Disc image alias don't work in dock

Question

I recently 'upgraded' to mountain lion and since then my dock shortcuts no longer work;
I keep all of my personal files inside an encrypted sparse image then I have alias files for that drive and some of the folders within it stored on the local drive which I would then have in finder.
This used to work perfectly well and if the volume wasn't mounted it would prompt me to do so.
Now; it prompts me if the drive isn't mounted but then the links don't open their target folders, they work fine if I open the alias from within finder, shortcuts to physical drives and folders on physical drives still work fine when in the dock. 
nb; the folders within the sparse image can still be added to the dock as a stack but that doesn't solve the issue.
Anyone have any ideas?
Thanks.

Answer 1

Thank you so much for the tip.  It worked, in a sense.  But I have several individual files I'd like to have aliases for.  If I drag each one to the dock, my dock would be cluttered with these aliases.  Prior to mountain lion, I was able to have a folder of aliases on my dock, in list form or stack form.  I can still do that with any files not in a sparsebundle.  But the files in my sparsebundle won't work in that alias folder.  They only work as you suggested, individually dragging each one to the dock.
Is there any way to consolidate these aliases into one folder on the dock?
Again, thank you very much for your time and attention.
