I've added the line to push timestamp on the adapter but I still get only the value for presentation. Here's the code part:

Map<String,String> data = new HashMap<String,String>();
try {Reader r = new BufferedReader(new FileReader("C:\\primjer.txt"));
StreamTokenizer stok = new StreamTokenizer(r);
stok.parseNumbers();
// double sum = 0;
stok.nextToken();
while (stok.ttype != StreamTokenizer.TT_EOF) {
if (stok.ttype == StreamTokenizer.TT_NUMBER)
i++;
if(i%3==2){
data.put("timestamp", (new Date()).toString());
data.put("Next", Double.toString(stok.nval));
listener.update(item, data, false);
try {
Thread.sleep(10);
} catch (InterruptedException e) {
}
stok.nextToken();
}
stok.nextToken();
That part of code is in while loop. Now... The problem is that timestamp seems not to be sent. I get only Next. And if I changed that what do I have to add to client so that even timestamp gets shown in table? (Do I need schema or group?)
