title: get value of computed when composed field value in xpages
body: <p>i have a computed when composed field in lotus notes (with formula @unique). I'm trying to retrieve this value and assigning it to a viewScope (in "after page load" event of the page in the following way </p>
  
  <pre><code>viewScope.unid=currentDocument.getItemValueString("unid"). 
  </code></pre>
  
  <p>My problem is when i open the page for first time it is working correctly (assigns the value to viewScope). But when i refresh the page viewScope is blank. i have also tried retrieving the computed when composed value to an xpage with no luck. am i doing anything wrong here?</p>
  
  <p>there is one catch here, i'm opening the document from lotus notes view (not from any container controls //?opendocument) and this documents opens using xpage</p>
