unfortunately it does not solve the problem. i tried to delete some other stuff i thought it could interference with the dittocall. but no chance.
still do not see a problem in my code. i think it is a bug.
i am using ditto 2.0.3, reflect 1.0.2 and modx 0.9.6.1
perhaps it helps if you see the link that reflect provides:
http://normal:8888/archiv.html?wp_month=11&wp_year=2007&wp_day=false&wp_start=0&wp_year=2007&wp_day=false&wp_start=0
EDIT: i see the problem. reflect builds XHTML valid urls. when disabled in the preferences of modx, everything works like a charm. so how can i use those nice valid urls with ditto and reflect?
