how to split a string in log file

[wvxvw]

This is how Array.toString() works it joins the results with commas. You can alter it like this:

<mx:String id="foo"></mx:String>
<mx:Label text="The delimited string is:{foo} The result is: {arr.join(foo)}" id="myLabel"/>

Or you can manually build the desired string by adding items from the array together ( just like in the example I posted; maybe you'll run over a situation when you don't want to display the elements of the entire array at once ).
