Rally App SDK 2.0: rallymultiobjectpicker fails to load option text - javascript

I am having an issue with the rallymultiobjectpicker, where there is a lack of option text loaded, so there is this banding effect with the list items and their checkboxes. There are no errors in the console, so I have no idea what is wrong. I have tried to minimize the amount of config options specified to the basic modelType, but the issue still persists. I am using it to display tags, if that should make any difference. It seems to work in a standalone app, but I don't see why any of the other components in the larger app would cause loading conflicts, and not throw any errors.
Here is an image depicting the issue: http://i.imgur.com/kqXR0.png
Note: I guess I should note that this was in preview 1. They seem to load fine in preview 2. I am not sure if there is a recommended fix for preview 1. Please let me know.

Thank you for pointing this out and for clarifying the behavior is restricted to 2.0p1. I don't believe that a fix will be forthcoming for preview 1 - the developers are currently working hard on 2.0p3, which will have a number of enhancements and bug fixes. I'd recommend keeping an eye on http://developer.rallydev.com for the latest and greatest version during the preview period and updating your code to match.

rails 4.2 tinyMCE gem produces failed to load content css skins/lightgray/content.min.css

I just introduced tinyMCE into my rails 4.2.8 site to let manage formatted text in articles. Everything works fine actually but now and then a warning message produced by tinyMCE comes up such as "failed to load content css: http://myurl/assets/tinymce/skins/lightgray/content.min.css" but if a look at the debug console in firefox I see that url has perfectly found and loaded content.min.css.
When the warning message is there I can't enter anything in the textarea but the situation is fixed by reloading the page, then the rich text can be nicely entered and the relevant data is loaded correctly into the backend DB via relevant input form.
I don't understand the reason why tinyMCE is signalling such a warning despite the fact that the css file was actually found.
Any idea? Thanks and kind regards
Vincenzo
**** update on June 8th 2017 ****
Now I can better explain what's actually going on.
1) the problem shows up in Firefox v.53, if I use Chrome everything works fine
2) I am using tinyMCE in three distinct forms: one for new articles, one for editing, one for comments.
3) If I insert a few new articles no problem appears, the problem shows up just chenging the form in use: i.e. after insertion an article I try editing it or another one or else I try to insert a comment after havine inserted a new article. After the error message has shown I can always recover by reloading the page and no error appears eventually.
I guess there is some caching problem specifically in Firefox since all works fine in Chrome. I will try Windows Edge too..

Tried Windows Edge on Win10: it works fine too.

In the meantime I opened bug 1371910 at https://bugzilla.mozilla.org/show_bug.cgi?id=1371910#c5 a few days ago and the result was:

Hi Vincenzo,
Thanks for sending us the link. Unfortunately this seems to be a problem with tinyMCE rather than Firefox.
The initial load of content.min.css works correctly, and no other attempts to reload it seem to be made.
If it works in other browsers it is probably due to the developers doing things differently.
If you still think this is a bug in Firefox, please reopen this bug, and send us a smaller test case.
PS. Others seem to be having the same problem as you: https://community.tinymce.com/communityQuestion?id=90661000000Qct9AAC
I hope you find a way to fix it.
UNQUOTE
What the Firefox support says makes sense since I too whatched the content.min.css file was actually loaded by the browser so in must be tinyMCE to misinterpret something. Anyway I am still in the soup...
Whoever might have some interest at this issue please hava a look at:

Javascript game does not load sprites but loads arena

https://github.com/mliu95/quintus-tag
Source code is there.
I was following Liu's tutorial on this (https://mliu95.github.io/2014/09/16/Creating-an-online-multiplayer-web-game-using-Socketio-and-Quintus-Part2/)
Part 1 worked perfectly fine (single player with a movable sprite). However, upon introducing multiplayer (accomplished by opening multiple windows with localhost:8080), the sprites simply don't appear on the screen.
Also, you are dealing with a complete noob in terms of networking. I know a decent amount of Java but have no experience whatsoever. Any advice would be greatly appreciated.
You didn't give much information to go on, and didn't respond to my question in the comments that could clarify the issue.
But here is what I think is happening, in part one of the tutorial he lists his sprite paths here:
var files = [
'/images/tiles.png',
'/maps/arena.json',
'/images/sprites.png',
'/images/sprites.json'
];
I'm assuming your sprites are 404'ing (not being found), so here is a possible fix.
Your file structure is probably not the same as his, where are you storing the sprite images locally (on your pc)? It needs to be in the same paths as shown above. Sprites should be located in YourProjectFolder/images. Make sure your your sprite file is named sprites.png
After making sure all those files are placed correctly, open your developer tools (f12), head to the network tab, check the "disable cache" box (if you're on chrome). And refresh.
It should load your sprites after these changes, and if not, you need to post the specific errors you are running into. The errors will show up in developer tools after you refreshed, if it is still unable to find them.
Good luck

Using Chrome Dev Tools to find out what's causing FOUC

I have been fixing up a sites JS, moving it to the bottom, minifying, etc. And it's all gone okay except on the blog (of an e-commerce site), as the page loads it's causing the header to be un-styled for a second or so, but it isn't happening on any other part of the site, even though they share the same CSS/JS. The blog is image heavy, but with images disabled (and I've tried disabling scripts too), it still happens. It's only happened since I've made changes, which I can't revert simply, but the changes are all positive and should help if anything. I can't see any JS causing it (as I removed the scripts to see if it was in there) and it doesn't happen in FF.
I would share a link but it's behind a closed staging server. And I could provide code but I'm not sure what, and there's a lot.
So, I had hoped I could use Dev tools to figure out what's happening, possibly the timeline view or something. I just don't know how I'd go about doing that.
Any advice?
Ed: I used the network tab on both the staging and the live site, as you can see from the image, they're identical, the css is the first thing loaded after the actual page, and on the live site it's actually ga.js. So it's even more of a puzzle now...
Don't worry, figured it out... It was the Stylebot Chrome Extension.. No idea why it was causing it now after making those changes though, and why it didn't affect the live site. I had no styles defined in it for this domain. A bug I guess.
Cheers all the same :)
Timeline tab in the dev tools is for benchmarking / site performance testing. If you want to know what's happening as in what content is being loaded, when and where, you can use the network tab for that.
It's also a common practice to stuff console.log() everywhere with some relevant message so you know when some part of code is being run.

