Issue with setting createPrimaryTextFrame in a documentpreset

> So do you mean to say that once the preset is created we can't change the createPrimaryTextFrame attribute value?

That's the thing with creation properties. You can't change them once they exist. There's a hack to change a primary frame to a non-primary one: type any character in it then remove that character. I'm not aware of a hack to change a frame to a primary one.

Hi @Manan Joshi , Also, it isn’t throwing an error, but your add("MJ") needs to be add({name:"MJ") if you want the preset to be named MJ. Try this:

var p = false
for (var i = 0; i < 5; i++){
    var dp = app.documentPresets.itemByName("MJ")
    if (!dp.isValid)
        dp = app.documentPresets.add({name:"MJ"})

    dp.createPrimaryTextFrame = p
    $.writeln("Value to set " + p + " Value set " + dp.createPrimaryTextFrame + " Preset Name " + dp.name);

    /* returns: 
    Value to set false Value set false Preset Name MJ
    Value to set true Value set false Preset Name MJ
    Value to set false Value set false Preset Name MJ
    Value to set true Value set false Preset Name MJ
    Value to set false Value set false Preset Name MJ */

    p = !p
}

primaryTextFrame is a creation property, you have to do it when you create the document. Something along these lines:

app.documents.add ({
  documentPreferences: {
    createPrimaryTextFrame: true,
    // Any other properties
  }
});
