screen the list shows up as it should be(with the selected element removed).



I Have tried all poss. ways like deleting and adding the list again.... etc... please suggest a way out...



Here's the relevant code.. of the ListScreen...



Please Help!!





final class ListScreen extends MainScreen {

ListField myListLS = new ListField();
ListCallback myCallbackLS = new ListCallback();


public ListScreen(ListField myListbl,ListCallback myCallbackbl) {
super();

LabelField title = new LabelField("List",
LabelField.ELLIPSIS | LabelField.USE_ALL_WIDTH);
setTitle(title);
myListLS=myListbl;
myCallbackLS = myCallbackbl;
myListLS.setCallback(myCallbackLS);
add(myListLS);
addMenuItem(addnum);
addMenuItem(remove);

}

public MenuItem addnum = new MenuItem("Add Number", 110, 10)
{
public void run()
{
UiApplication.getUiApplication().popScreen(UiAppli cation.getUiApplication().getActiveScreen());
UiApplication.getUiApplication().pushScreen(new AddScreen());
}
};
public MenuItem remove = new MenuItem("Remove", 110, 10)
{
public void run()
{
int i = myListLS.getSelectedIndex();
SmsHide._poData.removeElementAt(i);

synchronized (SmsHide.store)
{

SmsHide.store.setContents(SmsHide._poData);
SmsHide.store.commit();
}


Dialog.inform("Number Removed!! Press OK to Add a new number");
myListLS.delete(i);
}
};
