title: Using AddLookupMethod
body: <p>I have a lookup created by code filled with a query on ProjTable. I want to add a field to this lookup that is a display method on ProjTable (displayCustName) that retrieves the name from CustTable for each customer related to the relative contract of the lookup.</p>
  
  <p>I found that I could do this with 'AddLookupMethod', it adds the field to the lookup but empty. I don't know how to use it properly, any help?</p>
  
  <p>Thank you.</p>
