Hi Mike,

Just following on this, been awhile and an old post......but be nice if you can review my code for this history state and have it work right.

This code for suspending history to once undo state, it seems to work not in the right way....where it creates a secondary text layer that is not needed.... See my attached file for what i mean. Ideally, i'd like to undo only once when it creates the text but it seems there's many state history inbetween that is not being enabled for undoing.
Code: Select all if (app.documents.length > 0) {
var myDocument = app.activeDocument;
myDocument.suspendHistory("this will show up in the history panel", "multiselectfontreader()");
};
//
function multiselectfontreader() {

app.bringToFront();
main();

function main() {
if (!documents.length) return;
var selLayers = [];
selLayers = getSelectedLayersIdx();
for (var a in selLayers) {
makeActiveByIndex(selLayers[a], false);
//amend to suit.
readTextLayer()
}
}

function getSelectedLayersIdx() {
var selectedLayers = new Array;
var ref = new ActionReference();
ref.putEnumerated(charIDToTypeID("Dcmn"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt"));
var desc = executeActionGet(ref);
if (desc.hasKey(stringIDToTypeID('targetLayers'))) {
desc = desc.getList(stringIDToTypeID('targetLayers'));
var c = desc.count
var selectedLayers = new Array();
for (var i = 0; i < c; i++) {
try {
activeDocument.backgroundLayer;
selectedLayers.push(desc.getReference(i)
.getIndex());
} catch (e) {
selectedLayers.push(desc.getReference(i)
.getIndex() + 1);
}
}
} else {
var ref = new ActionReference();
ref.putProperty(charIDToTypeID("Prpr"), charIDToTypeID("ItmI"));
ref.putEnumerated(charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt"));
try {
activeDocument.backgroundLayer;
selectedLayers.push(executeActionGet(ref)
.getInteger(charIDToTypeID("ItmI")) - 1);
} catch (e) {
selectedLayers.push(executeActionGet(ref)
.getInteger(charIDToTypeID("ItmI")));
}
}
return selectedLayers;
};

function makeActiveByIndex(idx, visible) {
var desc = new ActionDescriptor();
var ref = new ActionReference();
ref.putIndex(charIDToTypeID("Lyr "), idx)
