Flex 4.5.1 Issue

When I run the command "JSInterface.initialize(this);" in Flex 4.5.1, I get the 
following error:

----------------------------------------------------------------

Hello,

I have been able to get JSInterface to function correctly by adjusting the 
examples provided.

Instead of using:
JSInterface.initialize(this);

The following can be used:
JSInterface.initialize(this.root);

This issue can be marked as resolved.
