[color=blue]Coding in Grails, thinking in Java
August 12th, 2009

By default we create a domain class and generate controller and view for that domain class. Run the app and everything works fine.

Create another controller and access that domain object will encounter java.lang.NullPointerException due to domain object is null.

Simply, because I forgot to import that domain class into this controller.

This reminds me if I don't know how to do things in Grails, think, how I do it in Java.[/color]


正如所言，Grails编码，用Java思考，面向对象思想是最重要的。[/size]
