Actually, I work almost exclusively with the iRule editor and can't imagine what it would be like to
not have it available. Occasionally, I'll resort to vi-ing the bigip.conf file to make global name changes (renaming an iRule and its references, for instance). However, the iRule editor didn't catch this error. Before I made that assertion, I reintroduced the error and clicked on the Check Syntax button. I got the popup dialog box that claimed "The text is a valid irule.". Previously, I got a successful save status when I saved it, too.
