Invalid BitmapData Error #2015

programming flash
1

I’m getting an Invalid BitmapData Error #2015 at flash.display::BitmapData$iinit() that points to the line of code below where a BitmapData object is created. I am using this function to create only a few hundred Item objects, each of which is only 166 px by 96 px in size so I don’t believe that the problem has to do with running out of memory. I also used system.totalMemory to trace memory consumption but it showed that only a few tens of megabytes were used when the error occurred. I have tried setting the BitmapData and Bitmap objects to null because that was a solution I found on another site. That didn’t work. I tried dispose(). The error occurs intermittently, sometimes after running my app a few times and sometimes when I first load it. I am not refreshing my browser over and over in order to run the app. I cannot figure out the exact sequence of events that leads to this error. In earlier versions of my app, I was able to successfully use the exact same function (minus the lines where the BitmapData and Bitmap objects are set to null). I am not an expert at Actionscript, so perhaps I’m doing something wrong. Please help me out. Thanks.

public function cloneItem(item:Item):Item {
var itemClone:Item = new Item(item.ID, item.name, item.bpCost, item.bcCost, item.quantity);
