Please try this

ObjectListField olf = ObjectListField() ;
olf.set(new String[]{"1", "2"});

Thankyou for the reply.
nope its not working. the error is after calling list.setCallback();,the class implementing the interface ListFieldCallback interface is initialised,then the method :
public void drawListRow(ListField list, Graphics g, int index, int y, int w)
{
String text = (String)listElement.elementAt(index);
g.drawText(text, 0, y, 0, w);
} is being called.
listElement is a java.util.Vector.
here listElement.elementAt(index) is giving ArrayIndexOutOfBoundsException
in the tutorial also the code is exactly like this.
