How to fill a tableview with sudzc? (My property dont work)

Question

I have a class that uses sudzc. All works fine, with NSLog I can watch the data of my web services, but when I want to use an array and then use that array in other place, the property is null. I want to fill a table view with the data of the web services, but I can't, How could do it?

This is my class

My data is

@property (nonatomic, retain) NSMutableArray *myData;

Thanks

Firstly, this is doing nothing for you:

self.myData = [[[NSMutableArray array] init] autorelease];

...

self.myData = unidadOrganizacional;

You are assigning myData then immediately reassigning it.

Skip the first initialization and just do this:

self.myData = [unidadOrganizacional mutableCopy];

I suspect you are losing the pointer to the unidadOrganizacional array at some point and that is why you are getting null for myData.

Personally though I would just do this initialize myData in the viewDidLoad call and then add the objects to myData directly:

- (void)viewDidLoad
{    

    self.myData = [[NSMutableArray alloc] init];

    // I want to fill the table view but dont work
    EWSEmpresaWebServiceSvc *service = [[EWSEmpresaWebServiceSvc alloc] init];
    [service ConsultarUnidadesOrganizacionalesPorEmpresa:self EmpresaId:self.empresaID];
}

and then:

- (void) ConsultarUnidadesOrganizacionalesPorEmpresaHandler: (id) value {

    // Handle errors
    if([value isKindOfClass:[NSError class]]) {
        NSLog(@"%@", value);
        return;
    }

    // Handle faults
    if([value isKindOfClass:[SoapFault class]]) {
        NSLog(@"%@", value);
        return;
    }               


    // Do something with the NSMutableArray* result
    NSMutableArray *result = (NSMutableArray*)value;

    for (int i = 0; i < [result count]; i++)
    {
        EWSUnidadNegocio *empresa = [[EWSUnidadNegocio alloc] init];
        empresa = [result objectAtIndex:i];
        [self.myData addObject:[empresa Descripcion]];
    }
}

-(void)onload:(id)value
{
    // Handle errors
    if([value isKindOfClass:[NSError class]]) {
        NSLog(@"%@", value);
        return;
    }

    // Handle faults
    if([value isKindOfClass:[SoapFault class]]) {
        NSLog(@"%@", value);
        return;
    }               


    // Do something with the NSMutableArray* result
    NSMutableArray *result = (NSMutableArray*)value;

    for (int i = 0; i < [result count]; i++)
    {
        EWSUnidadNegocio *empresa = [[EWSUnidadNegocio alloc] init];
        empresa = [result objectAtIndex:i];
        NSLog(@"%ld -- %@", [empresa Id], [empresa Descripcion]); // With this I can watch the data in the console
        [self.myData addObject:[empresa Descripcion]];

    }
}

You may want to clear out myData before the ConsultarUnidadesOrganizacionalesPorEmpresa call, I'm not really sure what the different between that and onload is really. It looks like they are duplicates of each other.

Good luck!
