org.apache.velocity.app.event.implement.ReportInvalidReferences
Use this event handler to flag invalid references. Since this is intended to be used for a specific request, this should be used as a local event handler attached to a specific context instead of being globally defined in the Velocity properties file.
Note that InvalidReferenceHandler can be used in two modes. If the Velocity properties file contains the following:
```
 eventhandler.invalidreference.exception = true 
```
then the event handler will throw a ParseErrorRuntimeException upon hitting the first invalid reference. This stops processing and is passed through to the application code. The ParseErrorRuntimeException contain information about the template name, line number, column number, and invalid reference.
If this configuration setting is false or omitted then the page will be processed as normal, but all invalid references will be collected in a List of InvalidReferenceInfo objects.
This feature should be regarded as experimental. @author Will Glass-Husain @version $Id: ReportInvalidReferences.java 470265 2006-11-02 07:45:02Z wglass $
