.createTOC() every time use createBookmarks = true

Hello @all,

I have a problem with the following code to auto-update my TOCs in InDesign CS4:

var myDocument = app.activeDocument;

alert("createBookmarks: " + myDocument.tocStyles.itemByName("Kapitel 1").createBookmarks);  // --> this show me "false"

var myStory = myDocument.createTOC(myDocument.tocStyles.itemByName("Kapitel 1"), true /*replacing*/);

After this action I have entries from the TOC ("Kapitel 1") in my pdf bookmark? Why?

I also tried for test purpose the following:

myDocument.tocStyles.itemByName("Kapitel 1").duplicate();

This copy of my TOC has the option "pdf bookmars" on "true"?!

How can I force, that I get NO createBookmarks for this TOCs?

If I use manually "layout-->toc-formats-->update TOC" it works fine for me.

Regards,
Jessi
