Hey Bob (or Tim),

I now have my code in both HookPreSaveEntity and HookPreSave, yet when I call the Parent BO's SaveEntity() this code does not get called. Where else do I need to call my code?

UPDATE: I needed the code in the HookPreSaveEntityList since this was a child business object

>There is a HookPreSaveEntity method as well which I guess gets called before SaveEntity. I would create another method to do what you want in a preSave and then call that method from both HookPreSave and HookPreSaveEntity.

>>>That seems about right. Make sure you also add to the child business objects the following in the HookConstructor method:
>>>
>>>

>>>protected override void HookConstructor()
>>>		{
>>>            this.AutoSaveOnParentSaved = true;
>>>            this.AutoCancelOnParentCancel = true;
>>>            this.AutoDeleteOnParentDeleted = true;
>>>            this.AutoEmptyOnParentAdded = true;
>>>            this.ForeignParentKeyField = "insert FK here";
>>>		}
>>>

>>>
>>>The only time the above code is used is when you use the RegisterChildBizObj method.

>>>Don't know the difference between SaveEntity and SaveDataSet as I always use SaveEntity.

mmSaveDataResult result = oPolicyHeader.SaveEntity();
