[flexcoders] Tree / dataDescriptor / debugger

[nwebb]

Hi,

has anyone had trouble viewing properties of the Tree components data
descriptor, when debugging?

I just noticed this issue when looking at a script. The descriptor is listed
in the Variables view, but does not expand to show any properties.
I was able to recreate the issue easily enough and wondered whether it needs
reporting or not.
To test it yourself:

1. Copy and paste the following code in to a new project.
2. Put a breakpoint on line 23 (the closing bracket of the onComplete
method)
3. Run

You can see that the descriptors hasChildren is true. I also created a
variable showing the children, but still the descriptor won't expand in the
Variables view.
Seems odd. I have tried rebooting, cleaning the project etc etc. Just about
to check I have the latest debug player. Seems to consistently fail
