title: How do I render a field in the gsp page from another domain?
body: <p>Here is my scenario:</p>
  <pre><code>Class Domain1 {
    static hasMany=[ tests : Domain2 ]
    static constraints = { tests(nullable: true) }
  }
  </code></pre>
  <p>And</p>
  <pre><code>Class Domain2 {
    Double t1, String t2
    static constraints={
      t1(nullable:true
      t2(nullable:false,blank:false)
    }
  }
  </code></pre>
  <p>I need to display t1 from domain2 in domain1 with the ability to edit.</p>
