title: Lotus Notes: how can i check if saved document has been modified
body: <p>In lotus notes 6.5 , how can i check if a document fields are different than before ?</p>
  
  <p>Now i have put some code in the Queryopen that populate a field "<em>changes</em>" with some source document values and in the querysave i check if values that i  had save during queryopen are different from the fields in the source document. If they change i have to update some other documents, in other case i don't have to update anything.</p>
  
  <p><strong>Is there other simplier solution ?</strong></p>
