How to use jsfl to lock all layers within a symbol

Hi,

Basically, you can lock all layers in particular timeline with this JSFL function:

timeline.setLayerProperty( "locked", true, "all" );

But you need to define which symbol you interested in?
- selected on the stage
- selected in the library
- or you need to find the symbol by its name or some of the names of its instances and so on.
