Hey guys,

I have found this script on the internet (link) and it's exacty what I need, however I'm getting this error when I try to run it "null is not an object". Can anyone take a look?

 

var myDoc = app.activeDocument;

var myPages = myDoc.pages;

var myMasterPage = myPages[0].appliedMaster.pages[0];

var myItems = myPages[0].allPageItems;
for (y=0; y<myItems.length; y++) {
    var myItem = myItems[y];

    if (myItem.constructor === TextFrame) {
        myItem.override(myMasterPage);
    }
}

 


Thanks,
Rogerio

You don't override a live page's items. You override the master page items to the target page (passed in the override function). As in:

var myDoc = app.activeDocument;

var myDoc = app.activeDocument;
var myPages = myDoc.pages;

var myMasterPage = myPages[0].appliedMaster.pages[0];

var myItems = myMasterPage.allPageItems;
for (y=0; y<myItems.length; y++) {
    var myItem = myItems[y];

    if (myItem.constructor === TextFrame) {
        myItem.override(myPages[0]);
    }
}

Remember to put the myItem.override() inside a try/catch block. This is because it will throw an error if the item has already been overridden.

Also take note that myItem.override(targetPage) tends to shift the item when new pages have been added or for other obscure reasons.

 

A generic bugfix is based on the targetPage.masterPageTransform matrix, whose nonzero translation components typically reflect the undesired shift:

 

// Fixed override()
var mx = targetPage.masterPageTransform.matrixValues.slice(-2);
mx[0] += 'pt';
mx[1] += 'pt';

try{ myItem.override(targetPage).move(void 0, mx) }
catch(_){ }

 

Best,

Marc
