(JavaScript API 1.3 for Office) Custom Properties add method

问题

Here's a link tho what made me start digging into custom Props again.

I can see that my customProperties are 0 so i assume getCount is somewhat working, even though I'm accessing it through items.length and not customProps.getCount()

Is this still intended or am i just not doing it right and it's possible doing as in the MS Office Documentation

Now the main part of my question, the add method. Whatever i try it crashes and i get an exception. Can i assume add method is still not properly implemented?

This is all on Word API.

Any help would be appreciated. Thank you very much!

I verified this code does not crash Word and works. (assuming you are in latest builds, if your items.count works, this should too.

 Word.run(function (context) {
  context.document.properties.customProperties.add("PropertyName", 1234);
  return context.sync();
  }) 

If this does not work, please reply with your build number. thx.

Thank you all, I was on my laptop and still needed an update. Newbie mistake. I've tested that code and it works.
