MATLAB: Does ISFIELD always return FALSE when querying a user-defined class in MATLAB 7.7 (R2008b)

classisfieldsMATLABmcosoop

When I use the function ISFIELD on a MATLAB class object, it always returns false, even when I know that the queried property is there.
The class definition includes a property called 'myproperty'
classdef myclass
      properties
          myproperty = 0;
      end
end
When I check the presence of a property as follows:
x=myclass
isfield(x,'myproperty')
ISFIELD always returns a FALSE
 ans =
       0

Using ISFIELD on a user defined MATLAB class is not supported in MATLAB 7.7 (R2008b).
As a workaround, use the following to determine if a property exists for a class:
any(strcmp(properties(x), 'myproperty'))
