A good way to debug this kind of stuff is to check what InDesign thinks myVar and its parent are:

alert (myVar.constructor.name+” / “+myVar.parent.constructor.name);

You can always try myVar.parentTextFrames[0] — this will point directly to the frame holding your text.

Theoretically, you ought to be able to change the contentType of a frame's properties from TEXT_TYPE to UNASSIGNED, but I remember having wrestled with this before. It might be ID simply does not believe you when you want to change the type of a Text Frame …
