Hi list,

I am new to the cocoa development. I have some question to NSArrayController

I add an object to the controller array like this:

CODE ##############################################################################

NSMutableDictionary *theDicRow = [NSMutableDictionary dictionaryWithObjectsAndKeys: @"Text A", @"colA", @"Text B", @"colB", nil ];

[myArrayController addObject:theDicRow];

CODE ##############################################################################


This works great and do its job.
I can call the object from the content an get the log result like this:

CODE ##############################################################################

[2355:10b] (
        {
        colA = "Text A";
        colB = "Text B";
    }
)

CODE ##############################################################################

Well, this is okay.


If I do this:

CODE ##############################################################################

NSMutableDictionary *theDicRow = [NSMutableDictionary dictionaryWithObjectsAndKeys: @"Text A", @"colA", @"", @"colB", nil ];

CODE ##############################################################################


The result is:

CODE ##############################################################################

[2355:10b] (
        {
        colA = "Text A";
    }
)

CODE ##############################################################################

But I wanna have the empty string back. So it seems, that the empty string is converted to nill and the controller is killing them out. How can I change this reaction with empty strings? I need this @"" Strings.

Thank you for information!
