Thumbnails are not loaded properly

[udayakumar_p]

When we click the smart folder, the documents shown inside the smart folder does not show proper thumbnail. When inspected, there is a 500 internal server error in javascript console.

Here is how it is displayed.

Do the documents really have thumbnails? Can you see the thumbnails when you browse them via share/normal folder?

If not - is there a conversion path form the mime type of your documents to then thumbnail (ex. pdf-->png)?

I see that the issue got resolved itself. Don't know the reason.

No, we don't have a conversion path.

The generation of thumbnails needs some time - maybe you were to fast :-) 

The first call for a thumbnail triggers its generation (mode=queued). If you refresh a age after a short time, you will be see the generated thumbnail.
