I have been working on a widget which generates images from certain charts. I want to make it possible for the users to download/view these images in the browser. The images are being rendered and FileDocuments are being created but I haven't managed to generate a proper URL to show the image in the browser. I have found a topic covering a similar problem on the forum and tried it link. Edit: I want to show an image in the browser by doing something like this and sticking it in a dijit.Dialog: <img src="./file?fileID=18" /> Browsing to the url directly shows this: { "type":"exception", "description":"The file '9630b66b-05ed-4ee4-bf2d-6f1f60b47cba.png' could not be found.", "result":560 } When I set a breakpoint on the microflow where the URL is generated I can see that the FileDocument.HasContents-attribute is set to false. But when looking at the file on the file system it looks like a standard png. The file is located in the applications temp directory.
