Hi Mladen,
Look at solution used be me FileDescriptor in Jmix 2.0 - #3 by florin.tanasa
, maybe is what you need, also I added the code to get filename, extension and the size of file uploaded genedatabank/src/main/java/com/genebank/genedatabank/view/sysfile/SysFileDetailView.java at master · florintanasa/genedatabank · GitHub . The date used in createDate field from entity is the date used by users when they know/or not when the file was created/finalized, is not the same with createdDate from audit, when the file was uploaded.
