If you create a new module with imBuilding, than it's not possible to see the details from an item in the module ACP.

Step to reproduce:

- create a new module and install this module
- enter some items into your new module
- click in the module ACP on an item to see the details about it
- the page will not open, you can not see the details

If you change the URL manually, than works.

from:
modules/modulename/admin/item.php?item_id=1
to:
modules/modulename/admin/item.php?op=view&item_id=1
