Hi, so I have a class that I decleare as a singleton and in that class I have a NSMutableArray that contains some NSDictionaries with some key/value pairs in them. The trouble is it doesn't work and I dont't know why... I mean it crashes with EXC_BAD_ACCESS but i don't know where. I followed the code and it did create a new array on first add, made it to the end of the funtion ..and crashed ...

    @interface dataBase : NSObject {
    NSMutableArray *inregistrari;

}

@property (nonatomic,retain) NSMutableArray *inregistrari;



-(void)adaugaInregistrareCuData:(NSDate *)data siValoare:(NSNumber *)suma caVenit:(BOOL)venit cuDetaliu:(NSString *)detaliu;
-(NSDictionary *)raportIntreData:(NSDate *)dataInitiala siData:(NSDate *)dataFinala;
-(NSArray *)luniDisponibileIntreData:(NSDate *)dataInitiala siData:(NSDate *)dataFinala;
-(NSArray *)aniDisponibiliIntreData:(NSDate *)dataInitiala siData:(NSDate *)dataFinala;
-(NSArray *)vectorDateIntreData:(NSDate *)dataI siData:(NSDate *)dataF;
-(void)salveazaInFisier;
-(void)incarcaDinFisier;
+ (dataBase *)shareddataBase;


@end

And here is the .m file

#import "dataBase.h"
#import "SynthesizeSingleton.h"


@implementation dataBase
@synthesize inregistrari;


SYNTHESIZE_SINGLETON_FOR_CLASS(dataBase);


-(void)adaugaInregistrareCuData:(NSDate *)data siValoare:(NSNumber *)suma caVenit:(BOOL)venit cuDetaliu:(NSString *)detaliu{
    NSNumber *v=[NSNumber numberWithBool:venit];
    NSArray *input=[NSArray arrayWithObjects:data,suma,v,detaliu,nil];
    NSArray *keys=[NSArray arrayWithObjects:@"data",@"suma",@"venit",@"detaliu",nil];

    NSDictionary *inreg=[NSDictionary dictionaryWithObjects:input forKeys:keys];

    if(inregistrari == nil) {
        inregistrari=[[NSMutableArray alloc ] initWithObjects:inreg,nil];
    }else {
        [inregistrari addObject:inreg];
    }


    [inreg release];
    [input release];
    [keys release];

}

It made it to the end of that adaugaInregistrareCuData ... ok . said the array had one object ... and then crashed
