[phpOpenTracker-User] GraphViz / XML Question

Hi,

I am trying to do a new installation of phpOpenTracker. I also installed

graphviz-1.10 and
Image_Graphviz-1.0.1

but if I call the function to show clickpath, it only draws one box (so 
the graphics-engine at least is working). I have about 5000 entries in 
the database, so data is supposed to be there too ...

In order to find out whats missing I changed the result format to CSV.

Doing that I receive the error:

Fatal Error: Call to a member function on a non-object in 
/usr/share/pear/phpOpenTracker/API/plugins/clickpath_analysis.php on 
line 336.

Line 336 seems to be the line where a new object is created (which 
would make sense).

Any idea what I am doing wrong here?

The other question I have is:

I tried to change the result format to XML. This also does not work, 
because I cannot get XML_Tree installed. I did install XML parser, but 
there seem to be some undocumented requirements or modules I just did 
not install which are supposed to be there. Any ideas here?

The system I use is a complete installation of redhat 9 on the latest 
patchlevel.

THANKS FOR YOUR HELP IN ADVANCE!
Markus

PS: I forgot to mention, that beside these two things it seems to be a 
great software! Good work!
