UITableViewCell going black when selected programmatically - uitableview

Question

I was wondering why this code would give me black UITableViewCells when I set the selected property ON. If I do that, the content of the cell turns completely black, and I have no idea why.
Here's the code

#import "TableViewAdapter.h"

#implementation TableViewAdapter
#synthesize model;
- (id) initWithModel: (Model*) model {
self = [super init];
if(self != nil){
self->model = [model retain];
}
return self;
}
- (void) dealloc {
[model release];
[super dealloc];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return [[model cellData] count];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [[[model cellData] objectAtIndex: section] count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = nil;
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
cell.textLabel.text = [[[model cellData] objectAtIndex: indexPath.section] objectAtIndex: indexPath.row];
if(indexPath.row == [[model currentSelected] row] && indexPath.section == [[model currentSelected] section]){
cell.selected = YES;
} else {
cell.selected = NO;
}
return cell;
}
#end

If you need more code, shout. :)
Many thanks in advance,

I was having the same problem and fixed it by moving the cell.selected = YES into tableView:willDisplayCell:forRowAtIndexPath instead.
I think it might be related to the note at the bottom of the UITableViewCell docs about changes to background color requiring use of tableView:willDisplayCell:forRowAtIndexPath (presumably selected sets the background color).
