PDFView in modalwindow

Question

I have a Cocoa application that opens a modal window, that loads loads a pdf from a ftp server, and displays it in a PDFView. I use ARC

    PDFViewerWindowController *pdfViewerWindowController = [[PDFViewerWindowController alloc] initWithWindowNibName:@"PDFViewerWindow"];
    [pdfViewerWindowController setDocumentForUrl:url];
    [NSApp runModalForWindow:[pdfViewerWindowController window]];

and here is the setDocumentForUrl:

-(void)setDocumentForUrl:(NSString *)url
{
    NSString *urlString = [NSString stringWithFormat:@"ftp://192.168.32.11%@", url];
    pdfDoc = [[PDFDocument alloc] initWithURL:[NSURL URLWithString:urlString]];
    [pdfView setDocument: pdfDoc];
}

I get this error (this does not happen all the times):

I'm not sure it's possible to use a PDFView in a modal window. Does it work if you use the same code in a normal window?

It works on Snow Leopard with no problem, but it doesn't work all the time on Lion (I only get this error some times) – Radu Paise Jun 23 '12 at 08:04
