Question

Does anyone know about this error I get when I try to insert a foreign key value in my entry entity using ColdFusion 9 Hibernate integration?

java.lang.ClassCastException: java.lang.String cannot be cast to coldfusion.cfc.CFCBeanProxy

Root cause :org.hibernate.HibernateException: java.lang.ClassCastException: java.lang.String cannot be cast to coldfusion.cfc.CFCBeanProxy

Below is the code for my entity object and then for my user object..

Is there anything wrong with this?

entry.cfc

/**
* Entries Object
*/
component output="false" persistent="true"{
    property name="entry_id" fieldType="id" generator="uuid";
    property name="entryBody" ormType="text";
    property name="title" notnull="true" type="string";
    property name="time" fieldtype="timestamp";
    property name="isCompleted" ormType="boolean" dbdefault="0" default="false";
    property name="userID" fieldtype="many-to-one" fkcolumn="userID" cfc="user";

    Entry function init() output=false{
        return this;
    }
}

user.cfc

/**
* Users Object
*/
component output="false" persistent="true"{
    property name="userID" fieldType="id" generator="uuid";
    property name="firstName" notnull="true" type="string";
    property name="lastName" notnull="true" type="string";
    property name="password" notnull="true" type="string";
    property name="userType" notnull="true" type="string";
    //property name="entry" fieldtype="one-to-many" type="array" fkcolumn="userID" cfc="entry";

    User function init() output=false{
        return this;
    }
}

Answer 1

property name="user" type="User" fieldtype="many-to-one" fkcolumn="userID" cfc="User";

Because the property should be type User, not the ID? In CF-ORM/Hibernate, there’s no way to just set FK. You must…

entry = EntityNew("Entry");
user = EntityLoadByPK("user",1);
entry.setUser(user);
