Complex object types cannot be converted to simple values.

[Guest]

I am new to MX7, I test two lines of code as below:

<cfset url="#cgi.script_name#">
<cfoutput>#url#</cfoutput>
Then the error message shows:
---------------------------
Complex object types cannot be converted to simple values.
The expression has requested a variable or an intermediate expression result as a simple value, however, the result cannot be converted to a simple value. Simple values are strings, numbers, boolean values, and date/time values. Queries, arrays, and COM objects are examples of complex values. .....

-----------------------

Please help.

'URL' is a reserved variable in ColdFusion MX that contains any GET
passed variables, ie the query string.

You just need to use something else for your variable.

<cfset myURL = cgi.script_name>
<cfoutput>#myURL#</cfoutput>

Also note that there is no need to use the #'s in the cfset.

Thanks. I got it.
However, it worded in CF5.

Well, if you insist on naming your variable URL, then "scope" it properly in the output.

This works, but I don't recommend it:

<cfset url=cgi.script_name>
<cfoutput>#variables.url#</cfoutput>

Yes, in CF versions previous to MX you could override the 'URL' variable
structure with your own data.

Since MX, you can't do that anymore.
