Hello.
I'm working with a component that is stored in application scope. When a
duplicate() of the application scope is performed like in the code below, I
get an error that says the variable 'instance' is not defined when I try to
run request.app.objSQLServerDAOFactory.dump(). Calling
application.objSQLServerDAOFactory.dump() works fine.
lock
application.objSQLServerDAOFactory =
application.objDAOFactory.init(application.objDAOFactory.SQLServer);
request.app = duplicate(application);
/lock
However, if duplicate is not used as in request.app = application; then
running request.app.objSQLServerDAOFactory.dump() runs as expected.
Can someone explain to me why this is? I'm know duplicate() does a deep copy
and assigning the value directly just gives you a reference to the original
variable.
SQLServerDAOFactory Code
--------------------------------------------
<cfcomponent displayname="SQLServerDAOFactory" hint="Creates SQL Server DAO
components">
<cfset init()>
<cffunction name="init" access="package" output="false"
returntype="void">
<cfset instance = structnew()>
<cfset instance.datasource = "">
</cffunction>
<cffunction name="getPageDAO" access="public" output="false"
returntype="PageDAO">
<cfset obj = createobject("component", "PageDAO")>
<cfset obj.setDatasource(instance.datasource)>
<cfreturn obj>
</cffunction>
<cffunction name="setDatasource" access="package" output="false"
returntype="void">
<cfargument name="datasource" type="string" required="yes">
<cfset instance.datasource = arguments.datasource>
</cffunction>
<cffunction name="dump" access="public" output="true"
returntype="void">
<cfdump var="#instance#">
</cffunction>
</cfcomponent>
Thanks,
Phillip
