title: How to share data (display same data) between two portlets in liferay?
body: <p>I have a scenario where user have two screens one for creating entity (like a new book) and the other for viewing that newly created entity.<br></p>
  
  <p>The user opens both screens and create a new entity and want to see that entity on the other screen.<br></p>
  
  <p>The entity is being saved into a list not database there fore,both screen are required to share same list of entity how this can be done ?</p>
  
  <p>What is the best (performance focused so that user don't see any lag) way to implement this in life-ray.</p>
  
  <p>**Note:**The existing system is extremely complex and is built using liferay and prime-faces mainly, This should be done without refreshing the viewing screen.
  This is only for one signed in user and has to be done using JSF(Prime-faces) </p>
