If I use the 
URL:

http://localhost:8080/sysadmin/issue5?@error_message=foo

I 
see an error banner with the word foo.

If I 
use:
http://localhost:8080/sysadmin/index?@error_message=foo

or:

http://localhost:8080/sysadmin/?@error_message=foo

I 
see no error banner.

This is an issue for the goto item 
functionality. I claim that entering a non-existant issue number, not 
entering any value, or entering an invalid value (e.g. non-numeric) 
should result in the submitting page being redisplayed with an error 
message. If the page that was used to sumbit the erroneous issue 
is one of the last two pages, I can't get the error message 
shown.

Yep, this is in the "too hard" basket at the moment.

Finally I've been able to clean things up so this is fixable.
