OOP derive comm.CRCGenerator

I try to derive the CRCGenerator of the comm toolbox.
See: sample code
classdef crc < comm.CRCGenerator
properties (Nontunable)
CRCName
end
end
The result is, that the new property CRCName remains hidden in disp() but is shown in properties().
I'm using MATLAB Version: 7.14.0.739 (R2012a) and Communications System Toolbox Version 5.2 (R2012a).
>> a = crc(); >> disp( a );
a =
System: lte.generic.crc
Properties:
Polynomial: [16 12 5 0]
InitialConditions: 0
CheckSumsPerFrame: 1
>> properties( a );
Properties for class lte.generic.crc:
CRCName
Polynomial
InitialConditions
CheckSumsPerFrame
>>

I'm not a MATLAB class system expert, but I wonder if you need to overload DISP for your class. You could try that and see if it resolves the issue.

With the overloaded disp() function it works, thanks.
classdef crc < comm.CRCGenerator
properties (Nontunable)
CRCName
end
methods
function disp( obj )
builtin('disp', obj );
end
end
end
