Bootstrap4 fileinput bug

[Rassamaha78]

I always have aRequest.Files.Count := 1
CustomRestEvents0RestEvent executes every uploaded file.

My code from DFM:

Code:

object IWBS4File1: TIWBS4File
    Left = 331
    Top = 144
    Width = 161
    Height = 33
    CustomAsyncEvents = <
      item
        EventName = 'fileuploaded'
        OnAsyncEvent = IWBS4File1CustomAsyncEvents0AsyncEvent
      end>
    CustomRestEvents = <
      item
        EventName = 'uploadUrl'
        OnRestEvent = IWBS4File1CustomRestEvents0RestEvent
        ParseFileUpload = False
      end>
    Script.Strings = (

        '$("#{%htmlname%}").fileinput({uploadUrl: "{%uploadUrl%}", langua' +
        'ge: "pl", maxFileSize: 2097152000, showRemove: false, showPrevie' +
        'w: false, allowedPreviewTypes: null});'

        '$("#{%htmlname%}").off("fileuploaded").on("fileuploaded", functi' +
        'on() {{%fileuploaded%}});')
    Multiple = True
  end

Which apptype are you using SA (IWStart) or HTTPSys(IWStartHSys)  ?
