CEP panel - UndoGroup is not created
Dear all,
Long time lurker here, now I got stuck and can not find a solution. I hope someone can point me in the right direction.
Before I went into CEP panels, I could easily create an undo group.
// in jsx
app.beginUndoGroup("My Undo Group");
//adding layers here
app.endUndoGroup();
Now I moved to CEP panels where most calculations are done in my js or vue file. Functions in CEP contain loops which call the .jsx several times to add layers one by one. All the right layers, shapes and keyframes are added in the right order, all is fine there.
But I wish to put an Undo Group around all this. I have a hard time finding out how to achieve this. In the console log I see that beginUndoGroup, the adding of the layer(s) and the endUndoGroup are called in the right order. But File > Undo will only show me the individual actions.
I now start the doubt that I set up my script the right way, maybe I should gather all the evalScripts and call the JSX just once? On the other hand, I think it defeats a lot of other advantages. Anyway, I am quite lost here, but I assume I'm not the first one facing this problem.
I tried to simplyfy it here. Adding just one layer with undo group around it.
// in CEP
addLayers(){
let myLayer = evalScript(`addLayer()`);
return true;
},
mainFunction(){
var beginResult = evalScript('beginUndo();');
if (beginResult){
var layerResult = _this.addLayers();
if (layerResult){
var endResult = evalScript('endUndo();');
}
}
}
//in JSX
function beginUndo(){
app.beginUndoGroup("My Undo");
console.log('beginUndo() called');
return true;
}
function endUndo(){
app.endUndoGroup();
console.log('endUndo() called');
return true;
}
function addLayer(){
var comp = app.project.activeItem;
var layer = comp.layers.addShape();
console.log('addLayer() called');
return true;
}
Any pointer in the right direction is greatly appreciated!
