Not answered Sometimes not all the images will load

Elizabeth

Posted on Dec 15, 2009 (permalink)

On our sitefinity site, sometimes when a page will load, not all the images will load. It can be an image that is in the content or an image that is part of the template used by the page. If the page is refreshed, all the images will then be visible.

Are there any known issues with Sitefinity pages not loading all images sometimes?

I've attached a screenshot as an example. The "2" image in the tabs along the right is not displaying, but the source address when I look at the properties of the missing image is correct.

Hello Elizabeth,
Thank you for posting your question.

We are not aware of such problem yet. Which version are you using?

At the moment, I can only suggest you to inspect all get requests with Fiddler or another tool, and to check the server response code when you see broken image. You can also take a look in the Sitefinity.log file, and send relevant errors to this issue to us.
Best wishes,

This happens to all our Sitefinity 3.7 sites. Its random but very annoying. I installed the Elmah error catcher thing to track errors, and I get this error:

System.NullReferenceException: Object reference not set to an instance of an object.

Hi Eric,
A temporary solution is to disable the caching in the Images and Documents module. You can still use Browser cache though.

We are currently investigating the issue, and will follow up to this thread once know more about it.
All the best,

Hello,
We are still working on resolving the issue. Hopefully we will be done before the upcoming service pack, and will include the fix with it. Meanwhile, can you spot any certain pattern on reproducing the problem? Perhaps if you have several requests to the same item?

Thank you for your patience.
Sincerely yours,

We have turned off caching in the libraries. I haven't noticed any pattern as to when this is happening. On one of our sites (it's not 'live' yet but can be seen at brownrisd DOT hillel DOT org), I'm not seeing the problem but another user is. It got worse for him after he refreshed. His browser info:

Safari 4.0.4

Firefox 3.6

Google Chrome 4.0.249.49 (35163) beta

I've also attached screenshots that he sent me.

Hi Elizabeth,
We are still chasing the cause of the error. We haven't been able to reproduce this yet. Perhaps there is a way for you to send us your project? We can set it up locally and try to reproduce the problem there. Otherwise, we will update the thread with some more information once we have it (it's in my ToDo).

Hello Eric,

Thank you for getting back to us.

We are currently investigating the issues when using caching with the Images and Documents module. We have the issue logged and will try to come up with a fix for this in the upcoming Service Pack release.

I was just talking to another developer who has had the same problem. He's been waiting on a fix since version 3.5. That seems a little ridiculous that this has been an issue for so long, and the only solution is to wait to an upcoming release.

I just started a new site today using 3.7 sp2, got my images in the library, template created, and a splash page up... and the logo which is stored in the image and document module with the caching turned off, randomly does not appear.

I am going to bring this to my managers attention and make him aware of the lack of timely solutions and recommend we abandon Sitefinity altogether and use Umbraco.

Thanks for the lack of help.

Hi Eric,

The problem persists in 3.7 SP2 and I believe that we will be able to fix it for the forthcoming SP. I am sorry for the inconvenience caused.

Highly doubtful. I just installed the Elmah error handler on a 3.2 site, same image library issues. So basically we've needed this fix since the creation of the Image and Documents module.

So how many versions and service packs have been issued since 3.2 with no fix?

We get these errors dozens of times and multiple different sites and multiple different servers. It's really an unacceptable "INCONVENIENCE". What are we supposed to tell our clients?

Hello Eric,
The concept in 3.2 is rather different to the concept taken in 3.5 and later versions.

Could you please let me know if you are holding a Sitefinity license, since I see that you have downloaded Sitefinity Community edition only, which is not supported? It will also help if you can provide us with any certain steps, environment and possibly stack trace of the errors you are getting.

Thank you in advance.

Hi Eric,
Thank you for providing the stack trace and the error information.

It's coming from an application which is not 3.2 as said in your initial message, but is 3.7 - 3.7.1990. , at least http://www.danscoengineering.com/ is built with 3.7 and the error is from it.

We have scheduled regression testing and improving the code related to this error (since it's the same as in the previous messages) and hopefully we could release a fix in the SP3, coming in the mid of March. We will first have to find a way to reproduce this locally.
Kind regards,
Georgi

Hello Eric,

As far as I see it you use custom handler that seems to be the reason for this error and your problems.

ContentHttpHandlerFixture.ContentHttpHandlerFix.ProcessRequest(HttpContext context)
in e:\Sitefinity3.2\WebSites\Cortland32\App_Code\CustomContentHandler.cs:line 40
