Does it appear correctly on screen but just not in the snapshot?  Maybe try 
using callLater to defer taking the snapshot

Alex,

I tried this with Flex 2.01 and it did not work properly. Still the same 
number. The updated code looks like:

currentNum += thisAmount;

lblNumber.text = String(currentNum);
this.validateNow();

Still get a grid of the same initial value.

Alex,

number. The updated code looks like:

currentNum += thisAmount;

lblNumber.text = String(currentNum);
this.validateNow();
