I know how important it is to var scope your 'function local' variables
inside persistent cfc's. How do you handle calls to custom tags within
cfc's? does everything inside the custom tag need to be scoped?
The app I am working on uses a custom tag to make all database queries. this
tag was developed to prevent business logic from entering their queries.
Basically you perform any logic to dynamically determine variables you need
to pass to the query , create a struct containing the variables, and pass
that to the custom tag, along with the path to the cfm file that contains
the actual cfquery. The query is called using the parameters passed in the
struct. this makes the query available in the template you are working in.
I am already 'var' scoping the struct before passing it in. I am also var
scoping the query name used in the custom tag.
inside the tag, some stuff is attributes scoped, some stuff is caller
scoped, but there are many unscoped vars within the tag.
BTW, here is what the call inside the cfc looks like:
<cf_DBQ query="../returnedQuerynameHere"
path="#getCurrentTemplatePath()#">
this CFC is a utility CFC that will live in the application scope. will this
cause a problem when multiple users are calling it?
Thanks
Doug
