gorm entity with multiple constrains

Question

class Book {

String name
String author       
 static constraints = { name(nullable:true) 
}
}

The above seems to work, however when i put in constraints for multiple fields the server does not start up

class Book {

String name
String author       
 static constraints = { name(nullable:true) author(nullabe:false)
}
}

With the above code ... I get the below exception

Caused by: groovy.lang.MissingMethodException: No signature of method: org.codehaus.groovy.grails.validation.ConstrainedPrope rty.call() is applicable for argument types: (org.codehaus.groovy.grails.validation.ConstrainedProperty) values: [org.codehau s.groovy.grails.validation.ConstrainedProperty@3343e5[class com.nthdimenzion.domain.Book,author,class java.lang.String,{nulla ble=org.codehaus.groovy.grails.validation.NullableConstraint@1aea6e2[false]}]] Possible solutions: wait(), any(), wait(long), each(groovy.lang.Closure), any(groovy.lang.Closure), isUrl() at com.nthdimenzion.domain.Book$_clinit_closure1.doCall(Book.groovy:16) at com.nthdimenzion.domain.Book$_clinit_closure1.doCall(Book.groovy) ... 23 more

Any ideas ?

Its because you have it on the same line...

try

 static constraints = { 
    name(nullable:true) 
    author(nullabe:false)
 }

EDIT:

You can alos separate the entries with ; then you can have it all on one line if that is what you want. (however i think the majority of us don't use oneliners...)
