Question

I’m trying to get familiar with a legacy project. In one particular function, I have the code:

public function update(userObj:Object):void
{
    var comm2:CommManager;
    comm2 = CommManager.getInstance();
    comm2.statusManager.employeeStatus(employeeId);
}

Although I can put a breakpoint that catches, I am unable to trace into either of these two lines to view the corresponding code. In the first case, the top of the call stack reads:

comm::CommManager$/getInstance

In the next, the top of the call stack reads:

comm::StatusManager/employeeStatus

In both cases, I get a new line in the Output window:

Cannot display source code at this location.

How can I figure out where this code is coming from? I’m not aware of any external linking, but it certainly wouldn’t surprise me.

Addendum: Although CommManager.as has a matching API, I’ve added corresponding breakpoints inside of it which don’t catch. Also, if I rename the file, I get a compile error, telling me the CommManager type was not found. It’s as if CommManager.as is only partially being used. Although CommManager extends a class named BaseCommComponent (which extends flash.events.EventDispatcher), BaseCommComponent does not have any functions with the same name as those in CommManager.

So it turns out that the code was, in fact, using an external swf. Luckily, I had the matching fla file as well. Going into Publish Settings and checking the “Permit Debugging” box, along with recompiling seemed to fix it. Hope this helps anyone with a similar issue.
