Layer Control Output

[CuraMarketing]

Hi,

with the recent update 16.1 they added a new Expressions Editor which is great but it looks like the also updated some of the syntax again.

With the Layer Control it used to give a error when there was nothing selected. So I added a try catch statement to get an output when nothing was selected. This no longer works. When you select nothing there will be no error.

I use a text layer to ouput the content of the Layer Control. In the legacy engine it gave you  [OBJECTLAYER] but now it gives you the name of the selected layer. But with none selected it gives you an empty text layer. I tried to get the output with 0, false and "" but nothing works.

Does anybody know what the ouptut of a Layer Control set to None is now?

Kind regards

I found a fix, but I don't know if it is the correct way to code this.

Instead of

var inputLayer = effect("Box Controls")("Parent Layer");

I need to add name at the end

var inputLayer = effect("Box Controls")("Parent Layer").name;

So it still outputs an error and the old try/catch statement still works.

But I'm still interested how it would work properly or what other methods i can use instead of name.
