Can't get acces to text on path embedded into rectangle

>> app.selection[0].graphicLines[0].textPaths[0].contents
medium

How to figure it out? Try this:

function id(o) { var i, j, k=[];
  for (i in o) {
    if (o.hasOwnProperty(i)) { k.push(i) }
  }
  k.sort();
  for (i=0; i<k.length; i++) {  j=k; try {
    if (app.selection[0].length) {
      $.writeln(j+"\t"+app.selection[0].length);
    } catch (e) {  }
  }
}
id(app.selection[0])

which gives you:

allPageItems     1
geometricBounds     4
gradientFillStart     2
gradientStrokeStart     2
graphicLines     1
pageItems     1
paths     1
preferences     10
splineItems     1
visibleBounds     4
undefined

and then it's all downhill from there
