Missing Else Segment of Ternary IF threw unrelated error location

To summarize my site in quick detail.

It uses application.cfc's onRequest and includes my site template.

I was adding something to a page today involving a ternary if and wrote this

#(CurrentID eq SCANFORID ? " selected")#

Saved the file and left for a bit. This is just on my testing server so no harm.

I came back to an error telling me [[Invalid conditional operator}} occurring in the template handler file on the line that includes the file.

Obviously it was easy to fix, find the ternary in my file and change it to

#(CurrentID eq SCANFORID ? " selected" : "")#
