I'm imlpements a AbstractListModel,

public class HugeDataListModel extends AbstractListModel {

private final int pageSize;
private final PageDataModel innerModel;

public HugeDataListModel(int pageSize, PageDataModel dataModel) {
    this.pageSize = pageSize;
    if (pageSize <= 0) {
        throw new IllegalArgumentException("page size should be positive > integer");
    }
    innerModel = dataModel;
}

public Object getElementAt(int index) {
    int residual = index % pageSize;
    return innerModel.toPage(index / pageSize).get(residual);
}

public int getSize() {
    return innerModel.getTotalSize();
}

}

I have a table with 50,000 records, but i dont know why the method getSize() is call around 150,000 times

The oder code:

HugeDataListModel hdlm = new HugeDataListModel(10, new ProcesoPageDataModel(10)); lb.setModel(hdlm); lb.setItemRenderer(new ProcesoRender());

Thanks
