Ok, I think this is just a race condition, with the event listener typically being
registered after the livetable has been created and populated. Explicitly refreshing the
table with the following makes the rows display correctly:
     var lt = window[lt_name];
     var end = lt.limit;
     var start = Math.max(lt.lastOffset, 1);
     lt.clearCache();
     lt.getRows(start, end, start, end);

So instead, here's another question for LiveTable gurus: Is there a way to prevent a
livetable from updating? I'd like to place the LiveTable in a div that is initially
hidden, and I only want it to be active when the div is made visible.

Thanks,

Bryn

 I've been following the instructions in
 http://platform.xwiki.org/xwiki/bin/view/DevGuide/LiveTable to modify the
 contents of a livetable, with the following jQuery:

 require(['jquery', 'xwiki-events-bridge'], function($) {
   document.observe("xwiki:livetable:newrow", function(ev) {
     $('.working').each(function () {
        var txt = $(this).text();
        if (txt== "true") {
           $(this).append($("<span>", {
             class: "glyphicon glyphicon-ok"
           }))
         } else if (txt == "false") {
           $(this).append($("<span>", {
             class: "glyphicon glyphicon-remove"
           }))
         }
      });
     document.fire("xwiki:livetable:ready", {});
   });
 });

 However, this only appears to work once I cause the livetable to update after
 it has loaded the first time (e.g. by sorting a column). How do I get it to run
 the first time?

 Also, what is the purpose of the last line?:
 document.fire("xwiki:livetable:ready", {}); This appears in the example code
 "Display ratings in the Livetable on row event", but doesn't obviously
affect
 anything if I remove it.
