Hi alex,
sorry but I can't see how fix the number of rows as I'm using a
memoryProxy object.
So, the timer is defined as follows:
Timer t = new Timer() {
public void run() {
getShipInfo();
}
};
where getShipInfo() is
private void getShipInfo() {
MainEntryPoint.getServiceWsNaviInMare().getInfoNaviInMare(new
AsyncCallback() {
public void onFailure(Throwable caught) {
throw new UnsupportedOperationException("Not supported
yet.");
}
public void onSuccess(Object result) {
Vector listaNavi = (Vector) result;
GWT.log("Lista Navi Ricevuta: "+listaNavi.toString(),
null);
if (listaNavi.size()>0) {
Object[][] data = new Object[listaNavi.size()]
[15];
Iterator i = listaNavi.iterator();
int index = 0;
while (i.hasNext()) {
Nave unaNave = (Nave) i.next();
data[index] = new Object[]{
unaNave.getIdNave(), unaNave.getNomeNave
(),
unaNave.getLocalita(), unaNave.getImbarco
(),
etc....
GWT.log("Nave "+data[index][0]+data[index]
[1].toString(), null);
index++;
unaNave = null;
}
if (store!=null) {
store.removeAll();
}
MemoryProxy proxy = new MemoryProxy(data);
ArrayReader reader = new ArrayReader(recordDef);
store = new Store(proxy, reader);
store.load();
store.commitChanges();
grid.reconfigure(store, columnModel);
//240209Miki: x diminuire memory leak ...
grid.clear();
data = null;
proxy = null;
reader =null;
store = null;
}
}
});
}
I've tried with FF and there's no problem...so it's an issue with ie7.
Can you see some big error in the code i posted just above? thx for
help!
