Flex error #2176 when using FileReference

The flash player 10 has new rules for UIA ( user initiated action ) so when I tried to use the FileReference save method I got the following error: Error: Error #2176: Certain actions, such as those that display a pop-up window, may only be invoked upon user interaction, for example by a mouse click or button press. After I made some research I found a very cool article here, but I didn’t found any workaround.

Dispatching a MouseEvent won’t work, because the user must interact with the application by clicking a mouse button or by pressing a keyboard key.┬áI found a way to get rid of this error by displaying a popup and let the user to click a button in order to force the user to ┬áinteract with the application.

					fileReference = new FileReference();
					fileReference.save("https://www.bogdanmanate.com", "test.txt");
