Create primaryTextFrame

[Mario Fritsche]

Hello,
per script I want to create a new MasterPage and create a primaryTextFrame on it? TextFrame is no problem, but I can't get it set to primary.

Click on the symbol on the upper part of the left edge of the text frame once. It will change it to a primary text frame.

Hello,
yes, but I want to create it via JavaScript.

Why do you want a script, when a single click will solve your problem?

It is only a small part of a script. I want to create a new document with several pages. For this I need a primaryTextFrame for different MasterPages

There's a property createPrimaryTextFrame, which is a creation property, that is, you have to set the property when you create a document. You can't change an existing frame to a primary frame. here's how to use it:

doc = app.documents.add ({
  documentPreferences: {
    createPrimaryTextFrame: true,
    // And whatever else
  }
);

The MasterSpread object has a primaryTextFrame property. I've enver used it but I would imagine it would be something like: 

myParentSpread.primaryTextFrame = myParentSpread.textFrames.add();

Nope, doesn't work: "Invalid object for this request".

Hmm, bug? If you have a PTF set on the parent, then mySpread.primaryTextFrame.isValid is true, but you're right, doesn't seem you can set it on the fly. Weird.

Definitely seems like a bug. Added it to user voice: https://indesign.uservoice.com/forums/601180-adobe-indesign-bugs/suggestions/46003087-masterspread-p...
