I am having problem when I read oracle char data type on edit
form(after saving the form and go to edit page again, all the radio
buttons are unchecked). text_field works fine for char data type. Is
there any special way that I need to use for reading oracle char data
The CHAR data type in Oracle specifies a fixed-length character string.
inserting a value that is shorter than the column length, Oracle will
the value with blanks. If the length of the column is 2 and you insert
the string "1 " will be stored, so the radio button generated by “<%=
radio_button (‘attending_ip’, :problem_1_status, ‘1’) %>” won’t be
because ‘1’ does not equal to '1 '.
