File Modified Error

After months and months and MONTHS of trying to find a solution to the dreaded ' file has been modified by SHAREPOINT\system ..' when using an event receiver in the ItemAdded event, im happy to announce that I have finally got rid of it!!The way in which i did, which initially i thought was impossible or didnt work, was by doing it all in the ItemAdding event and using the after properties.

Getting a BCS Column related field name

Whilst some people might go through the process of using an XML parsing to get the RelatedField static name for a BCS Column(typically to set it e.g.) :

SPField tagField = oItem.Fields["Account"];                             

XmlDocument xml = new XmlDocument();

xml.LoadXml(tagField.SchemaXml);

String sEntityName2 = xml.FirstChild.Attributes["RelatedFieldWssStaticName"].Value;

I think a more quicker and efficient way is to do the following :

tagField.RelatedField.ToString();
