livetable returns only first object

When using the class filter in the livetable options, a document with multiple objects of the filtered class will be returned multiple times, but every time with the first object.

Steps to reproduce

The following steps use the AnnotationClass as an example, but you can use any other class.

1. Create a page with the following code:

   {{velocity}}
   ## Replace the AnnotationCode.AnnotationClass class and annotation property with your class.
   #set($columns = ['annotation', 'doc.name'])
   #set($columnsProperties = {
     'annotation'  : {'type' : 'text' },
     'doc.name': { 'type' : 'text', 'link' : 'view' }
   })
   #set($options = {
     'className' : 'AnnotationCode.AnnotationClass'
   })
   #livetable("projectTable" $columns $columnsProperties $options)
   {{/velocity}} 

1. Add two AnnotationCode.AnnotationClass objects on the same page, with different values for the Annotation field (ex. "Object 1 annotation" and "Object 2 annotation")
2. Save and view

Expected results:

The livetable lists each object on the page. (So both "Object 1 annotation" and "Object 2 annotation" are visible)

Actual results:

The livetable lists the first object multiple times.
