This just saved me time. I, like you, tried def setIsbn(i){ ... } to find nothing doing. Thanks! This just saved me time. I, like you, tried def setIsbn(i){ … } to find nothing doing.

on a credential domain class I wanting to guard against a password field being set to a non-hashed value… So my initial thinking was to create:

String password
void setPassword(String pw) {
password = getHash(pw,salt)
}

but if the hashed password was retrieved from the database wouldn’t it end up going through another cycle of hashing?

THAT's really usefull since I need to format the date from String to java.util.date (i am not using g:datepicker, but using my own javascript date picker). thank you for sharing your knowledge... oh great. i just know that we can override the setter in GORM.

One way you can make sure you get the correct method signature is to run javap on a compiled groovy class (before you override the method, of course): groovyc Book.groovy javap Book Compiled from "Book.groovy" public class Book extends java.lang.Object implements groovy.lang.GroovyObject{ ... public void setIsbn(java.lang.String); .... } You can then copy that method signature directly into your code to and override it to your hearts content.

Great post – I’ve struggled with the same thing in the past. One way you can make sure you get the correct method signature is to run javap on a compiled groovy class (before you override the method, of course):

groovyc Book.groovy
javap Book
Compiled from “Book.groovy”

}

You can then copy that method signature directly into your code to and override it to your hearts content.
