createEditableCopyOfDatabaseIfNeeded create an empty copy of db!!!

Question

Hi! I'm using the "famous" :) function createEditableCopyOfDatabaseIfNeeded for create an editable copy of my db in an iphone app.. The function copy the original db in the documents directory only if there isn't already a copy of the db.. pretty simple.. but now I'm in trouble because I don't know why but with SDK 3.2.3 in iOS 4.1 the function copy my db.... EMPTY!!!

Here is the code:

- (void)createEditableCopyOfDatabaseIfNeeded  
{ 
    // First, test for existence. 
    BOOL success; 
    NSFileManager *fileManager = [NSFileManager defaultManager]; 
    NSError *error; 
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
    NSString *documentsDirectory = [paths objectAtIndex:0]; 
    NSString *writableDBPath = [documentsDirectory stringByAppendingPathComponent:@"funghi.sql"]; 
    success = [fileManager fileExistsAtPath:writableDBPath]; 
    if (success) return; 
    // The writable database does not exist, so copy the default to the appropriate location. 
    NSString *defaultDBPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"funghi.sql"]; 
    success = [fileManager copyItemAtPath:defaultDBPath toPath:writableDBPath error:&error]; 
    if (!success) { 
        NSAssert1(0, @"Failed to create writable database file with message '%@'.", [error localizedDescription]); 
    }
}

The db is full and correct! I can read the original db with the sqlite plugin of firefox! Any help?

Thx a lot!!!
