Hi All !
I am facing a problem, in displaying the data on the screen ..
I have Tried this code ..
SearchFrame.java
public class SearchFrame implements
Frame {
public static final SearchFrame instance = new SearchFrame();
DataList myList = new DataList();
ResultDataProvider resultDetail = new ResultDataProvider();
Screen screen ;
String [][] str= {{"Hi", "Welcome To the World of Kuix !"},{"Hello !","How greatly U R enjoying It ? " }};
public void onAdded() {
screen = Kuix.loadScreen("/xml/mySearch.xml", myList );
screen.setCurrent();
}
public boolean onMessage(Object arguments, Object[] arg1)
{
if("show".equals(arguments))
{
Widget focusedWidget = screen.getFocusManager().getFocusedWidget();
if (focusedWidget instanceof ListItem)
{
DataProvider dataprovider = ((ListItem) focusedWidget).getDataProvider();
if(dataprovider !=null )
{
ResultDataProvider result = (ResultDataProvider) dataprovider;
SearchItem.instance.setResult(result);
System.out.println(result);
//searchDetail();
Kuix.getFrameHandler().pushFrame(SearchItem.instance);
}
}
return false;
}
if("search".equals(arguments))
{
for (int i=0; i<str.length ; i++)
{
myList.addItem(DataList.LIST_PROPERTRY, new ResultDataProvider(str[i][0],str [i] [1]));
}
}
return false;
}
public void
onRemoved() {
myList= null;
resultDetail = null;
screen = null;

this.result = result;
System.out.println("<-----In Frame Search Item--------->" );
System.out.println(result.getStringValue("resultLabel"));
);
}
public void onAdded()
{ System.out.println("On Added Method" );
System.out.println(result.getStringValue("resultDetail" ));
screen= Kuix.loadScreen("/xml/searchDetail.xml", result);
screen .setCurrent(); }

Kuix.getFrameHandler().removeFrame(instance);

Hello!
Problem Occurs, when I press the Search Button multiple times .. then it just append the same value on the screen henceforth .. in my opinion, It might be, the screen is not being cleared .. on the button event ..
