    Could you please provide the visualforce page code and some description about what it isn't working? – Martin Lezer Jan 2 '18 at 9:41

    you could maybe share your visualforce page as well. And possible error messages that you have gotten or behaviors that you may have observed. – Nielsm Jan 2 '18 at 9:42

    This is probably because your apex:inputFile inputs have all the same id. Try to remove the id attribute. – Martin Lezer Jan 3 '18 at 8:05

For that error you have to reRender the whole "apex:form", not only the "apex:pageBlockSection". That is the mistake you done.

So remove id='repeat' on "apex:pageBlockSection" like following, apex:pageBlockSection columns="1"

Then add that on the "apex:form" like following, apex:form id="repeat"

Here you will get following error, "Rerender is not currently supported with rich text editing enabled"

Because, if the rich text area is "true", then we can't re-render that. If the rich text area is "false", then your attachment values will populate correctly. Hence you have to identify a different way for that one.

  • it doesn't work. – fdsfad Jan 2 '18 at 13:14
  • What kind of error message you got? – Venkatesh Jan 2 '18 at 13:33
  • System.EmailException: SendEmail failed. First exception on row 0; first error: REQUIRED_FIELD_MISSING, No body supplied for the file attachment.: [fileAttachments] Error is in expression '{!sendEmail}' in component <apex:commandButton> in page vcomp:sendemailmultipleattachments: Class.Vcomp.SendEmailMultipleAttachments.sendEmail: line 41, column 1 – fdsfad Jan 2 '18 at 13:36
  • attachment body and name are not binding in controller. – fdsfad Jan 2 '18 at 13:36
  • I edited the answer, this may be helpful for you. – Venkatesh Jan 3 '18 at 7:04
