While developing a website I experience a weird bug.
From time to time my images or my css are missing.
It's not really predictable and therefore not reproducible.
Usually it happens after I edit my css, save it and reload the page (in the browser).
It's always syntactical correct CSS, so no compilation erros or anything similar.
I think it's the way Grails updates the running application, but I really can't say why or where it happens as it is quite rarely, but definitely annoying.
It doesn't matter if I run the application with my IDE (IntelliJ 9.0.4) or with the commandline (Windows).
The only thing I did not test so far is whether it happens only when I use the IDE or not.
Did anyone experience this?
EDIT:
Sorry for an unclear description:
"missing" means the browser is unable to load the corresponding ressource: "The Ressource () is not available"
Another Edit:
Thanks for the comments so far.
In addition to my main css-file and my images, which change quite frequently, my reset-css-file disappeared. I never touched it since creation, so I think one can exclude the compilation-script as cause of this mess. (further info in the comments)
Like John Smith I arrived here googling for this problem.
But I found another solution, and i hope that it helps you too.
I googled a little bit more and found this discussion Disabling static resource stuff, here i found a contributor of grails application, and author of Resources Plugin, Mark Palmer (take a look his website), telling what he is doing and answering the questions about this plugin.
Today, all you need to do is to update the Resources Plugin to version 1.2-RC1 or a recent one that will fix this problem.
When you say missing, do you mean that the changes are missing, or the whole stylesheet is missing? If it is just your latest changes, it is possible that your browser is caching the previous css file and isn't getting the latest changes. Try doing a "hard refresh" with something like CTRL+F5, or whatever hard refresh is in the browser that you are using. This will force a pull of the latest resources.
Really old question.. but for anybody googling this - I had similar issues with my CSS because of Windows file format on the Linux systems. Once I changed the format to unix, I still had to restart the server for the css to download. Note that somehow the css were downloading earlier although the format was windows and the issue was intermittent.

I'm done with googleing, I have to ask you folks...
I have a static web project (not JavaFX, thus no JavaFX toolkits!) in Eclipse Kepler. Now thats the messy road I went:
I created a .less file (for the first time)
Eclipse starts nagging with the "Do you want to add the LESS-project nature?"-popup
I clicked 'no' 10 times (pops up every time I start Eclipse)
then I clicked 'yes' to add the nature for making this stop (could not find ANY workaround for that #$%!+"* !)
Now I face this travesty:
The built in CSS-editor marks every trivial property as unknown. I have no clue how to fix this. I removed the less-nature and restored my old .project file too but the warnings (and even real errors) persist. I found out that rewriting the properties does not summon these warnings!
No, I won't rewrite ~6000 lines of css...
Please help. Please make it stop...
Sorry, found the solution (dumb as can be):
delete project (only!) in Eclipse
re-import project (which completely revalidates the project structure)
errors are gone...
Although this solved my problem, I feel uneasy about the fact that I could not find any possibility to do a complete re-validation without to delete and re-import my project. This is pretty nasty...
Right click project Configure->Remove LESS nature.
I have a .swf in my rails application, located here:
/public/bin/editor/Editor.swf
It works fine, with one flaw, it gets cached often, so when we release a new version we are usually needing to tell the customers to clear their cache when they experience issues. My question is, how could I force the .swf to break cache when I release a new version? Something like:
/public/bin/editor/Editor.swf?timestamp=124158512132
I tried the above, but it did not seem to work. Any ideas would be great!
if you are using swfobject.js and want the item not be cached you need to add this, to the swf description:
swfobject.embedSWF( 'index.swf ?'+ new Date().getTime()...
of course you can change getTime() to the format you like.
Consider employing a versioning nomenclature to your editor. For example Editor_v1.01.005.swf
Here's a good format
app_major_minor_patch.swf
There are a number of benefits for doing this, and it will also solve your caching issue as well out of coincidence. :)
I had an idea for "cheap" version control of the css of one of my sites, but am thinking it may not be a good idea. Thought I'd throw it out here in case someone has a similar idea that works better (besides real svn, etc.)
My thought was to create a main css file like "sitename.css" then use #import inside this file to connect to the most recent file with updates. I'd name these imported files by date, eg: 20101222_css.css so I'd know when the last update was applied. When I have a change, I could make my edits, drop the update in the respective location, change the #import to the new file, and viola... updated on the site.
After reading about issues with #import, such as it loading AFTER the page finishes, I'm not too keen on this now.
