Group: StrataFrame Users Posts: 430, Visits: 507	I have the following code in my Parent BusinessObject Vlaidation to ensure that at least one Child is entered.... works fine from my main Parent/Child data entry form ChildBO myChildBO = (ChildBO)this.ChildBusinessObjects[0]; if (myChildBO.Count <= 0) { this.AddBrokenRule(this.ITR_CUSREF, "There must be at least one Detail Line"); } Now , on a different form, where I am updating just one field from the Parent Business object, the MyParent.Save() gives an index error, probably because the Child BO is not instantiated. On this partcular form , the Child BI is not used at all. How do I 'Instantiate' and populate the child Business Object in Code , so that the error does not happen (I have tried the folloiwng code, but not quite sure what it does...got from another thread) BusinessParentRelationship myRel = new BusinessParentRelationship(); myRel.ForeignKeyField = new string[] { "IDE_ITRPK" }; myRel.ParentPrimaryKeyField = new string[] {"ITR_PK"}; myRel.ParentBusinessObjectType = "ITR"; ChildBO1.ParentRelationship = myRel; ChildBO1.IdeFillByItrpk(itrBO1.ITR_PK);
