Is there a "right" way to make a LiveTable refresh?
I have a page that includes a LiveTable to show the results of a query on an external
database, and a form triggers an AJAX call to modify the database (e.g., insert a new
row). I'd like the AJAX call to include an action within OnSuccess to make the
LiveTable refresh to show these modifications.
http://xwiki.475771.n2.nabble.com/Proposal-Hightlight-applied-filters-in-li…
and
http://jira.xwiki.org/browse/XWIKI-5100
appear to discuss something of this kind, but I couldn't find any instructions. The
closest thing was a line in livetable.js
https://github.com/xwiki/xwiki-platform/blob/4f92c9fc4dc9d4bb7b42a54f3e289f…
where it looks like a refresh is triggered on event
"xwiki:livetable:mylivetable:filtersChanged". I have tried calling
document.fire('xwiki:livetable:mylivetable:filtersChanged');
from within a javascript function, but this did not appear to make the
"mylivetable" LiveTable update. Could anyone direct me further?
Thanks,
Bryn

I do not know of a "right way", but one that currently works is to fetch the
livetable by its name, and refetch the current rows via some not-so obvious code,
like:
var livetable = window['livetable_'+ id_of_livetable_here ] ;
var end = livetable.limit;
var start = Math.max(livetable.lastOffset, 1);
livetable.clearCache();
livetable.getRows(start, end, start, end);
That works in some little extension I wrote:

I think I even "borrowed" it from some other xwiki-contrib code, but cannot
remember from where.
Certainly this is not "using any API" and it is expected to break without notice
in any new XWiki version, but for now it does the job (for me at least).
Sure there is a better way, to do this, (or at least it should ;)) but I do not know about
it.

That did it, thanks.
It does seem like it would be easier if the livetable could listen out for a
reset event, since it already listens for others, but I couldn't get any
other way to work.
