This method is called when this configurable component needs to be reconfigured.

Specified by:

newProperties in interface Configurable

Overrides:

newProperties in class Grammar

Parameters:

ps - a property sheet holding the new data

Throws:

PropertyException - if there is a problem with the properties.
