Method Detail

cascadeToAssociativeProperty

protected void cascadeToAssociativeProperty(org.springframework.validation.Errors errors, org.springframework.beans.BeanWrapper bean, GrailsDomainClassProperty persistentProperty)
Cascades validation onto an associative property maybe a one-to-many, one-to-one or many-to-one relationship.
Parameters:
errors - The Errors instnace
bean - The original bean
persistentProperty - The associative property

cascadeValidationToMany

Object collection = bean.getPropertyValue(propertyName);
protected void cascadeValidationToMany(org.springframework.validation.Errors errors, org.springframework.beans.BeanWrapper bean, GrailsDomainClassProperty persistentProperty, java.lang.String propertyName)
Cascades validation to a one-to-many type relationship. Normally a collection such as a List or Set each element in the association will also be validated.
Parameters:
errors - The Errors instance
bean - The original BeanWrapper
persistentProperty - An association whose isOneToMeny() method returns true
propertyName - The name of the property

cascadeValidationToOne

if (associatedObject == null) {
protected void cascadeValidationToOne(org.springframework.validation.Errors errors, org.springframework.beans.BeanWrapper bean, java.lang.Object associatedObject, GrailsDomainClassProperty persistentProperty, java.lang.String propertyName, java.lang.Object indexOrKey)
Cascades validation to a one-to-one or many-to-one property.
Parameters:
errors - The Errors instance
bean - The original BeanWrapper
associatedObject - The associated object's current value
persistentProperty - The GrailsDomainClassProperty instance
propertyName - The name of the property
indexOrKey

getAssociatedDomainClassFromApplication

protected GrailsDomainClass getAssociatedDomainClassFromApplication(java.lang.Object associatedObject)

getDomainClass

public GrailsDomainClass getDomainClass()
Parameters:
messageSource - The messageSource to set.

postValidate

}
protected void postValidate(java.lang.Object obj, org.springframework.validation.Errors errors)
Subclasses can overrite to provide custom handling of the errors object post validation.
Parameters:
obj - The object to validate
errors - The Errors object

setDomainClass

public void setDomainClass(GrailsDomainClass domainClass)
Parameters:
domainClass - The domainClass to set.
