I have a schema published as SOAP header. Some of the fields are promoted. I
 have to extract those fields and populate another object before calling an 
external dll. The problem happens when I assign these fields to the fields i
n the object. 

For example, "sessionMemento" is the object, 

sessionMemento = new EReferrals.ERUI.UIServices.SessionMemento();
sessionMemento.UserId = myNamespace.PropertySchema.UserId;

when I do this, the XLang compiler complains that 

cannot implicitly convert type 'myNamespace.PropertySchema.UserId' to 'Syste
m.Int64'

when the UserId in the exposed schema is actually a Int64. How could this be
 resolved. Thanks in advance.
