I’ve heard nothing since I notified them. There has been some activity on the adobe bug forums, saying something about mode “direct” needing to be on, but that’s not the problem cause the app wouldn’t function in the first place. I also have <depthAndStencil>true</depthAndStencil> on as well, which may have something to do with it.. since it’s a sorting problem? I dunno. I can’t have that feature off.

We are using dev branch and for us this working without errors

var aid : uint
    var bid : uint
    try {
     aid = head.renderOrderId;
    } catch(e:*){
     aid = 0;
    } 

try{
     if(head && headB)
     {
      if (head.zIndex < headB.zIndex) {
       l = head;
       head = head.next;
      }
      else {
       l = headB;
       headB = headB.next;
      }
     }
     
    }catch(e:Error){
     return null;
    }

Hi, Has anyone found a fix or workaround for this error. On an Ipad 2 it goes wrong in several parts of the RenderableMergeSort class. I am using the new 3.6 SDK and the problem still exists on a Standard debug export. To make things worse it sometimes silently fails.

A little help on this would be great.

Just updated to Air 3.7 beta, this bug seems to have move up a few lines.

Line 56 it tells me about a null object, even though there isn’t any.

headB = slow.next;
   slow.next = null;

   // recurse
   head = mergeSortByDepth(head); // <--- ERROR, null object reference
   headB = mergeSortByDepth(headB);

I’m using Air 3.7 and getting the null object reference on the same line as 3dNewb.

Has anyone found a workaround for this yet?

Looks like this bug has been withdrawn because “cannotreproduce”.

I voted for it again. Maybe someone should just open a new one since this one has been withdrawn.

I am having this problem when trying to debug on an iPad Mini although it works when not debugging.

Version Data:
iPad Mini iOS: 6.1.3
Flash Builder: 4.7
AIR: 3.7
Away3D: commit a1167ad

But in my case I kann also see headB beeing NULL in the debugger. This happens on the second pass of the while loop. I don’t fully understand the code, but I think the intention of the loop definition is to break, when eitehr head or headB is null.

If I change Line 126 of RenderableMergeSort to this:


while (head && headB && head != null && headB != null) {

everything works fine.
