(Quick Reference)



Configure the bindability of a property.


salary bindable: false
firstName size: 5..15, bindable: true
department bindable: true


Set to false to indicate that a property is not to be automatically assigned a value during data binding.

package com.demo

class Employee { String firstName String department BigDecimal salary

static constraints = { department bindable: false salary bindable: false } }

import com.demo.Employee

def employee = new Employee() employee.firstName = 'Bill' employee.department = 'Percussion' employee.salary = 42.0

// department and salary will NOT be bound because they are configured as non-bindable in the Employee.constraints closure employee.properties = [firstName: 'William', department: 'Retired', salary: 99.99]

assert 'William' == employee.firstName assert 'Percussion' == employee.department assert 42.0 == employee.salary

Statically typed instance properties are bindable by default. Properties which are not bindable by default are those related to transient fields, dynamically typed properties and static properties.

See the data binding section for more details on data binding.

The bindable constraint must be assigned a literal boolean value. Dynamic expressions are not valid values for the bindable constraint. The value must be the literal true or false.

The bindable constraint must be applied in the constraints closure which is defined in the relevant class. This means that bindable may not be used as a shared constraint.
