Runtime exception errors

If ColdFusion encounters a runtime exception, it does the action for the first matching condition in the following table:

Condition	Action
The code with the error is inside a `cftry` tag and the exception type is specified in a `cfcatch` tag.	Executes the code in the `cfcatch` tag. If the `cftry` block does not have a `cfcatch` tag for this error, tests for an appropriate `cferror` handler or site-wide error handler.
A `cferror` tag specifies an exception error handler for the exception type.	Uses the error page specified by the `cferror` tag.
The Administrator Settings Site-wide Error Handler field specifies an error handler page.	Uses the custom error page specified by the Administrator setting.
A `cferror` tag specifies a Request error handler.	Uses the error page specified by the `cferror` tag.
The default case.	Uses the standard error message format

For example, if an exception occurs in CFML code that is not in a cftry block, but a cferror tag specifies a page to handle this error type, ColdFusion uses the specified error page.
