Apps NullPointerException, can't see why??

[motoko]

Hello guys, please have a look at this code and see if you could help me out. viewItem is populating from a database and the method fillRemindersData(long rowId) is only called from the reminder class. I don't know why i am getting a nullPointerException when calling the viewitems.fillRemindersData()method. if i comment the line, the code works fine and the rowId is correct. hat could be the reason? thanks

// this is a reminder class
public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.view_list);
		adapter = new DBAdapter(this);
		viewItems = new ViewItems();
		fillReminder();		
	}
	
	private void fillReminder() {
		Bundle extra = getIntent().getExtras();
		if(extra != null){
			rowId = extra.getLong(DBAdapter.KEY_ID);
			
			
			message = extra.getString(NewItem.Test);
		}
		Toast.makeText(this, message + "its ok here" + rowId, Toast.LENGTH_LONG).show();
		viewItems.fillRemindersData(rowId); // having a null pointer exception here.
}

And important part of the viewItems class is:

public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.view_list);
		adapter = new DBAdapter(this);
		adapter.open();
		fillData();
		list = (ListView)findViewById(android.R.id.list);
		list.setOnItemClickListener(this);
		
		
	}
	
	
	protected void fillData() {
		
	Cursor c = adapter.retrieveItems(); // method in sqlitedatabase
	startManagingCursor(c);
		
String[] from = new String[]{DBAdapter.NAME, DBAdapter.START_DATE, DBAdapter.START_TIME};
int[] to = new int[]{R.id.viewNameId, R.id.viewDateId, R.id.viewTimeId};
				
customCursorAdapter items = new customCursorAdapter(this, R.layout.view_items, c, from, to);
				setListAdapter(items);			
		       
	}
	
           protected void fillRemindersData(long Id) {
           long row = Id;
          Cursor c = adapter.retrieveRow(row); // method in sqlitedatabase
           startManagingCursor(c);
		
String[] from = new String[]{DBAdapter.NAME, DBAdapter.START_DATE, DBAdapter.START_TIME};

int[] to = new int[]{R.id.RemindNameId, R.id.remindDateId, R.id.remindTimeId};
				
customCursorAdapter items = new customCursorAdapter(this, R.layout.remind_viewer, c, from, to);
setListAdapter(items);			
		       
	}

Have you tried moving the } bracket on your if to after the point where you populate your list

Your code

[COLOR="DarkRed"]}[/COLOR]
Toast.makeText(this, message + "its ok here" + rowId, Toast.LENGTH_LONG).show();
viewItems.fillRemindersData(rowId); // having a null pointer exception here.

Alternative

Toast.makeText(this, message + "its ok here" + rowId, Toast.LENGTH_LONG).show();
viewItems.fillRemindersData(rowId); // having a null pointer exception here.
[COLOR="DarkRed"]}[/COLOR]

I think if your Bundle is empty you will get a null pointer exception.
