#5 Warning: array_key_exists() Error

[Manfred Weber]

Hi,
I get following error:

"Warning: array_key_exists() [function.array-key-exists]:
The second argument should be either an array or an
object
in /usr/local/httpd/htdocs/gui/classes/class.XindiceDocu
mentCollection.php on line 46"

when trying to edit a collection.

How to solve that?
