add property to object?

Question

With Indesign scripting, why can't I add properties to an object? I get an error > Object does not support the property or method 'foo' items = b.items(b.layer("s_labels")); for (var i = 0; i < items.length; i++) { items[i].fit(FitOptions.frameToContent); items[i].foo = "bar"; // other attempt items[i]["foo"] = "bar"; }

InDesign 'objects' are not normal JavaScript objects. You cannot just stuff your own properties into them.

You would undoubtedly get a more complete answer if you post the question to the Adobe InDesign Scripting Forum.
