Mmmmm, I don't see it clearly either... I *think* the correct thing to do is what Max pointed out, and make Demeter happy on the way. What if materialColetado's structure changes? If you use that level of indirection, you'd have to change your fields declaration AND any other code that needs that attribute from an "analise" instance, if you code it as a property, you just need to modify the getter.
I think it wouldn't be *that* easy to implement either, as you'd have to traverese the full path to the desired attribute... what if one of the intermediary attributes is a callable? (well, ok, it could be a property...). it remind's me of Cheetah's name lookup mechanism (though maybe my memory is not good at all :). I think it's too much magic for just a little datagrid ;) Disclaimer: Haven't read the code before writing the last paragraph so I might be *way* wrong... :D Regards, Alberto
