Hi Marc,

thanks for your response. Using IRRE MM with Extbase itself is not the 
problem. Using it as a relation to itself (i.e. Post <-M:N-> Post to 
show related posts) does not work out with IRRE/Extbase.

I have not been able to find a solution in the list for that, but maybe 
I looked at the wrong place.

Any clues are welcomed ;-)

Thanks,

Henjo
