Hi Chris,
thanks for the answer... my heart starts beating again. I get an error with your code on my laptop:

% Expression must be a structure in this context: <OBJREF (<ObjHeapVar4(IDL_CONTAINER)>)>.
% Execution halted at: TEST_JUNK::MYMETHOD 4 F:\Test\testobjects.pro
% TEST_PROPERTY_ON_OBJECT 11 F:\Test\testobjects.pro
% $MAIN$

I'm running IDL 8.2.0, Build id: 20120410 (from the help window).

I guess this is a beta version and tonight I will update. At least I know that the code I've written does not need major rewriting/mending...

Thanks again.

Cheers,
Helder
