Understanding JSFs options.params in jsf.ajax.request - jsf-2.2

We migrated our JSF 2.2 based application to JSF 2.3, Except of some smaller issues we were able to get everything up and running. For one view we use Butterfaces JSF component, especially the tree component. With JSF 2.3 it was not possible to select a node and to show details of that node in another container. The apprropriate Ajax request sends the id of the node as options.params. That worked fine with JSF 2.2 but is not working anymore with JSF 2.3. We are still on Butterfaces 2 ( which should work due to downward compatibility), but even in the showcase of Butterfaces 3 on Java EE 8, the select via Ajax seems not to work.
I had a look on the jsf.ajax.request Javascript method of JSF 2.3, debugged it and realized, that the param was ignored and deleted since it seems to be the wrong format. Thus, I monkey patched the method in our application with this little stupid code snippet, to get the param sent to the server via the ajax request:
var originalJsfAjaxRequest = jsf.ajax.request;
jsf.ajax.request = function (source, event, options) {
options.params = {params: options.params};
originalJsfAjaxRequest.apply(this, [source, event, options]);
}
That's it, it is working fine again.
So my question is, where the problem is supposed to be. Is it a problem in JSF to ignore these sort of params. Or is it a problem of Butterfaces using the parameters in a wrong way? What is the correct way, to use options.params?
Thanks in advance

I don't know why, but JSF 2.3 ignores param attribute when using jsf.ajax.request. There is an ButterFaces issue: https://github.com/ButterFaces/ButterFaces/issues/232 and a new release will be released this or next week.

Swashbuckle.AspNetCore .NET 6.0 blank swagger site

I am trying to setup swagger for the product I'm developing and cannot wrap my head around it.
I started with the most basic config as described here. The swagger.json was generated correctly under https://localhost/MyWebAPI/swagger/v1/swagger.json, but when navigating to https://localhost/MyWebAPI/swagger/index.html I get a blank site. Did some digging and most of the answers were revolving around setting up SwaggerEndpoint, RoutePrefix or some uri templates but none of them worked for me so I finally did what should have done in the first place and checked code of the site itself.
It is there... The url's seems correct:
var configObject = JSON.parse('{"urls":[{"url":"v1/swagger.json","name":"MyApp v1"}],"deepLinking":false,"persistAuthorization":false,"displayOperationId":false,"defaultModelsExpandDepth":1,"defaultModelExpandDepth":1,"defaultModelRendering":"example","displayRequestDuration":false,"docExpansion":"list","showExtensions":false,"showCommonExtensions":false,"supportedSubmitMethods":["get","put","post","delete","options","head","patch","trace"],"tryItOutEnabled":false}');
var oauthConfigObject = JSON.parse('{"scopeSeparator":" ","scopes":[],"useBasicAuthenticationWithAccessCodeGrant":false,"usePkceWithAuthorizationCodeGrant":false}');
// Workaround for https://github.com/swagger-api/swagger-ui/issues/5945
configObject.urls.forEach(function (item) {
if (item.url.startsWith("http") || item.url.startsWith("/")) return;
item.url = window.location.href.replace("index.html", item.url).split('#')[0];
});
The issue is and I kid you not the line with interceptors that is actually split into several lines and the browser wouldn't recognise it as a correct string.
Obviously I tried to pass null as the entire section, but that just brakes everything two lines later. I am in shambles...
I tried with several versions of Swashbuckle (currently using 6.5.0, but tried with some previous ones starting from 6.1.5). Any ideas how to fix it as I guess this must be generally working but there's just something weird/wrong that I'm missing.
Right... one of the most stupid things I've encountered lately. I started reading Swashbuckle source code and the only class that when serialised wouldn't get the JsonSerializerOptions as defined in Swashbuckle project is InterceptorFunctions, so it used mine... and mine would have WriteIndented set as true...

How to destroy dropdzonejs?

