Hi,
I use CellTable to display the data stored in db. Data are provided
using AsyncDataProvider. The last row that is displayed is an empty
row used to add the new entry to db. After adding the entry I download
the data from visible range again to refresh the view.
Here's how it's done:
public void redraw() {
mt.redraw(); //an instance of CellTable
madp.getMovies(mt.getVisibleRange().getStart(), mt.getPageSize()); //
an instance of AsyncDataProvider
}
The getMovies() method:
public void getMovies(final int offset, final int limit) {
AdminAsyncCallback<MovieResultDTO> cb = new
AdminAsyncCallback<MovieResultDTO>() {
@Override
public void onSuccess(MovieResultDTO result) {
if (result != null && result.getMovies() != null && !
result.getMovies().isEmpty()) {
updateRowCount(result.getSize(), true);
updateRowData(offset, result.getMovies());
} else {
updateRowCount(0, true);
}
}
};
AdminService.Async.service().getMovieResultDTO(offset, limit, cb);
}
There's one problem. The last row isn't refreshed and it holds the
entered data. This row is added to the list downloaded from db every
time the data are refresed. And it has null values cause I see it in
logs. How can I clean the cell table before it's repopulated?
