Re: [Rails-spinoffs] onCreate not getting triggered.

Ya ended up going with onLoading as well. At least for now.

Now my problem is that my server/application is to fast!! (go figure)

I am displaying my "loading" graphic to the user on the "onLoading" and then hiding it on "onComplete" but the thing just flashes for les than a second and is all but useless.

Has any one come up with a good solution to only show the loader if the request is taking more than X seconds or something??

Thanks.

It seems like onCreate only gets called like so in prototype:
Ajax.Responders.dispatch('onCreate', this, this.transport);

In other words, only the global responders will get it.

I'm with you though in wanting a reliable onCreate to happen before
looking at the readystate events.

I've been using onLoading for awhile, but I'm testing right now with a
local webserver and can actually reproduce the race condition whereby
onLoading gets triggered after onComplete by sticking console.debug(
event) on line 765 of prototype.js.

What is anyone else doing? I'm thinking of just adding a similar line of
code for onCreate like onComplete so that the instance of the
AjaxRequest can name it's own onCreate and the responders will still get
called. But I'd of course rather not edit prototype.js.

I am trying to get a loader to display during ajax requests, but the
"onCreate" is not getting triggered. The onComplete does.

function loadComponent(section){
values = arguments[1]
pars = $H(values).toQueryString()
pars = "section="+section+"&"+pars
var url = '';

var ComponentLoader = new Ajax.Updater('maincontent', url, {
asynchronous:true,
onCreate: function() { loadingRequest('mc_loader',
'maincontent'); },
onComplete: function() {
completedRequest('mc_loader', 'maincontent'); },
method: 'post',
parameters: pars,
evalScripts: true });
}

function loadingRequest(loader, target)
{
   alert("request started");
   new Effect.Appear($(loader), {duration: 0.5});
   $(target).style.display = "none";
}

function completedRequest(loader, target)
{
   alert("request Done");
new Effect.Fade($(loader), {duration: 0.5});
   new Effect.BlindDown($(target));
}

Can any one see what I am doing wrong?
