   @brianraymes just to be clear: 
   
   are you saying that the issue is caused by this code in the setter:
   `warning = config.someProperty.length == 0;`
   
   when either the value of 'config' ('this._config') or (this._config.someProperty) is null ?
   
   Did this same code work in Flex?
   
   Otherwise, my first inclination would be to code the setter with null safety, because if you were to set it with null values via regular actionscript it would also error (null value or null value.someProperty).
   
   `warning = value && value.someProperty ? value.someProperty.length == 0 : false` (or whatever logic makes sense for warning to be true or false in absence of value/ value.someProperty )
   
   However, if you can confirm that this did work in the past as-is in Flex, then I will try to figure it out.
