By default In-Portal looks for an ID of DBItem that is accessed from
template in the url. When item ID is missing, but it's data needs to be
displayed on a template, then "no_permission" template is shown.
As a part of customization process developer sometimes needs to load DBItem
from database using not it's ID, but a combination of fields.
All works fine until nothing is loaded by a field combination.
In this case <inp2:prefix_Field name="IDField"/> tag returns "Array" field
instead of "" as usual for unsuccessfully loaded DBItems.
Task:
Ready for testing.
