I have seen your error (as requested), and it's not pretty. However, I can offer you two comments:

1. You should format it better to make it clearer. For the multi-line trackback, you'll want to format it using blockquotes. select the text, then click on the IOIO icon (or press Ctrl K).
   

   

   « click that after selecting your pasted code!!

2. Your problem seems to be in your ip_list_read function in admin_view.py line 548. Perhaps index-1 is larger than the actual size of the list returned by object_persistence(...)?

Of course, this is all guesswork as I don't know what the rest of the function look like, or what you're trying to achieve.

Update

Somewhere within that pile of code you have something that looks like

if chk_exist_obj: 
    chk_exist_obj = chk_exist_obj[0] 
    ip_type = chk_exist_obj.ip_type 
    arranged_list = arrange_ips(chk_exist_obj) 
    print arranged_list 

Your arrange_ips() function is the one that's causing the problem. What exactly does it do? Based on the statement chk_exist_obj = chk_exist_obj[0], we see that chk_exist_obj is now a single list item. What are you trying to arrange?

From the trackback printout, arrange_ips() calls ip_list_read() which fails on line 548 as it tries to access a list entry that does not exist.
