Question

i have an awkward problem where calling to [self invalidateModel]; does not redraw my custom cells.

I have a TTTableViewController with an action sheet that allows to order the display of a table when pressed. The data gets redrawn correctly but the cells are not redrawn. Instead there are reused.

To illustrate better :
In my - (void)layoutSubviews { of my CustomTableItemCell class i have this :

if (bookmarked) {
        UIImage *bookmark = [UIImage imageNamed: @"[e-mail]"];
        TTImageView *bookmarkView = [[TTImageView alloc] init];
        bookmarkView.defaultImage = bookmark;
        bookmarkView.frame = CGRectMake(297, 0, 16, 27);
        [self.contentView addSubview:bookmarkView];
        TT_RELEASE_SAFELY(bookmarkView);
}

Basically if I get a bookmarked item, I want to display a ribbon on the right of my cell. This ribbon gets display correctly.
When I reorder my cell with the action sheet method and call invalidateModel, the first cell which didn’t have any ribon gets putten at a place where was previously a ribbonned item but without redrawing the cell, thus giving a ribon to an item without ribbon.

Code source :
This is my createDatasource function of my TTTableViewController :

- (void)createModel {
    self.dataSource = [ServiceRequestDetailedDataSource viewDataSource:self.typeOfAction andOrderBy:orderBy];
    // If dataSource nil, show an empty Message
    if (self.dataSource == nil) {
        [self showEmpty:YES];
    }
}

This is my action sheet action of my TTTableViewController that change the orderBy and calls invalidate model :

-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
    if (buttonIndex == 0) {
        self.orderBy = @"portfolio";
    [self invalidateModel];
}

Any tips would be great, I am really stuck here :'(

Found it, just use reuseidentifier. My bad.
