The page where I found this happening the most was the following:
<body jwcid="@VisitationLayout" title="message:confirmation"
currentPage="Confirmation"
professional="ognl:isProfessional">
<form jwcid="visitorForm">
...
The first "@If" was the one that was missing from the hidden inputs
(although since it was the first one in the file, there's no reason to
assume that it was the only one to go missing).
What struck me as interesting is that the hidden storing the evaluated
Boolean expression was missing, but the form id must have been in the hidden
containing the form ids, as that threw a different exception when I tried
removing that.
The logs I was auditing are from a high-profile public-facing server, so it
is not terribly unlikely that this was the result of malicious actions on
the part of the user and not a bug (there were, in fact, indications that at
the time this was occurring at least one user was attempting to break in,
apparently unsuccessfully, thank goodness).
