I am not a professional coder. But if you make the following changes in Form.ascx.vb/Private Sub CreateInputForm() and recompile, this seems to work...makes the file upload optional when using the Filelist Template. Should work for other templates but not tested...

Case "FILE"
Dim objFile As New HtmlControls.HtmlInputFile
objFile.ID = "__File"
PlaceHolder.Controls.Add(objFile)
' we're uploading a file for the first time ( ItemID=-1 ) then we need to insert
' a required field validator. If we're editing, we don't because leaving the field blank
' will leave the current file in place
If objRepository.ItemId = -1 Then
Dim controlType As String = oRepositoryBusinessController.GetSkinAttribute(xmlDoc, "FILE", "Required", "true")
Select Case UCase(controlType)
Case "TRUE"
Dim oValidator As New RequiredFieldValidator
oValidator.ControlToValidate = "__File"
oValidator.CssClass = "normalred"
oValidator.ErrorMessage = Localization.GetString("ValidateFile", oRepositoryBusinessController.LocalResourceFile)
oValidator.ID = "__ValFileID"
oValidator.Display = ValidatorDisplay.Static
PlaceHolder.Controls.Add(oValidator)
Case "FALSE"
'Do nothing
End Select
''If oRepositoryBusinessController.GetSkinAttribute(xmlDoc, "FILE", "Required", "true") = "true" Then
''Dim oValidator As New RequiredFieldValidator
''oValidator.ControlToValidate = "__File"
''oValidator.CssClass = "normalred"
''oValidator.ErrorMessage = Localization.GetString("ValidateFile", oRepositoryBusinessController.LocalResourceFile)
''oValidator.ID = "__ValFileID"
''oValidator.Display = ValidatorDisplay.Static
''PlaceHolder.Controls.Add(oValidator)
''End If
Else
If objRepository.FileName <> "" Then
PlaceHolder.Controls.Add(New LiteralControl("
"))
Dim objLabel As New Label
objLabel.Text = oRepositoryBusinessController.ExtractFileName(objRepository.FileName)
objLabel.CssClass = oRepositoryBusinessController.GetSkinAttribute(xmlDoc, "FILE", "CssClass", "normal")
PlaceHolder.Controls.Add(objLabel)
End If
End If

btw, it looks like the only fixes that did not make it into the Install package are the following..

1. added ability to enable/disable RequiredFieldValidator for [FILE] tag in forms
2. added ability to specify default text for [SUMMARY] and [DESCRIPTION] tags in forms

so, unless you are specifically having issues with those 2 issues, the .dll in the Install package should be fine. However, if you're reading this thread you most likely will need to either recompile the project in VS2003 or contact me for an updated .dll