Any ideas of a way to implement something similar without a full blown system? I do a lot of small project work for various people and thought this method may be a simple way to keep track of things.
Thanks for any ideas/suggestions.
Your idea would add additional page loads to your site for no good reason, which will be a performance hit. It would also expose your versioning to the outside world. And as you say it will suffer from slow loading speeds due to the way #import works.
But the real down-side of this technique is that it only works for CSS files. You haven't solved the problem for any other files on your site.
You seem to think it would be simpler to use than a real SVN setup, but if you end up coming up with different techniques like this for every type of file on your site, you could easily end up giving yourself more headaches than you solve.
SVN is actually quite straightforward to use. With a good GUI (try TortoiseSVN), it's so easy you almost forget its there. Seriously, use SVN. There's no need to come up with 'clever' alternatives.
Its not a good idea, especially if you push this into production. If you want "cheap" version control, download VisualSVN. Its free.
The guys at Yahoo use a technique that reminds me of what you describe:
<link rel="stylesheet" type="text/css" href="http://l.yimg.com/a/combo?arc/yui/reset_2.6.7.css&arc/yui/fonts_2.6.4.css&[....]/subfooter_0.0.12.css" />
It makes sense for them because it's a caching tecnique. They set HTTP headers so stuff never expires: if you load the site one year later and you haven't removed your browser's cache, you shouldn't need to fetch again any of the files that haven't changed.
However, it's by no means a sensible version control system. You already have a good bunch of real version control systems out there!
I've got this very odd bug that appears to be a quirk in Visual Studio 2010: Sometimes, when moving the cursor into double quotes of a CSS style="" attribute the cursor refuses to move. I can't type anything, and the keys that respond are the UP/DOWN cursor keys and the DEL key (but not BACKSPACE).
Typing does nothing, but pushing LEFT/RIGHT on the cursor keys produces the following error:
The operation could not be completed
I've got no idea what's causing this, but I would hazard a guess that Intellisense is getting very confused and bugging out.
At the moment, whenever this happens, I have to write any CSS outsite of the double quotes of the style attribute and then place the cursor where I want the CSS to appear (using the mouse) and press CTRL-V to paste it in. Very annoying :(
There must be a way of fixing this problem...?
Hopefully someone has an answer!
Just encountered the issue in VS 2012, in editing C#.
I noticed that the problem had occurred soon after the trial period of Resharper has ended and i inserted a valid license number. It also happened in only some of the source files.
The solution: Tools->Options->Resharper: Suspend.
Try typing - should work now.
Then: Tools->Options->Resharper: Resume.
Problem gone.
I have encountered this using Visual Studio 2013 and Resharper 8.2.1. None of the solutions provided in this thread worked (even suspending and resuming Resharper)
After contacting JetBrains support, it turned out to be a caching issue.
Deleting all the files from the following directory solved the issue, as Resharper re-creates new caches:
C:\Users\[Username]\AppData\Local\JetBrains\ReSharper\v8.2\SolutionCaches\[Project_reference]
I have some odd issues with the editor occasionally, a workaround for me is:
Ctrl-Tab (x2) to another code file and back to the same code (or alt tab to another app and back, one of these two... can't replicate issue to be sure)
An ultimate solution might be a re-install.
Microsoft have had variations on this problem reported quite a few times via their support portal. Here is one post and if you scroll down you will see a comment with a bunch of other reports all detailing similar(ish) problems.
Microsoft doesn't seem to be able to reproduce the problem but are "duping all the similar keyboard locking problems to a central bug, so that we can think a way to log the events if necessary". Which seems to be a generic response to a lot of these posts. Some people reported that it was simply becuase another window/pane/tab was in focus but I can see the OP obviously did not have this specific problem. Looks to me like one of those random unresolvable bugs. Hope I never get it! There's also numerous forum posts around the Internet, where users stated that removing certain 3rd party plugins has solved this issue.
I just spotted this particular post which has a possibly useful comment on it for you (which also link to this SO post. As I do not have the bug I cannot test its validity for you. The main point of it seems to be something about the keyboard layout switching.
I'm sorry for putting all this into an answer when technically it is not an answer and just a mass of research, but there was no way this was gonna fit into a comment. And also sorry for pretty much link spamming, but again there was no way I could extract everything that they said into this post. I hope there is something useful in there for you :)
EDIT: You should probably check the top rated answer below as this seems to solve a number of peoples issues, although I never had the Resharper plugin and still occasionally experienced this, but now I'm on VS2013 and have not had this problem re-occur, so maybe they fixed it...
