Will switching DAD cause problem...

Question

On our development box our DAD is pls/portal, our production box DAD will be pls/new. When we export our page group to the production box, will the export be successful even though some of the links will point to pls/portal in the HTML portlets, page links etc? If so, then can we change them once we import to our new box?
Thank you.

People don't typically keep a reference around to events once they dispatch them, so they are usually garbage collected.
But I suspect you mean "can adding a listener for a mouse event hold an object in memory?" The answer is "under the right circumstances."
If you have code like this in a parent MC:
myChild.addEventListener(MouseEvent.CLICK, onChildClick);
This will not hold either the parent or child in memory, because the reference is from the child (whose addEventListener function has been called with areference to onChildClick) to the parent (where onChildClick "lives"). If the parent is dereferenced, the child is dereferenced in most circumstances unless something else has gotten a reference to the child and not the parent. So you should avoid direct knowledge of the children of any of the MC's you're managing. If you have it, you should carefully release all such references when the parent is released.
If you have code like this in a child MC
parent.addEventListener(MouseEvent.CLICK, onParentClick);
That will indeed hold the child in memory (as long as the parent is referenced somewhere or is on stage) unless you can find a way for the child to figure out it should remove the listener. For example, I often create a cleanUp method in Classes that listen to ENTER_FRAME and other such events that will remove these types of listeners when the instance is REMOVED_FROM_STAGE. I won't say I don't ever listen to the parent like this, but I do actively avoid it and can't think of an instance off the top of my head where I do it.
