QUESTION
I'm using both Scala.JS and Akka.JS to learn about client-side, actor-based apps. When the user selects a country from a list of countries, a list of cities in that country is constructed. This part works fine.
However, some countries are listed as having only one city (E.G. Hong Kong contains only Hong Kong), so when I display the list of cities, I'd first like to check the length of the city list (which is of type js.Dynamic). If its >1, I'll add a non-selectable placeholder "Select a city" to the dropdown list and then build the city list. As long as I do this arbitrarily, everything works fine.
In spite of the fact that I can quite happily map
a function across the cityList
of type js.Dynamic
, it seems that testing the length of cityList
is not something that can be done directly, even though the cities
JSON object is an array:

The object you are attempting to access the property of 'scheduler$3' appears to be null. Try verifying that it's source is properly retrieved. Can you provide more information and I could maybe give a more detailed answer?

Answered 2017-Apr-20 at 20:30Sorry for the very late answer, yes it used to be an issue but akka.js is now (version 1.2.5.0
) using scala-java-time itself, and the two libraries got a reconciliation.