Empty the solution cache folder
C:\Users\{UserName}\AppData\Local\JetBrains\ReSharper\v8.2\SolutionCaches\
This was suggested by JetBrains support when I contacted them.
Permanently fixing... Not too sure however I found that pressing pressing Ctrl+Shift+Caps Lock+Tab all at once seems to get rid of this and enables the mouse and keyboard again. I know this isn't the best of solutions but it works.
I have the same problem several times a day. I didn't notice it until I installed the web essentials extension. I just uninstalled it and will see what happens. I have tried reinstalling visual studio with no joy (but again, I didn't notice the problem until after I had already installed the various extensions).
Sometimes, closing and re-opening the specific code window I'm working in fixes it. If that fails, sometimes I close all windows and reopen just the one I was actively editing. If all of that fails it usually requires a complete restart of visual studio.
I find it funny that MSFT says that they can't duplicate the problem. Scott Guthrie experienced it first hand during his MVC4 beta demo here at about 28 minutes in.
UPDATE: So far, as of 4-5-2012 9:33am Central Time, the problem hasn't recurred since uninstalling Web Essentials. This is the longest I've gone without this bug occurring. If I make it through the next 24 hours, I'll be confident in blaming Web Essentials.
UPDATE: 4-6-2012 10:05am Central Time: Well, apparently it wasn't Web Essentials. It happened to me again this morning editing the contents of a block in my _Layout.vbhtml file. Closing the tab and reopening it fixed it.
I frequently encounter this editor freeze, not just on CSS quotes but any file arbitrarily. I have a dual monitor setp and I have the doucment windows one one monitor and all tool windows on the next one. Sometimes, certain tool windows would freeze too (i.e. not respond to click).
Previously, I used to shutdown/restart IDE; but serendipitously, I discovered that switching to/from Full Screen mode, restores sanity. So now everytme I see a freeze, mode switching comes to rescue.
Not sure if this will solve your issue, but worth a shot.
Rant: In general, I find this new WPF based product very falky and unstable than its predeccessors.
I have the same problem on IDE, some times the Return key is not working at all...
My solution is: CLEAN the project/solution.
BTW: CLEANing resolve also other unexpected behaviours after amendements on CSS or HTML.
I tried every other workaround here but nothing seemed to work, and the issue was only present in one solution but not another.
Disabling Resharper fixed it temporarily but it came back after re-enabling it which wasn't a viable long-term solution.
What worked for me was disabling all Resharper Extensions (Under Resharper -> Extension Manager). I was able to type again even after re-enabling all of them, so I'm unsure which extension specifically caused the issue, but that's another route to try for people who still have this issue.
I never had the problem until I installed plugins/extensions. Curious to know if anyone has had this problem without having any plugins/extensions installed. I don't know if they are the actual cause but since benefits of the plugins outweigh the occasional lockup, I have left them installed. BTW, I use the "closing/reopening of the window with the lockup" technique.
Using a source control (GIT, AKSVN)? If so, disable it, restart VS then enable it and open the solution again.
I am completely new to the whole FlashDevelop/Flash/etc toolchain, but wanted to do some experimenting. I installed FlashDevelop and Flex SDK on my laptop, and thinks worked out just fine, except for one thing: the compiler messages are localized!
Messages like "gebruik van een niet-gedefinieerde eigenschap" (Dutch.. sort of) are limiting my productivity. I don't recognize them because they look nothing like what I'm used to in any other programming environment, as a proper sentence they make even less sense than English error messages, and I certainly can't google them properly.
Now I've already seen there are a couple of xml files and java/mxmlc/fcsh/etc configs I can tweak, but nothing so far helped.
Please help me restore sanity and en_US/1033/etc! Thanks...
Edit Setting my windows locale to English through the control panel, then restarting FlashDevelop, did result in English error messages from Flex. So hurray, I've got a usable workaround. I'd still like the two to be unrelated though, as a developer a fiddle with those settings all the time.
Modify jvm.config file located in the same folder as your mxmlc.exe
by adding on java.args line the following option:
-Duser.language=en -Duser.region=US
Detailed explanation is here.
Goto Tools | Program Settings (press F10) and select Flash Develop from the left panel. Scroll down to the Misc heading - the last option is Selected Locale. If en_US is not there, then you have a problem - you might have to download the correct locale version again.
Setting my windows locale to English through the control panel, then restarting FlashDevelop, did result in English error messages from Flex.
I someone comes up with a better solution, I'll gladly accept that answer in stead of this one...
