NSFormatter and NSTokenField and setting the maximum length

Question

I would like to use a custom NSFormatter to judge the length of a string inside of a NSTokenField.

I have implemented the NSFormatter and hooked it up within the xib and all that, now when I get to running my application with the formatter inplace connected to the NSTokenField I get this error:

2011-12-31 18:15:11.761 MyApp[4706:a0f] -[NSCFArray length]: unrecognized selector sent to instance 0xf4a530
(gdb) describe 0xf4a530
Undefined command: "describe".  Try "help".
(gdb) p 0xf4a530
$1 = 16033072
(gdb) po 0xf4a530
<NSCFArray 0xf4a530>(
{
    Format = "%01d";
    FormatIndex = 0;
    Name = "$Counter$";
},
{
    Format = "";
    Name = hey;
}
)

Now I understand that indeed the textcell being evaluated contains an array of items so I will need to probably turn these to a string but the place where this is erroring in my code is here:

//Set this so that user can't enter a super long amount and overflow the character array lower in the engine. 
    [fieldFormatter setMaximumLength:40];

Im just evaluating the fieldFormatter object and setting its member variable of int to 40... really shouldnt be evaluating the text yet... right?
