ClassCastException

[vernade]

My company develops websites, most of them running on ColdFusion 6.1. Now we
are trying to migrate from ColdFusion 6.1 to ColdFusion 7.0 (for some
websites).

I was able to find and resolve most incompatibilities, save this next one: I'm
getting this Java stack trace from a ClassCastException which I cannot
interpret. I'm using my own Java classes in the background, but the stack trace
does not indicate an error in one of my classes. Furthermore, I cannot
determine a line in my .cfm files.

Can you give me a hint where to search for the error?


--------------- ColdFusion Error Message and Java Stack Trace ---------------
Error casting an object of type to an incompatible type. This usually
indicates a programming error in Java, although it could also mean you have
tried to use a foreign object in a different way than it was designed.

Please try the following:

* Check the ColdFusion documentation to verify that you are using the
correct syntax.
* Search the Knowledge Base to find a solution to your problem.

So, I was able to isolate a portion of the code which leads to the problem
above... obviously a complation error, although, I wonder why ColdFusion prints
the stack trace instead of a standard error message.


<cfif (hasPermission("editor,ptranslator", 0, getCurrentLocale()) and
jnodetype.getConfig().useHistory() and not
jnodetype.getConfig().isAutoPublish())
or (hasPermission("admin") and jnodetype.getConfig().useLocale() and
getLocales().RecordCount gt 1)>
<cfset showpublishtranslatebox = "yes">
</cfif>

Also, this code produces the error message above:
<cfoutput><input type="hidden" name="instance" value="#instance#"></cfoutput>

It seems to me, that this is a ColdFusion Bug.

Has anyone other than me encountered this problem?
