Ok, I think i solved the riddle . H ad to remove the quotes from the function name (e.g. use ST_Point instead of "ST_Point"). This is due to the upCase=TURE parameter in addFunctions .
I don't see the error anymore. Now i'm facing another issue i believe is related with my adapter implementation. Thanks for the support!
