I am trying to populate a multiple select box using javascript, but am having problems with the name. When I change the name to "codes[]" I can''t get the javascript to find the form element, but without the [] on the end, rails wont read all of the selected values. Here is an example of the javascript working, but when you submit the array is not passed across for the codes.

...l) a <- as.multipol(matrix(1:10, nrow = 2)) a*a # gives correct results So I tried to see what is the str of a to understand if I did something wrong (that destroyed the structure of my data). str(a) Error in `[.multipol`(object, seq_len(ile)) : incorrect number of dimensions Calls: str ... formObj -> paste -> format.fun -> format -> [ -> [.multipol And right now I am at a stalemate. I can not find out why my multiplication failed If I can not find the structure of a. What should i do now? Regards Alex
