Class DefaultPropertyAccessor

java.lang.Object

org.jasig.portlet.widget.service.DefaultPropertyAccessor

All Implemented Interfaces:

org.springframework.expression.PropertyAccessor

public class DefaultPropertyAccessor
extends Object
implements org.springframework.expression.PropertyAccessor

Author:

Josh Helmer, jhelmer@unicon.net Property accessor that tries to log an error and provide a default value if a property can not be found. Limitation: the accessor only gets access to the leaf property name. If you have a property like: user.login.id, this will only be able to print "${id}" In the future need to revisit to try and find a more flexible mechanism for handling without just throwing an exception.
