Decision cube

Hai,

is there anyone using the decision cube components from D5 and know a link
where I can find some additional information about how to use of these
components, or a faq about some known problems (for example skipping data
when a Null-field is encounterd) , I've tried to find info myself, but it
looks that I'm the only one trying to make these components work, . If
anyone knows an better alternative than these components, please let me know
also

Can you please cc to Richard<REMOVESPAMFILTER>@defacto.nl

Tanx.
