clearErrors
Purpose
Clear the list of errors on a domain class. This may be useful if a domain class contains errors because of
binding problems or validation problems. The errors may be corrected programatically. Validation may continue
to fail unless the errors are cleared.Examples
def b = new Book(title:"The Shining")
b.validate()
if(b.hasErrors()) { // clear the list of errors
b.clearErrors() // fix the validation issues
b.author = "Stephen King" // re-validate
b.validate()
}
