Sorry to post only when there is an issue. I appreciate the work that you have done on the App Builder.
I am developing a multi-select calendar widget that previews and functions as intended in the app builder. When an instance of it is created in the Wix Editor, there are two problems. Though there are five properties, the settings button does not appear. When previewing it in the editor, it returns the "cannot read property 'type' of undefined" error and the onReady calendar setup code does not fire.
I've tried deleting and re-adding the five properties and the one function, but it makes no difference.
Thanks in advance for looking into this.