Youtube, the site itself freezing for a few seconds

i've been plagued by a problem that seem to started since Youtube's last
layout change this year.
I have for months put up and tried to ignore the freezing that happens
everytime I open a link within youtube such as an channel, an video, the homepage, etc.
I'm using Chrome version 31.0.1650.63 and I have already tested youtube without any
extensions, cookies, cache, etc but it still affects me to this day and maybe some
of you out there.
I searched every where for the solution and couldn't find any anywhere.
I did a bit of digging and testing to see what is the root of the problem and
while i'm no expertise on code or Java...I did found something.
Every time I reload a page on youtube, with it finishing loading up...this happens:
http://i.imgur.com/K9Z3vJ1.png
See that?
The purple-colored rendering, that's the cause of the lag every time I load
up something on youtube!
I notice that it repeats the same thing over and over again for like 5-15 or so
seconds before it starts loading up the thumbnails of the videos.
If you want a closer inspection of the code, here's the raw data from the timeline (that you can load up in chrome's dev timeline window):
Youtube Lag JSON Timeline file
I don't what to do with this problem and I believe it affects
me in Firefox as well but to an lesser extent then chrome.
Do any of you guys know how to resolve this problem?
Honestly I doubt that the youtube devs will fix this problem since they're the ones who caused it in the first place. (Like not being able to subscribe to some people when i'm not even at my sub limit.)
I'm sorry if you don't want to help but I don't know who else to look to besides
the experts that y'all are when it comes to web coding. If anything, I believe a userscript or something similar could help with this but how...I don't know.
I'm new to this and I apologize if the question i'm asking isn't suited for this site.
Still, thanks for reading and if you can...please reply.
That is all and thanks again.
Well I was fiddling around and looking at the source code
with chromes timeline devtools and well...
I found a temporary solution to the problem which seems to have
fixed and ended the freezing on youtube! yay~
But some things don't work with this solution and i'm at
a fault with this issue after some hours trying to figure out
how to stop the problem.
Anyways I used adblock, an extension that I have on Google Chrome, to deal
with this issue and was able to get everything fixed and working!
What I did was, in the custom filters section (check options in your
adblock extension, you should have it.) and added the following then did
some testing to see if it fixed the problem which it did!
Here are the filters I used to fix it!
||s.ytimg.com/yts/jsbin/www-pageframe-*
*www-pageframe-*.js
^^^
Yeah, that's the temporary solution as it fixes the problems but it causes the following...
You can't open the menu which contains links to your playlists, user settings, channel, etc when you click your username or profile
picture on top right of youtube.
The "..." mini-menu that you usually find on the right of a video section (to hide, subscribe, etc.) doesn't appear anymore.
Youtube's quick menu button doesn't work, however the menu is still open but you won't be able to close it. That or it's close and you
won't be able to open it...I guess.
Those are the problems I found with this temporarily solution to the freezing problem.
Yeah...but I hope this helps anyone who's having this problem somewhat well.
But it would be nice if someone has an better solution then mine hehe!
Thanks for reading and if you have a better solution, don't feel afraid to
tell! ^_^
I'll be awaiting other answers, for now...I hope this helps y'all well
in some ways hehe! =D
This certainly isn't javascript, but substituting the normal EasyList in ABP for EasyList without element hiding will fix the issue. There are downsides to this as well but for now seems to be the better solution.

Sometimes FCKeditor doesn't load in Firefox

I am unable to replicate the problem when I want to but it seems like every now and then, my site using FCKeditor will load the interface but not the content (Clicking the buttons don't do anything). No javascript errors show and once it starts doing it, it usually is tough to get back to normal. The way I found to work best is to click the refresh button multiple times in a row, then the FCKeditor loads correctly. I have only seen this in Firefox
Has anyone else run into this problem or know a solution. It is a little annoying for me but I am afraid my client would be really confused
I have experienced the phenomenon you describe in FCKEditor's successor, CKEditor. Somehow, the IFRAME that contains the WYSIWYG content doesn't get loaded. What always helps is switching to source code view and back, but that's no solution.
I have seen the problem described on the Internet but with no solution.
Caching is not the problem, I think. Sometimes, if you press "reload" 20 times, it will break at the 21th time, and work again on the 22nd time.
What minimized the number of occurrences for me was to activate the thingy to the editor's bottom that shows the element path (body > p > span, I forgot it's name). I don't now why but since I turned it on, it very rarely breaks any more.
I have had this problem. I solved it by pre-loading FCKeditor in a hidden iframe during the login process so that when it got to the pages where it was used it was already in the cache.
i would strongly advise to upgrade to CKEditor which can not only be spelled out verbally without offending anyone, but also optimizes the loading time to minimal. I find it much more responsive than his F- friend.
I encountered this problem with firefox (not reproducible) and chrome (reproducible).
The solution that worked quite well in both cases was to wait for some milliseconds before initializing CKE :
setTimeout(function() {textarea.ckeditor({customConfig : 'custom/schnonfig.js'})} , 100);
