Sharepoint 2013 search: how to make refiner update 2 search web parts

So my case today is having a nice Search Results Page, with a nice Search Results WP and a Refinement WP updating him.

now i added another Content Search WP, and Oh My! it doesnt updates!
since i am used to MS giving a lot of work to developers, that looked like a nice challenge, some advanced client-side Search-Controls work.

so...

1 - Get the new query

that part is easy - its up in the url, with a simple regex i took it out

var rgx = /#Default={[{":,\\}()#\-\[\]a-zA-Z0-9]+}/;
var queryObjStr = decodeURIComponent(window.location.hash)
                     .match(rgx)[0].replace("#Default=", "");

2 - Send it to our control

well, MS did gace us some nice Client-Side API, one of the SRCH objects is the QueryState, which is actually the object in the Default up in our hash

var queryState = JSON.parse(queryObjStr);
var queryStateArgs = new Srch.QueryEventArgs(queryState);
 
//and tell our control to update

var cc = ctx.ClientControl;
cc.raiseQueryReadyEvent(queryStateArgs)

basically if you need some very specific logic you can end reading here.
also note that the you can create your own QueryState object and fill it as you wish like here, just google it a bit.
but......

3 - Put it in your Control Display Template

but i want my WP to be independent, meaning that wherever i throw it around it will know what to do, i.e. update itself from the page refiners.

so obviously i want to put all this login in my Control Display Template

AddPostRenderCallback(ctx, function(){
   $('a[id=FilterLink]').on("click", function(){
      console.log('u clicked me!!');

      var rgx = /#Default={[{":,\\}()#\-\[\]a-zA-Z0-9]+}/;
      var queryObjStr = decodeURIComponent(window.location.hash)
                          .match(rgx)[0].replace("#Default=", "");
      var queryState = JSON.parse(queryObjStr);
      var queryStateArgs = new Srch.QueryEventArgs(queryState);
              var cc = ctx.ClientControl;
      cc.raiseQueryReadyEvent(queryStateArgs);
   });
});



so...that should have done it... but....

4 - The "Bugs"

I. After one click it doesn't work again
II. Sometimes it doesn't catch the Refiner Control/s
III. The script never Runs if no initial results

well, for bugs I and II i created a nice interval system, shown immediately, but for III its simple, in the WP Properties uncheck "Dont show anything when there are no results"



for the rest, the point is that all this stuff happens ASYNC, and i found no "OnPostEverything" event or callback, so i just used an interval

var overloadRefiners = function () {
  console.log('overloading Refiners : ' + $('a[id=FilterLink]').length);
  var setRefinerOn = function () {
    console.log('setRefinerOn, attempt ' + window.setRefinerOnCount);
    if (++window.setRefinerOnCount > 5) {
      console.warn('clearing window.setRefinerOnCount after 5 tries');
      clearInterval(window.setRefinerOnInterval);
    }

    if ($("[refinername]").length === 0) {
      console.warn('overloading Refiners : no refiner found');
      return;
    }

    $("[refinername]").on("click", "a[id=FilterLink]", function () {
      console.log('overload Refiner click')

      var rgx = /#Default={[{":,\\}()#\-\[\]a-zA-Z0-9]+}/;
      var queryObjStr = decodeURIComponent(window.location.hash)
                          .match(rgx)[0].replace("#Default=", "");
      var queryState = JSON.parse(queryObjStr);
      var queryStateArgs = new Srch.QueryEventArgs(queryState);

      var cc = ctx.ClientControl;
      cc.raiseQueryReadyEvent(queryStateArgs)
    });

    clearInterval(window.setRefinerOnInterval);
  };

   window.setRefinerOnCount = 0;
   window.setRefinerOnInterval = setInterval(setRefinerOn, 100);
}//end overloadRefiners

AddPostRenderCallback(ctx, overloadRefiners);

OverTheWire[.com] Natas Walkthrough - JUST HINT, NO SPOILERS

game portal: http://overthewire.org/wargames/natas/ PASSWORDS for each level are stored in /etc/natas_webpass/natasX I made this walkthrough for people like me, i needed some help, but didnt want the spoiler, so here i will give you all the information needed to pass each level, yet not the solution. For levels needed custom web request i made a different post for powershell and javascript  with how-to's, since is a piece of learning for itself, and also for those of us that play at work and have only powershell at their hands. Although its not a complete spoiler there, its quite most of the solution so try yourself 1st. Natas The Natas game is from basic to advances web hacking. Every few levels is about whole new exploitation (with some harder ones doing comeback later), so a lot of learning. If you're new, you're the reason i am writing so much even for the 1st level, just please google EVERY topic you see, since in the following levels i assume you know the

Asp.Net Ending Response options, Response.End() vs CompleteRequest()

this blog is for any1 who get the ThreadAbortException when caling Response.End(), and then tried the other options such as HttpContext.Current.ApplicationInstance.CompleteRequest() and found out that there was no replacement. i'll start with the bottom line: if you want to stop right now your response and send it as is you dont have any other option other than Response.End(), period and it's the right thing to throw that EX in that case. the answer is its because there is the "HTTP pipeline" and the "Asp.Net pipeline", and CompleteRequest() cuts the HTTP pipeline but not the Asp.Net one so everything that is from handlers forwars (including all page events) continues but your part, the asp one, stays in your hands so that no information will be lost, so ur suppose to manage your code currectly, since information lost is really a bad thing, although in most cases we use Response.End() we know what we are losing and we want it. see this short article ab
