Subject Re: Rookie ArrayCollection Question
Date Thu, 29 Sep 2016 10:19:25 GMT
ArrayCollections are a complex data type  meaning they are passed around by
reference. You are actually passing a pointer to the array. The pointer
points to the memory location. You'll have to make a copy of the array.


Comps.dataProvider = compArrayCollection.source.concat();

Google passing by value and passing by reference to learn the difference
between how simple and complex data types are handled
