When having a custom boolean field for my issues, I was not able to set it to true since the hidden input value was used when updating the values instead of the checkbox value. Changing the order of the hidden input and the checkbox solved this issue. Just replace in /usr/share/redmine/app/helpers/custom_fields_helper.rb around line 47:

hidden_field_tag(field_name, '0') + check_box_tag(field_name, '1', custom_value.true?, :id => field_id)

by

check_box_tag(field_name, '1', custom_value.true?, :id => field_id) + hidden_field_tag(field_name, '0')
