Tag and function examples

This section provides remedies for some of the compatibility issues listed in Chapter 3, “Tag and

Function Changes.”

Using cfregistry in ColdFusion MX

The

cfregistry tag is deprecated for UNIX and Linux platforms. Therefore, you must remove it

on UNIX to avoid compatibility problems when migrating to a later version of ColdFusion MX.

As an alternative, you can store variables in the following scopes:

• Client

• Text file

• Encoded text file

• Database

• LDAP server

In Windows, you can continue to store client variables in the registry as in ColdFusion 5.

However, you should not use

cfregistry to read ColdFusion settings from the registry, such as

the mail root and information about Verity collections and scheduled tasks, because much of this

information is no longer stored in the registry, or it is in a different location in the registry. The

ColdFusion settings that are stored in the registry are subject to change. Therefore, you should

not rely on registry keys that ColdFusion creates to store its system settings.

Using ListSort in ColdFusion MX

When sorting with

textnocase in a descending order, ColdFusion 5 and ColdFusion MX

return the results in a different order. However, both are correct because in a

textnocase sort,

“apple” is equal to “APPLE”.

In ColdFusion MX, a descending

textnocase sort returns the elements in the exact reverse order

as in an ascending

textnocase sort. This is different than in ColdFusion 5.

The following code produces different results in ColdFusion MX than in ColdFusion 5:

This code produces the following results for ascending and descending sort operations in

ColdFusion 5 and ColdFusion MX:

For more information, see the

ListSort function in CFML Reference.
