Override the IsChanged() method in ABusinessObject and add this code--let me know if this addresses the problem:

public override bool IsChanged()
{
	bool HasChanges = false;

	DataSet ds = this.GetCurrentDataSet();

	if (ds != null)
	{
		foreach (DataTable dt in ds.Tables)
		{
			HasChanges = this.IsChanged(dt);
			if (HasChanges)
			{
				break;
			}
		}
	}

	// Check if any child business objects have changes
	if (!HasChanges)
	{
		foreach (mmBusinessObject BizObj in this.RefBizObj)
		{
			HasChanges = BizObj.IsChanged();
			if (HasChanges)
			{
				break;
			}
		}
	}

	return HasChanges;
}

Best Regards,
