ColdFusion isDefined getting undefined error

Question

I have:

<cfif not isDefined(activity)>
    <cfset activity="">
</cfif>

And I get the error :: "Variable ACTIVITY undefined."

AND?

Oh, and the error is with isDefined

, not with cfset

.

Try:

<cfif structKeyExists(VARIABLES, 'Activity')>
<cfset Activity = "Something" />
</cfif>

We can use like this

<cfif not structKeyExists(variables,"Activity")>
    <cfset Activity = "">
</cfif>
