How to implement onMove?

[#1]

If I have a property of type array and allowMove is set to true. When I move an item the property panel is updated but I get this error

TypeError: undefined is not a function at Object.f.sortableOptions.onMove

I have tried to add sortableOptions to the definition of the array and to the items in the array but it doesn't work.

How can I fix this?

Cheers

I figured out a way to fix the problem. I don't no if it's the right way but it works.

I created a component based of the list component, but change the onMove function and changed the last row.

onMove: function(old_index, new_index) {
  if (new_index >= f.listData.length) {
        var k = new_index - f.listData.length;
        while ((k--) + 1) {
            f.listData.push(undefined);
        }
    }
    f.listData.splice(new_index, 0, f.listData.splice(old_index, 1)[0]);
    f.$emit("saveProperties");
  }
...
return a.addComponent("kfMeasureList", g), g

I used the new component in my extension and change the component property to kfMeasureList
