Only drag one component column and tap "Set" will cause undefined

[tobatha]

If setup multiple components, say 3, and set input value to "" Whenever the picker is brought up, if i just tap "Set", all component values will be fetched

BUT if i only dragged 1st component column, and then just tap "Set", the other 2 component values will be "undefined" in input.

Official demo can also reproduce if u set all values to "" in AnyPicker-Select-Multi-Component.htm