How to destroy dropdzonejs?
When I have SPA and leave the page, I want to clean up so it does not listen to body events anymore.
myDropzone.destroy();
I swear I had the same problem and I'll find that with a
lucky attempt... it works!
I removed removedfile() function from Dropzone options and myDropzone.destroy(); worked for me.
According to the documentation:
If you do not need a dropzone anymore, just call .disable() on the
object. This will remove all event listeners on the element, and clear
all file arrays. To reenable a Dropzone use .enable()
If you initialize dropzone like:
var myDropzone = new Dropzone("#mydropzoneid", { url: "/some/url"});
You should be able to disable it with:
myDropzone.disable();
Use one of the following methods : The destroy() and disable() methods both exist, and they seem to act the exact same way.
In fact, DropZone does not have a real destruction method. These methods will "put the instance in pause" (what is, by design, the closest implementation of a DropZone instance destruction).
This applies to DropZone 5.x and DropZone 6.x (try myDropzone.disable() or myDropzone.destroy() in the console on this v6.x example page https://www.dropzone.dev/bootstrap.html) : The DropZone instance will be disabled, thus leading to the "Add Files..." button being inoperative.
The instance can then be re-enabled by calling myDropzone.enable().
PS : DropZone switch from v5 to v6 in 2021-2022. The website was completely revamped and screwed-up: the documentation is partial, incomplete, too short.
If you still need to access the excellent and exhaustive v5 documentation, you can head up to the obvious Web Archive Wayback machine ! Here is the very latest v5 documentation page https://web.archive.org/web/20210829160314/https://www.dropzonejs.com/
If you want destroy all dropzone instances just add if (Dropzone.instances.length > 0) Dropzone.instances.forEach(dz => dz.destroy()) to document ready.

How to access session from a view in ASP .NET Core MVC 1.0

I am trying to access session data from inside a view.
Use Case: I'm storing status messages in the session that will be displayed at the top of the page. Currently I implemented this by using a DisplayMessages() function that sets some ViewData[....] properties and calling it at the beginning of every controller action.
Goal: I want to only set the status message once without needing additional code in the controller to display the messages on the next page load.
So I'm trying to access the messages that are stored in the session directly from the view.
So far I have tried the following:
Dependency Injection of an IHttpContextAccessor (doesn't seem to work anymore with ASP .NET Core MVC 1.0.0
Creating a static class to access the session, including the change from next() to next.invoke() suggested in the comment
This didn't work. I could access the HttpContext and Session.IsAvailable was true, but there was no data in the session.
The following should work in the view: Context.Session.TryGetValue
If you are using the SessionExtensions then Context.Session.GetString will work.
Injecting IHttpContextAccessor does work, but starting with ASP.NET Core 1.0.0 RC2, the IHttpContextAcessor is not registered by default, because it has significant performance overhead per request. See this GitHub announcement for more information.
Tratcher posted:
IHttpContextAccessor can be used to access the HttpContext for the current thread. However, maintaining this state has non-trivial performance costs so it has been removed from the default set of services.
Developers that depend on it can add it back as needed:
services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
But in your use case, I would suggest using a ViewComponent, which is a reusable piece of View with logic, that do not depend on a controller.
The documentation can be found here.
In your Views you would simply embed it with
#await Component.InvokeAsync("PriorityList", new { maxPriority = 2, isDone = false })
or
#Component.Invoke("PriorityList", new { maxPriority = 2, isDone = false })
for synchronous calls.

How does React deal with pre-compiled HTML from PhantomJS?

I compiled my reactjs using webpack and got a bundle file bundles.js. My bundles.js contains a component that make API calls to get the data.
I put this file in my html and pass the url to phantom.js to pre-compile static html for SEO reasons.
I am witnessing something strange here, the ajax calls for APIS are not getting fired at all.
For example, I have a component called Home which is called when I request for url /home. My Home component makes an ajax request to backend (django-rest) to get some data. Now when I call home page in phantomjs this api call is not getting fired.
Am I missing something here?
I have been using React based app rendering in Phantomjs since 2014. Make sure you use the latest Phantomjs version v2.x. The problems with Phantomjs occur because it uses older webkit engine, so if you have some CSS3 features used make sure they are prefixed correctly example flexbox layout.
From the JS side the PhantomJS does not support many newer APIs (example fetch etc.), to fix this add the polyfills and your fine. The most complicated thing is to track down errors, use the console.log and evaluate code inside the Phantomjs. There is also debugging mode which is actually quite difficult to use, but this could help you track down complex errors. I used webkit engine based browser Aurora to track down some of the issues.
For debugging the network traffic, try logging the requested and received events:
var page = require('webpage').create();
page.onResourceRequested = function(request) {
console.log('Request ' + JSON.stringify(request, undefined, 4));
};
page.onResourceReceived = function(response) {
console.log('Receive ' + JSON.stringify(response, undefined, 4));
};

