CF9 ORM anf Flex bidirectional relation

Question

Hello,
I'm working with two object which are in one-to-many relation "installazioni" (one) and "interventi"(many), which I have to show in three different way.
In the first view I show the complete list of "interventi" in another view I show the complete list of "installazioni" and in the last view I show one "installazioni" and the related "interventi".
The problem is to show the "interventi" cause some of the property I have to show are related to its "installazioni" master record.
I defined the to object in this way :
*** Installazioni ***
component persistent="true" alias="Installazioni" 
    property name="IDInstallazione" column="IDInstallazione" type="numeric" ormtype="int" fieldtype="id" default="0" generator="identity" unsavedvalue="0";
    property name="SerNo" column="SerNo" type="string" ormtype="string";
    property name="IDArticolo" column="IDArticolo" type="numeric" ormtype="int";
    property name="ScadGar" column="ScadGar" type="date" ormtype="timestamp";
    property name="Versione" column="Versione" type="string" ormtype="string";
    property name="ROM" column="ROM" type="string" ormtype="string";
    property name="PrinterSN" column="PrinterSN" type="string" ormtype="string";
    *** Interventi relation ***
    property name="InterventiInstallazione" type="array" fieldType="one-to-many" cfc="Interventi" fkcolumn="IDInstallazione" remotingfetch="true" lazy="false" inverse="true";
*** Interventi ***
component persistent="true" alias="Interventi"
    /* properties */
    property name="IDIntervento" column="IDIntervento" type="numeric" ormtype="int" fieldtype="id" ;
    property name="UltimoCT" column="UltimoCT" type="numeric" ormtype="double" ;
    property name="UltimoCHtot" column="UltimoCHtot" type="numeric" ormtype="double" ;
    property name="Soluzione" column="Soluzione" type="string" ormtype="string" ;
    property name="DurataIntervento" column="DurataIntervento" type="numeric" ormtype="double" ;
    property name="PresaVisione" column="PresaVisione" type="numeric" ormtype="boolean" ;
    property name="Cicli" column="Cicli" type="numeric" ormtype="int" ;
    property name="Ore" column="Ore" type="numeric" ormtype="int" ;
    *** Installazioni inverse relation  ***
    property name="Installazione" type="Installazioni" fieldtype="many-to-one" cfc="Installazioni" fkcolumn="IDInstallazione" remotingfetch="true" lazy="false";            
For ex. I need to show the SerNo property in the list of "interventi" referring to the "installazione" property.
In standard HTML everything works and I can show the "SerNo" property (Interventi.Installazione.SerNo).
In Flex the when I try to retrieve the "installazione" valueObject I can read correctly the "interventiInstallazione" array but I can't access the "Installazione" property of each "InterventiInstallazione" element cause it is null.
Following the two VO declaration :
*** Installazioni ***
package valueObjects {
    import mx.collections.ArrayCollection;
    [RemoteClass(alias="CBCWeb.cfcs.Installazioni")]
    [Bindable]
    public class Installazioni {
        public var IDInstallazione:Number = 0;
        public var SerNo:String = "";
        public var IDArticolo:int = 0;
        public var ScadGar:Date = null;
        public var Versione:String = "";
        public var ROM:String = "";
        public var PrinterSN:String = "";
        public var InterventiInstallazione:Array;
*** Interventi
package valueObjects {
    [RemoteClass(alias="CBCWeb.cfcs.Interventi")]
    [Bindable]
    public class Interventi {
        public var IDIntervento:Number = 0;
        public var UltimoCT:Number = 0;
        public var UltimoCHtot:Number = 0;
        public var Soluzione:String = "";
        public var DurataIntervento:Number = 0;
        public var PresaVisione:Number = 0;
        public var Cicli:Number = 0;
        public var Ore:Number = 0;
        public var Installazione:Installazioni;
Following the result of reading one "installazione" :
Where I made the mistake ?
How can I retrieve the inversed relational property to show its values for the object sleected ?
Thanks in advance,
Davide

I struggled with this for hours a few weeks back.  Add the attribute remotingfetch="true" to your relationship like this:
<cfproperty name="Tenants"
                    fieldtype="one-to-many"
                    singularname="Tenant"
                    cfc="Tenants"
                    mappedby="Tenants"
                    fkcolumn="TenantID"
                    remotingfetch="true"
                    lazy="false"
                    type="array"
                                <!--- can be array or struct ---> 
                    <!---structkeytype="int" structkeycolumn="ID"--->
                    />
Hope this helps!
