I couldn't figure out how to hide the security field and still have it default to the only valid security level. I set it to Required, and hidden, but when issues were added (by me), the security level was recorded as "None". It looks like I had 2 choices to resolve this: 1) unhide the field in order to get it to set the security level to the only valid choice 2) set the permission scheme so that the person entering the issue (me) cannot also set issue security I went with option 2.. Do you think that's a bug? i.e. just because I have issue security permissions doesn't mean it shouldn't still pick up the default security level when the field is hidden.
