Array values from Rich Client

I need to pass a list of employee status codes into the flow and put them in a simple array.

From the log:

FromStatusCodes = A1,A2,A3,A4,A5,A6,A7,A9,MD,ML,RW,WC - this list was hard coded in the start node of the flow ["A1","A2","A3","A4","A5","A6","A7","A9","MD","ML","RW","WC"] - field is defined as array

  testInt1 = A2 - from FromStatusCodes[1];

ToStatusCodes = ["A8","SV"] - this list is coming from rich client - field is defined as string
testArray = [Ljava.lang.Object;@78d48440 - field is defined as array and the value is ToStatusCodes
testInt2 = undefined - from testArray[2];

It appears that it isn't possible to take a string value from rich client configuration and convert it to an array.  Is that correct?

Thanks!
