Proper way of implementing page transition?

Question

Hi, I have a Flex application that uses multiple pages,
joined by a ViewStack. Page transition is handled by the attached
function (which, as the comment indicates, causes massive memory
leak). This function is called in about 40 locations throughout the
Flex application. The function calls removeAllChildren and
createComponentsFromDescriptors so that pages with forms are reset
to blank, as opposed to having to manually go through each
component in a page and resetting them to their initialized state.
Preferably, I would like to preserve the form resetting behaviour
of this function but cut the memory leak. Any advice on what the
best solution to this problem would be?
