AE Script : How to access to a mask property : "Source" - "Masks" - "Effects and Masks"

I want to modify from a script a property of a filter that points to a layer.
This type of property has two values:
1) The layer name
2) the choice between "Source" - "Masks" - "Effects and Masks"
To modify the 1st property I do: property("Layer").setValue(index), and it works 🙂
but how to change the 2nd one ?

It's not possible. The only way to "set" the "Source / Masks / Effects & Masks" dropdown is to save an ffx preset of the effect with the dropdown set. Include it in your script as a binary string, then create the ffx file for the user at some location on their computer, and apply the preset using Layer.applyPreset().

Thank you Constantin for this idea.

Still no solution to this problem other than going through an ffx?

I'm not aware of any way to get to "Source" - "Masks" - "Effects and Masks" via scripting.

Dropdown controls are simply enumerated arrays. A simple .setValue([2]) could do the trick.

OK but what to put before the .setValue([2]) to say that we want to access the "Source"part (B) ?
The logical solution would be to be able to :

access A with : property("Layer")[1].setValue()
access B with : property("Layer")[2].setValue()

but it doesn't work 😞
If we can't access to B to change the Source, one solution is to precompose the layer, transferring the attributes to the new composition !
