How to fix the Flex debugger issue

Many a times we get this error message saying flex-debug not found and won't launch the debugger. The solution which I found is first get the flash unistaller, and then install the debugger version of flash player, it will start working as before.
The link for the flash uninstaller is as below

One its done, installer the debugger version which you can find in the link below:

This shall sort out our issue of the debugger not getting launched.

Copying from one array collection to another without keeping reference

private var List:ArrayCollection = new ArrayCollection;
private var duplicateList:ArrayCollection = new ArrayCollection;

// to get the data for the first Array Collection
eventList = eventStore.getData();

// copy it to the other Array Collection
for(var z:int =0;z{
if(List.getItemAt(z).view == 1)
duplicateList.addItem(List.getItemAt(z));
}
