[rt-users] file: URL in Children field causes 'Can't call method "Id"' error in Display page

[Worsley, John]

Hi all,

My department is evaluating RT, and one of the things we're exploring involves linking to files on our network (supporting documents), so I've been trying to figure out the best way/place to put a file: URL in a ticket.  Attaching the files is sub-optimal because the files in question can change, and it gets too messy attaching multiple versions and expecting people to find the right one.  The only way I've found to have RT create a link from a URL is to put it in one of the Links fields (Parents, Children, etc.), but that's where my problem pops up.

I can use any of the Links fields except Children, but the Children field seems the most appropriate. The problem is, I put a file: URL in the Children field, and when I'm on the ModifyLinks page everything looks fine, but when I switch back to Display, the page draws okay until it gets to the Links section, where it displays a System Error in place of the Links section.  This does not occur with any of the other Links fields.  I have pasted the error text below.

We're using RT 3.4.1 because it was easy to install from Debian, which is what our dev box runs.  I realize the Links fields are intended to house RT tickets, not miscellaneous files, so in addition to help with this error, I welcome suggestions for better ways to accomplish making supporting files on our local network available in tickets.

Thanks!
