Storing strings and integers in a single GWT array

Question

It seems like this should be relatively simple, but apparently not so much. I can't figure out for the life of me how to store strings and integers in an array in GWT. What data type do you use? If I use JsArrayString, it throws an IllegalArgumentException when retrieving an index containing a number. I obviously can't use JsArrayInteger (I have strings). JsArray requires a type, of which I have no idea what to use (if it can be used), I've tried String but get the same results.

The data being retrieved is from a script page and it does not have the ability to distinguish between strings and ints (Coldfusion).

Answer 1

I think you can use Object as your type. You'll have to box your primitives (int) in the Integer class if it doesn't do it automatically for you. You will also have to do some type checking after you grab what's in the array.

Answer 2

It's kinda clunky, but you could always do some brute-force determinations of whether a given value is an int or string:

<cfset val1="one">
<cfset val2="1">
<cfif int(val(val1)) eq val1>int<cfelse>string</cfif>
<br />
<cfif int(val(val2)) eq val2>int<cfelse>string</cfif>

This should give you

 string
 int

Answer 3

GWT does not currently have the functionality to parse an array structure that contains two different types of data unless in strict JSON form (not as part of a JSON structure in an array passed from ColdFusion apparently).
