I read from Reference choice list using AJAXReferenceChoice doesn't display all choices? that you need to change the property glide.xmlhttp.max_choices in order to show more items in the choice list. Default is 15 items. I changed this property to 20 but it doesn't change my number of choices in the drop-down. Do I need to do something else in order for this to have effect ?
It sounds like the property may not be behaving as it should. I recommend reaching out to customer support. I'll be interested to hear what they have to say.
