Hello,

I 've ran into a problem. I tried to add a new field to Class whitch is contain file.
On the console everything is Ok (I can upload file, I saw the details and so on. On the Portal I can see the field, but I cant upload file.
I cheked the source and as I see the code isn't complete in portal side (BsFileUploadFieldRenderer). It work only for Attachment class..
Could anyboudy give me some advise how can I use AttributeBlob in portal?
Thx
