  Get Layer of a property via expression

  Posted by Arne Münch on July 8, 2021 at 12:20 pm

  Hi there.
  In Scripting there is this elegant method to find a layer of a property by

  property.propertyGroup(property.propertyDepth)

  I dont find anything like this for the usage in expressions, because propertyDepth doesnt seem to work here. Any solutions?

  It’s not elegant, but you can do something like this:

  p = thisProperty;
  while(!(p instanceof Layer)){
    p = p.propertyGroup(1);
  }

  Hallo Dan

  Thanks so much, works perfect again.

  Meanwhile I had figured out this far less elegant way;)

  I used try{} and ended with the index of the layer.

  p = thisProperty;
  for (i=0; typeof(layerIndex) != "number"; i++){
      try{layerIndex = p.propertyGroup(i).index;
      }catch(e){};
  }

  I will change my expression to your way…
