Error when trying to select two text frames from a layer with script (Error number: 53762)

Mark's point was (I think) that you shouldn't try to select those frames and go through menu actions, but refeerence those frames directly.

To copy the frames on the Nomes layer to another document, use this:

app.documents[0].layers.item('Nomes')
  .textFrames
  .everyItem()
  .duplicate (app.documents[1].pages[0]);

This assumes your one-page document. To copy the frames on a given page, collect the frames on that page on that layer and duplicate those. Placing them on a particular layer in the target document requires an additional step.

Hi @Breno25791737ot2o, this is a conventional approach, I think. Does it help in your case?

- Mark

function main() {

    var sourceDoc = app.activeDocument;
    var layerName = "Nomes";
    var sourceLayer = sourceDoc.layers.itemByName(layerName);

    if (!sourceLayer.isValid)
        return alert('No Layer called "' + layerName + '".');

    sourceLayer.locked = false;
    sourceLayer.visible = true;

    sourceDoc.selection = sourceLayer.textFrames;

};
app.doScript(main, ScriptLanguage.JAVASCRIPT, undefined, UndoModes.ENTIRE_SCRIPT, 'Your Script Name');

Maybe your document is corrupted - try IDMLing - export as IDML, open, save with a new name - do not overwrite your original file.

You can't select objects on multiple spreads - only same page / spread.

If you can copy one-by-one - this means that neither layer or those objects are locked? 

What is the exact name of the action you are trying to invoke?
