I’ve created a singleton class to load in that initial states for certain modules. This class loads in 2 XML files, first a global.xml, which contains a pre-set set of states for the entire project, is loaded into one array. It then loads in the appropriate xml file for the module that was chosen into another array. I then have the class copy the first array into an array called stateArray then overwrites items in the stateArray with the values in the 2nd array.
I’ve also added a function to reset the class when the user selects a new module.
This class works fine the first time I select a module the first time. However, when I go to select a second module, my code doesn’t seem to be calling the reset function properly. Could someone please look at my code below and tell me what I’m doing wrong?

And here is the code within the main program:
[AS]
ModuleDrop.onChange = function() {
_global.stateManager.resetInstance();
_global.stateManager = null;
//Copied from NAV button!
_global.currentUnit = “”;
currItem = ModuleArr[Number(eventObj.target.value)];
currModule = currItem.split(",")[1];
_root.currentInit = currModule;
_global.currentInit = “./InitFiles/”+currModule+".xml";
_global.stateManager = stateManager.getInstance(_global.currentInit);
}
[/AS]
I really appreciate all the help I can get.
