ComboBox Problem

[Jhon Carlo]

I'm trying to add some item to a combo box but I get the error message below:

//My script:

MyCombo.addItem({ label: "MyItem1"});

MyCombo.addItem({ label: "MyItem2"});

Why?

Any hint?

Thank you.

//the error message:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

that's an animate cc 2017 bug.

either use an earlier version of animate or create your own combobox.

Thank you kglad.

But I don't understand why adobe give this component if it doesn't work.

Why don't give a good one?

i don't have an answer for that.

my guess is something new in animate 2017 (like adding components to canvas) caused a problem that no one detected.  hopefully that will be fixed in the next update.

Sorry for the bump, but did Adobe solve this?
