title: Spring Roo: how can I code a customized search page based on several backing entities?
body: <p>As we know, Roo will create a list pages for every entity. Suppose I have 3 domain classes - Company, Dept. and Employee, I want to display the detail info in a customized list page, which will contain the fields from all of the 3 classes, how can I code?
  I used the 'web mvc controller' in Roo shell, but I have no idea what should be the next step.</p>
  
  <p>The version of Roo is 1.2.2</p>
