Other changes in ColdFusion MX 7 25
Forms and validation enhancements
If your application uses the
cfform tag or server validation, ensure that you review the
enhancement discussions in the Release Notes. In particular, rich forms (using Macromedia
Flash) and skinnable forms (using XML) provide major enhancements to form display and
processing.
Improvements to the cfchart tag
ColdFusion MX 7 includes the following enhancements to the
cfchart tag:
• An updated charting engine provides improved output.
• Use the new title attribute in the cfchart tag to specify the title of the chart.
• You can now use dates on the y-axis of a chart.
• The cfchart tag lets you specify the style of the chart in either an XML file or string.
Query of Queries
Changes to the Query of Queries include the following:
• More lenient type comparisons. Query of queries now makes the best effort to compare
expressions of different types by doing implicit casts.
• Support for the CAST (expression AS casttype) function.
• Support for the varchar concatenation operator ||.
• Support for SQL and ODBC style dates inside a query of queries.
• Size is no longer a reserved word when you create a query of queries, so you can create a query
of queries using the
cfdirectory tag with a column named Size.
• Query metadata support. Lets you specify data type metadata for query columns that you
create using the
QueryNew and QueryAddColumn functions. The following parameters have
been added to these functions:
■ QueryAddColumn datatype parameter
■ QueryNew columnTypeList parameter
Verity upgrade and enhancements
The ColdFusion MX Verity implementation has been completely rewritten to use Verity 5.5 and
its all-Java interface, which has many implications, including the following:
• Verity 5.5 uses a client-server paradigm. ColdFusion MX no longer manages collections
directly and all collections are managed by the Verity search server.
• There is no longer the concept of external and internal collections.
• Verity pages in the ColdFusion MX Administrator have changed.
• Because ColdFusion uses a pure Java interface to Verity, native libraries are no longer required.
