Can it be that you have added the mimetype in uppercase? Try 'application/pdf' instead of 'APPLICATION/PDF'.
If it's not your code setting the mimetype, then this can be a bug.

For that particular document, I would try to manual go into edit properties, set the mimetype to something random, save, then set it back to Adobe PDF. See if the transformation works after that.

Hi Loftux,

Thanks for the reply.

I have converted the mimetype to lower case.
Please refer the following code.


var mimetype = docNode.mimetype;
      mimetype = mimetype.toLowerCase();
      var fileExt = "";
      if ((docNode.properties["cm:name"]).indexOf(".") != -1) {
      } else {

            fileExt = ".pdf";
         } else if (mimetype == "text/html".toLowerCase()) {

Also I checked content property in repository which comes as contentUrl=store://2012/11/27/14/47/b50b9d2d-916c-4392-a3f5-46f34f9a236b.bin|mimetype=APPLICATION/PDF|size=21006|encoding=UTF-8|locale=en_US_|id=181070

Also as sugeested by you I had randomly changed the mimetype to docNode.mimetype = "application/vnd.stardivision.writer"; and changed it back to mimetype coming on doc,but still preview is not available.

I think you need to use docNode.properties.content.mimetype.

You can try docNode.properties.content.guessMimetype(string filename)

Hi Loftux.

I am getting "undefined" when i used docNode.properties.content.guessMimetype(docNode.properties["cm:name"]).
