Highlight Attachments of Unsupported Types
[datovka #945368]:
During send of new message we get error "ISDS server problem Obsah souboru nebyl identifikovan"
....
The problem is that the user is not notified when he is inserting attachments of unsupported types. Operating Rules of ISDS contain a list of attachments (file types) tat are allowed to be sent in a data message. The application should notify the user about those file that don't meet the conditions.
