"and in this case only the setName(), getCount(), and setCount() methods will be added"

should be

setName has just been explicitly added

2nd paragraph

In the second paragraph: "and in this case, only the setName(), getCount(), and setCount() methods will be added"

The first method must be getName() instead of setName().

1st java code sample

The working java anonymous inner class example is missing a semi-colon in the interface (which I believe is supposed to be a Java interface, not a Groovy one):

interface Clickable {
void onClick()
}

It should use square brackets instead of squiggly brackets


interface Clickable {
void onClick();
}

1st paragraph/note - about "non-persistent domain classes"


The dialog/note on page 37 of Chapter 3: Persistence, just above the 'Data Validation' section, describes how one can achieve non-persistent domain classes.

It indicates:

"You may ask how to have non-persistent domain classes in your application, and the short answer is that you canít."

Technically, this is incorrect - you can have a non-persistent domain class in your application under .../grails-app/domain, by specifying:

static mapWith = "none"

... in the domain class that is intended to be non-persistent. ( this is nice also, because: it still supports constraints, you don't need to artificially separate non-persistent domain business logic off into ../src/groovy, or any other workarounds as suggested in that section.

More info:

http://jira.grails.org/browse/GRAILS-2515

... this feature is currently undocumented:
