Style issues aside, I found your problem:
>
> public void init()
>{
>
>resetactuallftorealextent();
>
> GraphicsDataList graphicsList = new GraphicsDataList();
>
>
should be
public void init()
{
resetactuallftorealextent();
graphicsList = new GraphicsDataList();
...
You have declared a new local variable with the same name as your class
instance variable. When the init() method terminates so does this local
version. The problem you experienced but failed to describe was an
endless series of NullPointerException stack traces being thrown and
discarded behind the scenes.
And please refactor the code to use camelCase names. Just scanning
through it gave me and anyone who looked at it headaches.
