[midgard-user] Fatal error: Call to a member function on a non-object

[Daniel Reichenbach]

Hy,

I'm using the following code to display a list of topics and their
articles. Now i also want to display the attachments available.
But it stops with th error message in the subject after the line
where i want to fetch the attachmenst using listattachments().

Any idea?

Daniel
