Use of ParameterExists

The ParameterExists function has been deprecated since CF4, use IsDefined("var") instead

Type: deprecated
Severity: (3)

Incorrect example

<cfif ParameterExists(url.id)>
 do something
</cfif>

Resolution

<cfif IsDefined("url.id")>
 do something
</cfif>

Explanation

Deprecated functions may not be supported in future versions of ColdFusion, you should remove them so you can upgrade without worry. The IsDefined function is also faster than ParameterExists.
