title: Releasing attributes from Model
body: <p>I am setting couple attributes to a model of Spring Model</p>
  
  <pre><code> myModel.setValue1
   myModel.setValue2  //Now setting this to request
   request.setAttribute("All_Values", myModel)
  </code></pre>
  
  <p>Making a service call under try catch block. If exception received, I want to release the <code>Value2</code> from my model and set only <code>Value1</code> to my request and make a service call again.</p>
  
  <pre><code> try{
   service call
   ...
   }catch(Exception e){
   myModel.release Value2 and have only Value1
   request.setAttribute("All_values", myModel) //This has only Value1
   service call again
   }
  </code></pre>
  
  <p>This is just an example if I could release couple of values if Exception received. <strong>I have many values in my model and not just two</strong>, so setting attributes individually to the request would be tedious.</p>
  
  <p>Could this be done?</p>
