Hello

I have problems with rendering XML.
In my web app I have 2 classes:

Code:
class Vprasanje {

    String naziv;
    String besedilo;
    Boolean flag
    Date dateCreated;
    Date lastUpdated;
    static hasMany = [operandi: Operand]

    static constraints = {
        flag(blank: false, nullable: false)
        naziv(blank: false, nullable: false)
        besedilo(blank: false, nullable: false)
    }
}
and

Code:
class Operand {

    String ukaz
    Boolean tip
    static belongsTo = [vprasanje:Vprasanje]

    static constraints = {
        ukaz(nullable: false, blank: false)
        tip(nullable: false, blank: false)
    }
}
Then in VprasanjeController in list I have this:
Code:
def listXML = {
        render Vprasanje.findAllByFlag(true) as XML
}
and in XML response I get XML like this:

Code:
<list>
−
<vprasanje id="1">
<besedilo>To je moje novo vprasanje.</besedilo>
<dateCreated>2010-09-09 14:42:56.775 CEST</dateCreated>
<flag>true</flag>
<lastUpdated>2010-09-09 14:42:56.775 CEST</lastUpdated>
<naziv>Vprasanje 1 </naziv>
−
<operandi>
<operand id="1"/>
<operand id="2"/>
</operandi>
</vprasanje>
</list>
Now I would like to have full operand review in XML response. How to make this ? Any suggestions ?

Thanks, Simon
