Here is my pureMVC presentation to the Capital Area Flex User Group

Would love to hear your comments.

Hello,
I am facing this strange behavior with a popup. I have an application that
pops a new window, and when the user clicks on a button in that popup, it
goes and gets some data from the database, then the mediator updates the
dataProvider of a combobox and calls the function combobox.open().  The
issue is if the user opens and closes the window 2 or 3 times, there are 2
or 3 data providers on top of each other. To see this clearly,  open a
popup, and move it somewhere, then close it, do this 2 or 3 times, every
time moving the popup window somewhere different on the screen, then press
the getdata button, you will see the strange behavior attached in the screen
shot. I am not sure if I am doing something wrong or is this a pureMVC issue
or a flex issue. I created a simple project (attached) demoing that issue.
