Object Cast error in Lucee not in CF

I’m switching from CF8 to Lucee.

I’ve been using a cfc to help with input sanitizing (portcullis from
riaforge). On the new Lucee server I’m seeing a lot (100’s per hour) of
errors"

“invalid call of the function filterTags
(C:\inetpub\wwwroot\CFC\Portcullis.cfc), first Argument (text) is of
invalid type, can’t cast Object type [Struct] to a value of type
[String];invalid call of the function filterTags
(C:\inetpub\wwwroot\CFC\Portcullis.cfc), first Argument (text) is of
invalid type, can’t cast Object type [Struct] to a value of type [String]”

I understand the message, but I don’t understand why I’m getting it. (and
why in Lucee but not CF)

all it does is pass some onRequestStart data

<cfset application.Portcullis.scan(url,“url”,cgi.remote_addr)>
<cfset application.Portcullis.scan(form,“form”,cgi.remote_addr)>
<cfset application.Portcullis.scan(cookie,“cookie”,cgi.remote_addr)>

and scan

just loops over the object passed

It fails at

I did redo the CFC because it uses the old style scoping (and rather lose
scoping) but that didn’t seem to help.

This error has no effect on users and doesn’t seem to be an issue at all
for site operation but it’s creating a lot of log files and I’d like to
eliminate it.

I’ve tried wrapping bits in a cftry/catch block but that’s doesn’t seem to
do anything. I’ve also tried dumping the #object# to a wddx packet and
saving to the log file but that hasn’t shown me anything out of the
ordinary.

I’m a bit stumped.

Any thoughts on what might be happening (or a replacement for portcullis)
are much appreciated.

filterTags() expects a string and returns a struct (I downloaded the code
and looked at the function).

The question I have is this: are the url, form and cookie scopes in Lucee
all “flat” in the sense that they only contain strings, and never a nested
struct? I don’t know. The error and your experience seems to indicate that
one of these contains a nested struct and filterTags() doesn’t know how to
deal with that.

http://www.codfusion.com/blog/page.cfm/projects/portcullis

Typically in your application.cfm or application.cfc page, you can load
Portcullis into a shared scope as a singleton.

<cfif isdefined(“application.Portcullis”) eq false>
<cfset application.Portcullis =
createObject(“component”,“com.fusionlink.Portcullis”).init()/>

As far as I know, that’s not sufficient to create a singleton, but rather
invites a race condition in the gap between the isDefined test and the
creation of the object.

Better would be:

<cfif not StructKeyExists( application, ‘Portcullis’ )>

<cfif not StructKeyExists( application, ‘Portcullis’ )>
<cfset application.Portcullis =
createObject(“component”,“com.fusionlink.Portcullis”).init() />

The singleton issue. I’m not really sure about the scope issue. As noted,
this worked without issue on ACF for years. Micha’s post addresses the
difference in usage, but didn’t seem to help. :confused:

Well I’m not 100% sure but we’re doing internal testing with a soft launch
of the new site so we’re generating most the traffic. Haven’t heard of any
issues. The CFC has no error handling in it’s original form.

My updated version (with modern scoping scheme) does, but I’ve gone back to
using the stock code until I can figure out what the problem is.On Tue, Sep 1, 2015 at 8:28 AM, Nando Breiter <@Nando_Breiter> wrote:

Just an FYI for the archive. Nando’s code above has a typo

<cflock name=“PortcullisLock” Timeout=“10” ThrownOnTimeout=“No”
Type=“Exclusive”>

sb

Thanks Nando,

Don’t think that’s the issue but I’ll change it as a best practice. (and
thanks for taking the time to research this…above & beyond!)>

So what happens if you ensure that only strings are passed into the
filterTag() function using a conditional to filter out any structs where it
is called? Does that eliminate the error?

So if for example “url” is a function argument containing a string, you
have to write “arguments.url”.

Are you referring to the singleton issue or my speculation that one of url,
form or cookie scopes may not be flat (contain only strings) in Lucee? If
one of those scopes somehow can contain a nested struct, then that would
explain the error you are getting, and perhaps the solution would be to
filter those out. I’m simply speculating …On Tue, Sep 1, 2015 at 3:07 PM, Jay B <@Jay_B> wrote:

I put in some struct filtering and logging

<cfif not isstruct(object[item])>

 do filterTags func.....

which produces





downloads



which would apply to the url index.cfm?content=downloads

it appears that -every- request is throwing the error (although as I
mentioned, it’s not affecting client side??)

I’m calling the function

<cfset application.Portcullis.scan(url,“vURL”,cgi.remote_addr)>

and the function is set up like so (I’ve added arguments scope which the
stock code doesn’t have)

I just don’t understand how object[item] can be a struct??? [item] should
be a string provided by the collection loop?
