[Wicket-user] Why item.getIndex() always zero?
..
int c = 0;
..
List columns = new ArrayList();
columns.add(new AbstractColumn(new Model(操作)){
public void populateItem(Item cellItem, String
componentId, IModel
model){
c += cellItem.getIndex()+ 1;
System.out.println(cellItem.getIndex():+cellItem.getIndex());
System.out.println(c:+c);
cellItem.add(new ActionPanel(componentId,
model));
}
});
..
add(new DefaultDataTable(table, columns, new ColumnDataProvider(),50));
..
the Class ColumnDataProvider extends SortableDataProvider.
cellItem.getIndex() always return 0.why?

Re: [Wicket-user] Why item.getIndex() always zero?
Because the cellItems are the column items...
You only have one column, so it will always return 0 (first column).

//System.out.println(cellItem.getIndex():+cellItem.getIndex());

});
columns.add(new PropertyColumn(new Model(type),

columns.add(new PropertyColumn(new Model(control),
activeDate));
...
I could misUnderstand your means but there are many columns and many
ActionPanel.
