This has never been a problem before but now when I try to set the currentdataset of an object with an entitylist on any form it causes the bizobject to become null. It will create & work fine for oBisObj.Entity, but not for multi-row entitylists. When I try to save to the entity with a dataset, I also take errors that say I'm trying to insert invalid field types into certain columns.

this.oClient.Entity is populated but this.oClient.EntityList is null

       if (!IsPostBack)
        {
            this.oClient.GetClientsByClientUserUserID(gID);
            Session["dsClient"] = this.oClient.DataSet;            
        }
        else
        { 
            DataSet dsClient = (DataSet)Session["dsClient"];
            this.oClient.SetCurrentDataSet(dsClient);                     **** ERROR OCCURS HERE
        }
