The parameters of javascript push must be understanded by javascript. If you look at the javascript code generated, you will probably see something like :

    conditions.push(HighlightVO@6d06d69c)

which is not understanded by javascript.

A solution is to implement the toString() method of HighlightVO in order to return the object in json format.

Adding toString method in HighlightVO class :

  public String toString()
  {
    return '{'+
           'field1:'+field1+','+
           'field2:'+field2+','+
           ...
           '}';
  }

will generate :

conditions.push({field1:1,
                 field2:'2', ...})

Thanks for the solution. – Maulin Patel Apr 12 '17 at 10:13 — Maulin Patel, Apr 12 '17 at 10:13
