[flexcoders] Measuring a vbox after I add children to it

[tchredeemed]

I add children, and only Text or Spacer, to a vbox.

After I have added them, I want to get the height of the vbox.

However, when I call vbox.height, it gives me 0.

If I call the measure() method, same problem, measuredHeight, same
problem.

Any ideas?
