Core Data crash on a seemingly normal NSString field

I have another strange bug which I cannot figure out.

I try to create a tableviewcell with the code below:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    TableViewCellController *cell = (TableViewCellController *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        [[NSBundle mainBundle] loadNibNamed:@"TableViewCell" owner:self options:nil];
        cell = [_cell autorelease];
        _cell = nil;
    } 

    // Configure the cell... 

 int storyIndex = [indexPath indexAtPosition: [indexPath length] - 1];
 Article *article = (Article *)[articles objectAtIndex: storyIndex];
 cell.titleLabel.text = article.title;
 cell.siteLabel.text = article.site.name;

 cell.summaryLabel.text = article.description;

 [article release];

    return cell;
}

The problem is that I can populate the labels with any value, except with the description value. As soon as I do that I get a the following crash:

2010-12-22 16:07:13.165 iDoms[24086:207] CoreData: annotation: fault fulfilled from datab开发者_运维问答ase for : 0x8b16dd0 Program received signal: “EXC_BAD_ACCESS”. warning: Unable to restore previously selected frame. Data Formatters temporarily unavailable, will re-try after a 'continue'. (Not safe to call dlopen at this time.)

with 62820 line items on the stack. I have no idea where to start figuring this out. I am used to Java, and Objective-C has been a real nightmare so-far regarding little strange bugs.

The Article class looks like this:

//  Article.h

#import <CoreData/CoreData.h>

@class Site;

@interface Article :  NSManagedObject  
{

}

@property (nonatomic, retain) NSNumber * id;
@property (nonatomic, retain) NSString * title;
@property (nonatomic, retain) NSNumber * read;
@property (nonatomic, retain) NSString * link;
@property (nonatomic, retain) NSDate * pubDate;
@property (nonatomic, retain) NSString * description;
@property (nonatomic, retain) NSDate * lastUpdate;
@property (nonatomic, retain) Site * site;


@end

and

//  Article.m

#import "Article.h"

@implementation Article 

@dynamic id;
@dynamic title;
@dynamic read;
@dynamic link;
@dynamic pubDate;
@dynamic description;
@dynamic lastUpdate;
@dynamic site;

@end

The database contains data, and the particular field just the string "Test1". Any help is really appreciated as always!

The size of the stack trace leads me to believe that you've got an infinite recursion loop going somewhere.

I would look at the construction of the custom UITableViewCell that is getting created, namely the summaryLabel control and how it is wired into the cell.

I would also make sure that the articles array is property retained.

I do not know if this is related to your current issue, but you do not want to do the [article release]; in your cellForRowAtIndexPath method, as objectAtIndex does not give you a reference that needs to be released.
