Hi,
I add a new entry to a DataTable and want to scroll it into the view, as it
is added at the end of the list.
@UiHandler("buttonAdd") {
onAdd(ClickEvent evt) {
Foo foo = new Foo();
dataProvider.getList().add(foo);
dataGrid.getRowElement(dataProvider.getList().indexOf(foo)).scrollIntoView();
}
But when I add the items I get following errors.
Adding 1st item:
com.google.gwt.event.shared.UmbrellaException: Exception caught: Row index:
0, Row size: 0
Adding 2nd item:
com.google.gwt.event.shared.UmbrellaException: Exception caught: Row index:
1, Row size: 1
WHY??
com.google.gwt.event.shared.UmbrellaException: Exception caught: Row index:
1, Row size: 1
