multiple selection select widget

[stdweird]

(this is with ood 3.1, didn't see anything relevant in teh 4.0 release notes)

i was trying to create a select widget that allows multiple selected values by adding in the html_options 'multiple: true'. the form itself then becomes a multi select field (as expected form the code), but something else still goes wrong.

from what i understand from rails, it also requires that the attribute handler/validation expects an array (some default value should be a [] instead of string); so i guess i also would need to modify some code somewhere.

can someone point me in the right place in the code where to start looking?

We don't support selecting multiple select options yet.
