Chapter 2: ColdFusion Tags
Attributes
Usage
You must position
cfproperty
tags at the beginning of a component, above executable code and
function definitions.
If a component is not used as a web service, The
cfproperty
only provides metadata information
when the component is viewed using introspection; for example, by opening the CFC file directly
in the browser. It does not define variables or set values that you can then use in your component.