Wibiya toolbar breaks Drupal quicktabs

I have the Drupal Quicktabs module installed at:
http://ar.sacherokeedev.com/auction-directory
I've also installed the wibiya toolbar, http://www.wibiya.com.
Everything works fine in Firefox and Chrome, but in IE7, with the toolbar enabled, it breaks the ajax tab loading. With the toolbar disabled, IE7 works fine. Wibya has a "Javascript Conflict" mode, and I've tried that as well as changing my DocType, as they suggest.
I've narrowed it down to a couple of things. First, quicktabs behavior is based on the "type" of the tab:
if (tab.tabObj.type != 'view') {
// construct the ajax path to retrieve the content, depending on type
var qtAjaxPath = Drupal.settings.basePath + 'quicktabs/ajax/' + tab.tabObj.type + '/';
switch (tab.tabObj.type) {
case 'node':
qtAjaxPath += tab.tabObj.nid + '/' + tab.tabObj.teaser + '/' + tab.tabObj.hide_title;
break;
case 'block':
qtAjaxPath += tab.qtid + '/' + tab.tabObj.bid + '/' + tab.tabObj.hide_title;
break;
case 'qtabs':
qtAjaxPath += tab.tabObj.qtid;
break;
}
In my case, when using the toolbar in IE, tab.tabObj.type is "undefined". So, I'm thinking that wibiya is hijacking my objects or something.
I also get a runtime error, "Object does not support this property or method" in the following block:
if (!Drupal.quicktabs.scripts[files[i]] && !files[i].match(/^\/misc\/jquery\.js.*$/)) {
Drupal.quicktabs.scripts[files[i]] = files[i];
html += '<script type="text/javascript" src="' + files[i] + '"></script>';
}
Has anyone seen this before, or have any suggestions?
Update: I did console.log(tab.tabObj) and in Firefox and Chrome, I get something that makes sense, an Object with a block id, a type, etc... But in i.e. I get this:
function(fn,thisObj){var scope=thisObj|window;for(vari=0,len=this.length;i<len;++i){fn.call(scope,this[i],i,this);}}
Anyone have any ideas?
UPDATE: I am currently using the Drupal specific wibya module, and the toolbar itself works fine on my site whether one is using IE, Firefox or Chrome. The issue is that the ajax tabs on that page are prevented from functioning by the wibiya toolbar. I'm inclined to agree with #clive that it's a jQuery/javascript conflict, but I'm not sure what I can do about it.
As for running Drupal 6, I inherited the system, and as of now, can't upgrade.
UPDATE: I just tried loading jQuery 1.4 using the instructions at http://drupal.org/node/1058168. That caused IE to work properly, but now Chrome and Firefox don't like it.
UPDATE: This is a conflict between jQuery 1.3 which runs on Drupal 6 and the Wibiya toolbar which uses at least 1.4. I'm accepting #clive's answer, mainly because he's right about the fact that this is just something that I'm going to have to live with if I have to keep using Drupal 6.
My best guess would be that you're using Drupal 6 which ships with jQuery 1.2.6 (or 1.3.2 with the jQuery update module. The Wibiya baar conversely uses jQuery 1.4.2 upwards.
According to a page on the Wibiya support forums (which I'm sure you've already seen):
if page loads another version of jQuery like 1.2.6 or 1.3.2 previously, Wibiya bar's loading of its own jQ 1.4.2 does not work. No bars, nothing.
But if you load your own jQ 1.4.2 in the first place, then your bar works, despite all other Drupal functions suck like polls, votes, hierarchical select tags, nice menus, some collapsibles, etc.
There a lots of these types of problems with Drupal which is why the community comes up with workarounds and solutions: The Drupal specific Wibiya module will probably save you a lot of headaches.
UPDATE
There's a JS error on your site:
Unsafe JavaScript attempt to access frame with URL http://ar.sacherokeedev.com/auction-directory from frame with URL http://ad.doubleclick.net/adi/N1727.autoremarketing.com/B5111890.6;sz=728x90;click=http://adclick.g.doubleclick.net/aclk?sa=L&ai=B6dLCjz5qTqvUGIfN0AXN67WqBa-C-usBAAAAEAEg7ZqAFjgAWK_Q_80gYLu2moPQCrIBFGFyLnNhY2hlcm9rZWVkZXYuY29tugEJZ2ZwX2ltYWdlyAEJ2gEtaHR0cDovL2FyLnNhY2hlcm9rZWVkZXYuY29tL2F1Y3Rpb24tZGlyZWN0b3J5mAKgjQbAAgLgAgDqAhNBUl9Ib21lX0xlYWRlcmJvYXJk-ALw0R6QA4wGmAPgA6gDAeAEAaAGFg&num=0&sig=AOD64_1Xi82LSwUc1kKF0RL_orTztOMfxg&client=ca-pub-2649455708539916&adurl=;ord=1670303729?. Domains, protocols and ports must match.
Is it possible that unsafe frame attempt is stopping IE7 from processing the rest of the JS, thereby making your tabs not work?
