Can someone fix this jsfl bug？

[kqskcm]

an.getDocumentDOM().enterEditMode('inPlace');                                                          

var layerIndex = fl.getDocumentDOM().getTimeline().findLayerIndex("layer_3");

an.getDocumentDOM().getTimeline().setSelectedLayers(layerIndex[0], true); 

an.getDocumentDOM().setElementProperty('firstFrame', 5-1);                                          

an.getDocumentDOM().exitEditMode();

how can you enter edit mode with nothing selected?  that should throw an error.

or do you select something manually before running the jsfl?

and what is

an.getDocumentDOM().setElementProperty('firstFrame', 5-1);  

[kqskcm]

before running jsfl，Only the entire symbol on the stage can be selected

[kqskcm]

The symbol contains 4 layers

[kglad]

ok, so layer_3 is selected and then you're executing

an.getDocumentDOM().setElementProperty('firstFrame', 5-1); 

which makes no sense:  a layer isn't on stage so it's not an element.

what are you trying to do to layer_3?

[kqskcm]

Yes！

[kqskcm]

I am only able to select layer_0 on the stage，If you can directly choose layer_3 first, then the problem is much simpler

[kglad]

are you converting layers to symbols?

[kqskcm]

are symbols

[kglad]

what's the purpose of selecting a layer?

[kqskcm]

[kqskcm]

layer_3 contains 5 keyframes
