-/**
- * This is a command to help generating navigation urls in the view. I got
tired of all
- * the URL handling velocity code. Some of the effects from this is virtually
impossible to
- * code in velocity.
- * <p/>
- * TODO This should be a multiResult resulthandler, but right now this just a
waiting searchCommand.
- * Usually there will be no real waiting since the calls on the results occur
from velocity.
- * <p/>
- * As a bonus from using this, you don't need to data-model the commands that
only are
- * there for navigation.
