Accessing the rowItem from the populateItem of a column
Hi all,
I need to do an ajax refresh of a whole line of a table.
On the left of the table there is a dropdown and when the selection is
changed the other fields of the table should be refreshed accordingly.
So I have a column where the dropdown is defined and here I add an
"onchange" behaviour where I should add the entire row to the ajax
target.
But in the populateItem of ICellPopulator I have no access to the rowItem.
With this hack
Object repeatingView =
ReflectionUtil.getPrivateField(cellItem, "parent");
return (Item) ReflectionUtil.getPrivateField(repeatingView, "parent");
I can reach the rowItem and everything works perfectly.
Now I was looking for a cleaner way to do this.
The item I need is the one that is received from the
populateItem(Item) of AbstractDataGridView so I could override this
call super and add the tracking of the current rowItem making it
available, as a field, in subsequent ICellPopulator.populateItem
calls. Not very nice anyway.
Do you have any suggestion? Could a getParent method added to cellItem
to access to the rowItem it belongs to?
Thanks, bye
Lorenzo

That should work fine in 1.3.3.
I thought this was what you were looking for:
public class SomeColumnClass extends AbstractColumn {
public void populateItem( Item cellItem, String componentId, IModel
rowModel ) {
MarkupContainer rowItem = cellItem.getParent().getParent();
rowItem.add( new SomeBehaviour() );
}
}
?

Hi, thanks for the replies.
I'm using wicket 1.3.3 and this method was not yet present. I'm not
upgrading due to some problems with ajax tests and WicketTester.
Anyway I cannot see many other options, other than using a ListView
instead of a table or the one described above.
Bye
Lorenzo

cellItem.getParent().getParent() will get the row component, but it's
not a very clean solution.

Hello,
Can't you just make the parent's field final and use : Parent.this.cellItem
?
HTH,
Pierre

Du calice du royaume total des âmes
Ecume jusqu'à lui l'infinité.
