Hi Jeff,
The demo uses a trick to make the List size bigger than what it really
is. This breaks the List contract though so not all List methods work
as expected. Sorting is one of them.
The real issue is that Table should not attempt to sort the list
because it does not have access to all the rows.
Since you are lazily loading the rows for the specified page you are
also responsible to ensure the data is sorted, most probably using an
SQL ORDER BY clause.
To get around the fact that Table tries to sort the rows you can do this:
public void onInit() {
Table table = new Table() {
// Override sortRowList to do nothing
protected void sortRowList() {
}
}
}
Will this work for you?
We should probably look at ways to make this setup easier in a future release.
kind regards
bob
