[JS IDCS5] Running through all tables and place textFrame

Question

I wan't to place textFrames below all the tables within a document.
#target indesign;
var myDocument = app.activeDocument;
var myTables = myDocument.stories.everyItem().tables;
for(var i=myTables.length-1; i>=0; i--){
           // var myFrame = myTables[i].insertionPoints[0].textFrames.add();
           // the above line does not work......
How do I get the insertionPoints of the tables, so textFrames can be added at that point?

Answer 1

Tables have a property storyOffset, which is an insertion point. myTable.storyOffset is the insertion point immediately before the table. The ip after the table you can get your hands on like this:
myTable.storyOffset.parentStory.insertionPoints[myTable.storyOffset.in dex+1];
Now I get the following error:
JavaScript Error!
Error Number: 55
Error String: Object does not support the property er method 'storyOffset'
Engine: main
Source: myTables.storyOffset.parentStory.insertionPoints[0].textFrames.add();
What is wrong?
