JsonSerializationException: Self referencing loop

[izee]

My entities are double-sided reference
and I set IgnoreAttribute for back reference properties

        [System.Xml.Serialization.XmlIgnoreAttribute()]
        [System.Web.Script.Serialization.ScriptIgnoreAttribute()]

but i got Exception on serialization still

Newtonsoft.Json.JsonSerializationException: Self referencing loop

How do I?

Grid

<ext:Store ID="StoreExposicao" runat="server" AutoLoad="true" OnRefreshData="RefreshData1" RefreshAfterSaving="Auto" SerializationMode="Complex" >
            <Reader>

in class "Canario "

set the "Newtonsoft.Json.JsonIgnoreAttribute" for all properties if the type of property is "Exposicao"
