We've been struggling with getting a zipped static resource to work for weeks now. We got Salesforce Support involved from the beginning, but they've gotten us nowhere. If we can't get a resolution to this issue soon, we might just find a platform that wastes less of our time...


Here is the situation - we are trying to upload a portion of the YUI library as a static resource, but no matter what we try, we can't get the files to render in our VisualForce pages. Salesforce Support can get it to work (sometimes), but we can't. The difference seems to be around the MIME Type that is set when the file is uploaded. When we upload the file, it gets set to a MIME Type of 'application/zip', but when SFDC Support uploads the file, it gets set to a MIME Type of 'application/x-zip-compressed' or 'application/octet-stream'. Salesforce can't explain to us exactly why or how these different MIME Types get set. They're looking into why our uploads don't work, but I'm not expecting much from them at this point.


To reproduce our steps:


Download the file from here after clicking the radio button labeled "Full developer kit":

  1. Download "Full developer kit"
  2. Open zip and remov the documentation and examples folders (to reduce size)
  3. Change file name from "yui_3.0.0.zip" to "yui.zip"
  4. Upload as a static resource named "testyui"
  5. In component "header" (where all other JS files are included) add:
    • <apex:includeScript value="{!URLFOR($Resource.testyui, 'yui/build/yui/yui-min.js')}" />
  6. If we refresh the page we get a 404 error for this resource.
If anyone has experienced a similar issue, any help you could provide would be greatly appreciated.
