title: Why are my changesets removed if I close a project?
body: <p>In Eclipse, I regularly close (rightclick on project -> close project) a subset of my projects for varying reasons.</p>
  
  <p>I noticed that if there are changes in the closed project that are assigned to a given changeset, the changes become "&lt; Unassigned >" when I open the project again.</p>
  
  <p>This is extremely frustrating since it basically leaves me the following two options:</p>
  
  <ul>
  <li>never ever close a project with changes assigned to a changeset</li>
  <li>re-assign all changes in the project to the desired changeset after having re-opened the project</li>
  </ul>
  
  <p>Why is this the case?</p>
  
  <p>Is there a way around this?</p>
