I can upload and save the picture in the database without problems. However when I want the display that picture in the view grid the thumbnail is not generated and looks like this The web-handler that I use inherits from WebHandler and overwrites methods handleHead/get/put/post etc... The content type is set to "image/png" and the required ad-notations are used in the dataset that is used to create the JSDO catalog: @openapi.openedge.entity.field.property(field="FileJson", name="type", value="mr.image"). @openapi.openedge.entity.field.property(field="FileJson", name="format", value="string-json"). The Field in the JSDO catalog looks like this : " "FileJson": { "type": "mr.image", "ablType": "CHARACTER", "default": "", "title": "File", "format": "string-json", "contentEncoding": "binary", "readOnly": "false" } " When I'm the update mode and I click the link the following deep-link generated is: " localhost:8830/.../File and the picture is automatically opened by the browser. Anyone have any idea why the thumbnails are not generated ?
