Re: [xwiki-users] Livetable events

29 Aug 2015

      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.
