Grails not binding Enumerations coming from forms

[cinar]

Hi,

Grails is not binding the Enumerations coming from the forms. Most likely I'm doing something wrong, any ideas?

Here are my domain objects:

class User {
   static hasMany = [userRoles: UserRole]
}

enum UserRole {
   ADMIN,
   GUEST
}

Here is the select box on the form:

<g:select name="userRoles" from="${UserRole.values()}"
                        value="${fieldValue(bean: userInstance, field: 'userRoles')}"
                        valueMessagePrefix="userRole"
                        size="5" multiple="true" />

The select box gets rendered correctly, however when I submit the form, the userRoles property of User domain object does not get the values.

Here is my controller:

def userInstance = User(params)

Thanks in advance for your help.

<g:select name="userRoles" from="${UserRole?.values()}"
                        value="${userInstance?.userRoles'}"
                        size="5" multiple="true" />

Rendering of enumeration is already working fine. The problem is that, when the form get submitted, the "userRoles" fields does not get correctly binded to the User.userRoles property.

I added a few log lines for debugging, and I am seeing that the params.userRoles is an array of Enumeration names. However after I do new User(params), all properties gets assigned except the userRoles property.

Does anyone have a working example with Enumerations?

Currently working for me:

<g:select id="sitio" name="sitio"
                            from="${Sitio.values()}"
                            optionKey="${{it.name()}}"
                            value="${usuario.sitio}"/>
